Overview of Life Processes

Burning is called fire, roasted is called ash Are. and which is as complicated as science Make the subject easy for him Prashant Kiran says. So hi everyone, it's me Yours truly Prashant Bhaiya and bring I have gone, a dangerous, tremendous one shot of life Process. I know this chapter friend You have a lot of problems inside that brother how is this human heart Will you understand? there are so many names I don't understand I could have come. Nephron cannot be understood. Aerobic respiration is not understood Anaerobic hey brother today I will teach you the trick also I will give you and along with that the most important Question is the question which is in your paper You can repeat everything inside one It is available in the only one shot. Correct Is? So get ready because Ishant Bhaiya is here Have gone. and why to fear when PK bhaiya It is here. So remember there is nothing to be afraid of Is. How is the enthusiasm meter? Tell me that first. What is the energy level? What is the passion meter? Energy is very high. when your master is here If you are full of energy then how can you be slow? Are? What kind of energy are you? He is sitting very low. Do not take I have to sit. Have to stay in high energy. Ok? So let's start this chapter Are. First of all its heading is Life Process. Now look friend, biology is a very important topic It's a lovely subject. Why? do you say it People say that biology is a very lovely subject. Why? because look math guys, they will understand x The chemistry guys have gone out to look for it setting up your chemistry and Search for the poor Newton Baba of Physics and we are biologists, we are experts in life learning about it. and so in this chapter The name is life processes. Life What does processes mean? Process That means work. Life means life. That means all of them processes that make life worth living It is mandatory. That means it is important. i.e What are life processes? all thats functions that aren't basic and Essential activities performed by a Living Organisms to Sustain and Maintain Life. whatever it takes to stay alive what are those things to me? that for me Life process. now you will say bhaiya phone Driving is also a life process. without him We would not have been able to survive. Look friend, what do you know That should be a live process for you. Because Now you are addicted. On that phone get out of addiction because we I am studying. Ok? Operating the phone on There is no live process. ever ask in the paper Take it and come back after writing it. yes for us Is. PK bhaiya had said it. no no life There are basically four types of processes Are. And that is what this whole chapter is about. the first is Nutrition. Eating food. Yes. what is the second Is? The second is respiration. Creating energy. Next is transportation. Everywhere To transport. and last comes Excretion. You already know that. So There are basically four types. Nutrition, Respiration, Transportation, Excretion. What will we do with all these? We are going to read them one by one in detail. Come Go away. Let's start first From nutrition. Ok? Now Nutrition What is? what to eat bro is there nutrition? I said it was a wrong catch You have taken it brother. Eating food is not nutrition Is. Eating food and obtaining energy That means taking the energy from within as well. That The entire process is called nutrition. Ok? Now what do we do in nutrition do you eat things? such as carbohydrates You eat fat, apart from that you eat protein You eat it, you eat vitamins and minerals. Mainly so You only eat fat. Burger, Pizza, Everything I know it. Isn't it? this is what you are eating You. FatVat. no problem baby. So What is Nutrition? Remember this. The Process by which a living organism has and Utilize. this is a very important line Son. Utilize means to use that food, To get the utilization done. Isn't it? what even is that? It comes under nutrition. it is called Nutrition. Food Gives Up Energy, Growth and development. What does food provide? Energy Growth gives development. Everyone knows. If you don't eat food, you will die, friend. Obviously That's right. No brother, we will not die. Oho You will die brother. two three four days five days Don't eat food. The situation will become worse. Seventh On the eighth day. Ok? Yes that's why we have to eat food. Ok? There are four components of food. i you I have already told you. carbohydrates, proteins, Fats. Mainly this is what we eat. Brother I was watching the lecture. in the mouth at the sight The water has arrived. Now I feel like eating a burger Take it. no problem baby. I am hungry too, you Also hungry. Both will study. Look now There are two types of nutrition. Autotraffic and one heterotrophic. Auto means that one No auto, no auto, auto means by itself. i.e This is the type of nutrition that The organisms inside make their own food Are. Now you will say bhaiya our mummy again What does autotrophic nutrition do? because our mother doesn't cook her own food Makes it. I said it will take one. No, bro. Foolish child I call you foolish with love Boy. Ok? I shouldn't feel bad. You You are my foolish child. Correct? so stupid child It's not like that. What is autotrophic nutrition? There is a type of nutrition that contains yes The organism makes its own food. But from inorganic substances such as Oxygen, carbon dioxide, water. Oho The vegetables that are cooked in your house It is made from. What is a vegetable? Plant. So What is Autotrophic Nutrition? mode off Nutrition in Which Organisms Prepare Their own food using simple inorganic Substances like CO2, water in the presence Of sunlight and chlorophyll. Ok? Look now Son, there are two types of auto traffic. And understand these two types of examples. What is the first one? There is an autotraffic which what do we say? photosynthesis, which is Plants do it. even in smaller classes You must have read it. What are you saying? not studying Curry inside small classes. With friends Were having fun. No problem. Something No. Ok? Photosynthesis Green Plants do it. Ok? Gin Plants There is chlorophyll inside. About this We will talk in detail. just understand this right now that photosynthesis is a type of autotrophic Nutrition. Apart from this, good plants Besides who else does it? Autotraffic This photosynthesis in nutrition. then some There are algas. Some are algae. Some? Contains cyanobacteria. All of that too perform photosynthesis. In addition to that, one Chemosynthesis occurs. chemosynthesis a It is a process in which an organism rebuilds itself It cooks its own food but requires few chemicals with help. Is it okay son? so remember to type off Autotrophic Nutrition in Which Organism Prepares their own food by utilizing Chemical Energy. Now its example is very It is necessary. Has been asked repeatedly. Example There is purple, sulfur, bacteria. Variant. It has been asked many times. Ok? Importent I will show you the question now. No tension Lenny. I do not want to take the load. Where can I find the notes? You can join Telegram or else I will put it in the description as well. Ok? Ok, that's great. Did you understand it? Good. Now What was this heterotrophic brother? Heterotrophic like you, all of us. We The thing is that we are dependent on someone else. We are eating plants like that. so we don't We are dependent on plants for food. So That is what is called heterotrophic nutrition. The mode of nutrition in which organism Depend on the other organisms for their food Because they cannot prepare their own food. All the animals are on plants Are dependent. Look how important plants are yes brother. We feel that plants and trees are necessary Not there. Brother it is very important. without them What is our food? We eat our food I can't make it myself brother. If the plant How will the world function if they are not there? Look now First of all I will tell you the type of Heterotrophic Nutrition. Heterotrophic There are three types of nutrition. there is one Holozoic. Now look, don't get scared on hearing the name It doesn't happen. I know biology in 10th You have come just to see biology. Brother what is this did you read it? Holozoic. Hey wait. One Holozoic, one saprophytic, one parasitic Understand. What is Holozoic Nutrition? Holozoic. What do you understand from Soik Holozoic? Some? It is a big thing. That means we are also grown ups. So Holozoic nutrition is what we follow We do. What do we do? we are big picks up food and puts it in the mouth Put it and eat it. this is what you do No? like this and when you have to eat a burger then do this We do come, right? Isn't it? same with you what happens? at school when your The friend brings Maggi inside the tiffin box So that tiffin box before recess It opens and everything starts crunching, crunching, crunching. He eats it quickly. Isn't it? whose The faster the speed of eating, the He will eat more. Isn't it? Yes. So, holozoic What is? animal take the solid food which is Broken down inside the body. Example What is? We are animals. and one more Organisms are unicellular The organism is called amoeba. Amoeba. Ok? ok let's read parasitic now What happens? what is parasitic nutrition Is? Parasite. do you understand parasite Is? Have you seen that Annie? Parasite. Is No? So look friend, this is parasitic What is nutrition? be careful Understand. A parasite is something that be on someone else and get your food from him Pull. Like for example in childhood You used to say that you had lice in your hair. Hair What happened to me? I got lice in my hair. Did you say it or not? Tell me quickly. You used to say that you had lice in your hair. Joo Jo What did you do to your hair? Your Used to remove blood from your body. That is, what is parasitic nutrition? Type of nutrition in which organism lives Inside and outside the other organism. That means it is in our hair. so what is that Is? That is up to us. Ok? above us and what are we to him? We are his Host for. Host means the one from whom he can Provides nutrition. Ok? And derive nutrition from it. remember In parasitic nutrition the parasite It happens, it doesn't kill the person in front of it Is. I just keep on getting my food from him Is. Remember the example. Substantial Example Is. Cuscuta cuscuta. cascata What is cuscuta? It is a type of plant And that's why I'm telling you to remember this This is the only plant which Parasitic nutrition follows. This is the only plant like this, how is it cut, right? His What are the additions? There are ticks, leeches There are. Do you know leeches which suck blood? Are. yes very good brother blood and that too She sucks mine. No problem. Something No son. Let's go, right? Yes. you are the crazy one yes. Come on. Talk of Saprophytic Nutrition We do. First we understand the Holozoic Parasitic I have arrived. Now this is the worst kind of saprophytic. What does this do to Saprophytic Beach? it Na eats dead end [ __ ] organisms. But there is one thing in this that you should not eat It digests it outside itself. to eat It digests it outside itself. some chemicals It removes it so that the food gets digested outside It happens. and then directly Absorbs nutrients. i.e What's inside it? Organisms Feed On Dead end decaying matter. remember this is outside digests and later absorbs He does it. Its example is fungi. And What is the biggest example? mushroom. Write it down brother. One of the biggest examples is What? mushroom. The mushroom that you eat is a Follow the same type of saprophytic nutrition He does. he'd be eating dead and dicken Is. Did you understand this? Just tell me. If you understand it very well then move ahead. here come Did you understand? Now let's look at some questions which are asked from here. came brother This is an important question. See 2017, 2020, 2021 see brother which of the following Is the organism saprophytic? Saprophytic See Holozoic Parasitic Beach ka bole yes saprophytic then who is in the middle Of these, I just mentioned mushrooms Who among you eats mushrooms? do you eat mushrooms mushrooms He eats saprophytic dead end dk remember this which of the following Organisms Show Parasitic Mode Parasitic Which of these looks like a parasite? cascata cuscuta will remember son will remember next What is such a big question? Nowadays, elder ones are coming. big paragraphs They give it to you and ask you a small question Are. as an organism was discovered That lacks chlorophyll. it has chlorophyll Not there. survives by penetrating the tissue of another living organism from Which it absorbs the nutrients. However it neither kills the host. That means he He does not kill the person in front of him. Just Absorb He does. Hey, you already know this. These So you already know it. The Last One Parasite Parasite. very nice. That is, it It is parasitic. What is Parasitic? Its The name is. okay brother? Parasitic. These Remove the autotroph from here brother. remove this From here. Ok? Not this, brother. Not this. Ok? Remove it from here. What is? They It is a type of parasitic nutrition. That means, what is he doing to the person in front of him? They is obtaining. Please look at it. he doesn't kill As for the person in front. it show specialty by infecting only a particular plant Species. Ok? I've got it? very nice. Let's go brother. Now let's move on to the next one. Autotraffic In nutrition I told you that photosynthesis what was i I will talk in detail. and kids like this Bhaiya it seems that in 10th photosynthesis is so much Easy who will ask? and whoever asks They also ask about the reaction. Photosynthesis How does it happen? There is a plant. of the plant Green leaves. I for you I have also brought the plant. where did mine go Plant? Brother, where did my plant go? Wait brother. Here is the plant, friends. Your We present to you the plant. Are? Now no one He will not say that it is a fake plant. So look brother In this we saw that flowers have grown in the plant have given. But this green part is What is the green part friends? so this is green Its part is chlorophyll. That is, this green The pigment is due to this green pigment Photosynthesis occurs. Isn't it? Poor this So I can’t do it. This poor guy is fake. Isn't it? So this is fake. what can you do Are? but because of chlorophyll Photosynthesis occurs. Good photosynthesis And what other things cause this? Understand. The first is chlorophyll. The second is the sun light of. The third is carbon dioxide. Fourth is water H2O, very important. Correct Is? So first of all see the reaction and this The reaction must be remembered. forget this one It is not even by mistake. What is the reaction? What things are combined? 6 CO2 + 12H2O. Now look there are two things. chlorophyll Sunlight. Isn't it? Both of them come. and then what makes? Food. and what is the food? Glucose. Glucose itself is food. Glucose Remember the formula of . C6H12O6. then glucose is formed simultaneously Oxygen gas is released and H2O gas is given out H2O is not gas, H2O is water that is coming out okay so what did we understand very good okay so these are the raw materials What are the four CO2 molecules for photosynthesis? speak with CO2 H2O and what is sunlight and chlorophyll is great friends let's go so remember what chloroplast is the sites of photosynthesis which are green Pigmented means there is a thing inside it which is called The one I am talking about is not the green coloured one What is that? Chlorophyll. That is if it is This is because of chlorophyll. Ok? very nice. ok now remember the events What events occur in photosynthesis Are? So the first event is Absorption of light energy. Look at this Let us understand the story in detail. To all What will happen first? My leaf is a leaf. Leaf Green Leaf. He keeps the sunlight with him He will call me. Sunlight come to me come come. Now Sunlight came to him. So what did he do? As soon as I called sunlight to me He was trapped. Caught in your net He took it. Trapped all the energy. Now what did he do? that light energy Get it broken down. Conversion in second step of light energy into chemical energy. For him converted into chemical energy. See What are you doing wrong with the light? Now that What did he do with the help of chemical energy? The water that was there, the molecules of that water broken down into hydrogen and oxygen. The hydrogen inside broke down into oxygen. Two The work is done. Now the third step and the most Important step. Now this CO2 was not CO2 carbon dioxide gas is converted to Who does it go inside? Carbohydrates. Carbohydrate means glucose energy. So What is inside this energy? Convert It is done. So there are three steps. First I called him over and trapped him. Chemical Convert it into energy. broke the water and what did you do after that? Carbohydrates to CO2 Converted inside . not very simple Is. Hey simple. This seems difficult. These You are really having a hard time. Who It seems so difficult to say it. O dear This much is easy. what are you talking about friend Friends? Ok. ok one more thing to remember It is very important to note that the plant Stores glucose in the form of starch. That means the plant is in the form of starch Let's store it. and the animals that are The glucose that is stored in animals In whose form do we do it? Glycogen. In whose form? in the form of glycogen Let's store it. okay brother? to glucose Stored in the form of glycogen. And they store it in the form of starch. Are. It is asked in MCQ. keep in mind Take. I will then tell you all the questions. Now let's talk about these gases, brother How is the exchange going? This CO2 comes in Used to be. The oxygen is running out. How are you Used to be? This is done by stomata. Stomata What is? It is a type of knuckle. Por ie hole. now these holes as i am going to show you for Let me explain you the example. accept accept look There are two such cells here. this is such There are two cells of this shape. To these we It is called guard cell. Guard means this guard Is. Ok? Now what do the guard cells do? As soon as water enters the guard cell The guard cells open up. open as soon as water comes So the stomata opened and the water went out The guard cell was closed. water came open water Gone is it stopped. Ok? then the stomata Who controls? This is its diagram Son. Diagrams have been asked for many times. Remember the diagram. This is what you can see Ho bean like these are guard cells. as soon as If water comes in them, son, then it is called stomatal pore Let's open it. and as the water ran If it goes away it closes the stomatal pore We give it. Ok? ok remember this diagram Keep. Inside this, this is what gives you green-green You can see that this is nothing. this is the same Chloroplasts. chloroplasts very nice. Ok? Let us understand this Went? All things run with water. Good What are the functions of stomata? first one is you know one thing is exchange of gases There is one more function. Do you know what happens? Never put too much weight inside the tree There is access to water. There is too much water. so no This water comes on the leaf. and what about the leaf It happens, right? that the water flows out of the leaf goes. And that is the process we call Transpiration. Perhaps you have studied in the lower classes You must have read it inside too, son. one job then There is exchange of gases. The second is loose large amount of water vapor during Transpiration. That is, transpiration is such a What is the process that happens? Who Access of water happens with the help of leaves drops out. have you ever seen this If yes, then the leaves of the tree are a little wet You can see it due to transpiration. So stomata have two functions. One Transpiration and the removal of a gas To get the exchange done. Ok? understand what is the matter Did I come? very nice. nice something Let me tell you the observation. For whom? For Desert Plant. Now look at the desert The plant is totally different. this was normal Plant. Now with desert plants This is a huge dilemma. There is a crisis. what that Friend, if there is so much sunshine during the day. If brother He will open his stomata during the day. If the sun is shining then all the water will go away. Poor guy, he will die. so this is not a game plays. What is he doing, son? be careful Look Stomata opens at night. That means night It opens the stomata more quickly He calls. CO2 CO2 come come come come come Come. And keeps the CO2 inside itself. Ok? So that means it keeps the CO2 inside Is. And then what does he do during the day? Keeps the stomata closed. Photosynthesis at He does it. because the light is on during the day It comes. So photosynthesis happens during the day only will be. It can't happen at night. Ok? So Stomata close during the day. and then What happens? CO2 taken at night used for Photosynthesis. photosynthesis during the day CO2 was trapped at night. is smart Desert Plant. Smart son, smart. He turned out to be smarter than you. I felt That you were the smartest one, son. But what did this one turn out to be, even better than you? Turned out to be smart. Let me ask you some questions. What are Stomata? Such questions have been asked. What is stomata? Do you know? What Is? Tiny Pores Present Mostly On The The under side of the leaf. on the underside of the leaf What happens? There are tiny pores which what do we say son? stomata speak Are. very nice. next question where are Are they located in the plant? located in the leaf There are. Ok? state to function of the Stomata. Give two functions of stomata Brother. Transpiration and gas exchange. also explain how there opening end Closing is regulated. who controls Is? Guard cell. The water came open. the water went Closed. Very true. Let's look at the next question Are. This is an activity. This is not a question Is. This is an activity that you will see Nor do many teachers get it done. Butt I Every activity, everything for you I have come, son. Everything is in detail Let's read. Ok? and that too for a short time Let's read inside. This is it PK bhaiya of. Ok? Yes, I flexed it. Let's see what's inside it? One This activity is within NCERT. not in this There is a salt called KOH i.e. potassium Hydroxide. He is kept. Now remember Keep in mind what does this salt do? This converts CO2 into It absorbs it. That is, carbon dioxide and absorbs the carbon Eliminates dioxide from nature. That means carbon dioxide is finished in this place It's done. what happens now? this pot this jar It is kept inside. this tree was kept Is. The sunlight is coming but isn't it? Unable to do photosynthesis. Why not can I do it? Because look how it is kept. It has what did you do? CO2 pulled. and you know If photosynthesis is to be done then four raw materials are required Material is important. if any of those four If any brother goes missing then there will be trouble It will go away and there will be confusion. and one brother is missing Done. Which brother disappeared? CO2 is missing Done. Now if CO2 disappears then never will this What won't be able to happen inside the case? Photosynthesis will not occur. this activity Remember to. Sometimes questions come up What does KOH do that? then KOH is absorbed It absorbs CO2. Let's go sir. very nice. Now let us come to the next topic. Nutrition These amoebas. The entire plant was destroyed. Now We are talking about holozoic nutrition Which is what we do. one more besides us It was a creature. Who? Amoeba. other than amoeba And the creature is Paramecium. So now We will talk about amoeba. some water for a minute I will drink it. So let's go brother amoeba Let's read. Then another friend of his whose The name is Paramecium, let's read it. Good Have you ever noticed one thing about friendship When there are two friends inside then it is very big Good things are happening. two friends It is a lot of fun. would have been hilarious Is. But when there are three friends then one person that I would have been continuously insulted Is. One of them is having a great laugh. two people laughing have been. Isn't it? I also had two friends used to do it. Isn't it? And I had two friends. Is No? My two friends, none are rich, none are poor Neither anyone is rich nor anyone is poor, I had two friends both of their pigs Well, we used to say that to each other It's a matter of time, I mean I'm bigger than you I am not big but it's okay, come on over Brother, let's talk about amoeba. inside the amoeba What is? There is a five step process and each These five are included in a Holozoic Nutrition There are steps. What is the very first? Ingestion. Ingestion means putting food inside Take. Ingesting food. So first of all Remember what is an injection? Amoeba Surround the food particle using finger like Projections called pseudopodia. Pseudopodia. It has hands, what is their name? Pseudopodia. Ok? It has hands Which we call pseudopodia. help him what does one do with it? takes the food in Is. Suppose you want to eat. I ate like this Took it inside. So what did I do? Ingestion Do it. The next process is digestion. What is digestion? Enzymes Are Secreted Inu Food Vacuoles Breaking Down the Food Innu Simple. That means breaking down that food Do it. Get it digested. the next process would be There is absorption. Now look at digest food I have digested it. Now that food which there is amoeba inside it so it should be absorbed as well It will have to be So that is what we call Absorption. Digested food is absorbed into a cytoplasm and used For energy. Next comes assimilation. Now this Assimilation is very important because Children don't understand what it is. Even absorption is understood. Assimilation I don't know. See What is Assimilation? I It has taken away the energy. now that energy To utilize means to move here and there, a little Moving here and there. What is happening to him? Energy is being used. so the same process We speak of assimilation. That is, absorbed Nutrients are utilized in various ways Life Processes. and here comes the next one ization. The last elation. ization. ization means Throwing out undigested food. Memory There will be ingestion, digestion, absorption, Take out assimilation and escalation. Now this Son, the diagram has also been asked about repeatedly. These Remember the diagram. First an amoeba Is. Where did this cookie-like amoeba come from? Are you gone brother? So are you feeling the cookie or not? Isn't this a tasty cookie? So food Part this amoeba what is this? Pseudopodia. Takes it in with the help of pseudopodia. Ok? So what did he do now? It inside Took it. After taking it inside, it destroys your food inserts it into the vacuole and Digestion begins. so here you are You can see that digestion has started. Now As soon as digestion started then here What happened? Absorption and assimilation Happened. Isn't it? The absorption energy absorb and all the life processes have worked inside it. and the last step What happens? The last step is outside Removal that which is waste, to What does it do? is thrown out. We call it isation. So these five Remember the steps. If you remember these five steps If you do that then you won't face much problem. Ok? Now he has another brother whose name is Perimysium. Look at Paramecium and Amoeba All the processes of both are same. just one It is different. First step is ingestion. amoeba what used to do it? eats food with the help of pseudopodia Was. What is he doing, son? It does not have There are hair like structures. whom we Says Celia. Celia. this diagram too It is important. It is not that important. Butt is fine. This looks like hair to you Projections are visible. We call them cilia I say it. Son, this is Paramecium. These There are cilia. So what does it do? of cilia do not bring the food to your mouth with help He comes and puts it inside the mouth. Is No? just inside the mouth of Lae near the mouth He puts it in. So that means only the injection is different Is. What is in a paramecium? There are cilia. Everything else is exactly the same. Other The steps are almost the same. digestion, What is absorption, assimilation and last? ization. It is exactly the same. He is Amoeba's brother. That's why I said in the beginning that he is my brother. Ok Brother very nice. ok now a question Was asked repeatedly. differentiate between Amoeba and Paramecium based on mode of Nutrition. What is the mode of nutrition in these Both of them? It's the same, son. Holozoic Nutrition. Holozoic Nutrition. Beans. Next is locomotion. locomotion i.e. movement How to do it? So the amoeba moves With the help of pseudopodia. And with whose help? does it? Paramecium cilia. Hair Like Structure. Very good son. Let's go a lot Correct. Now finally friends humans have arrived 's turn. Now look, humans are also hollow I am doing nutrition. then humans are also five Will follow the steps. The same five steps Ingestion, digestion, absorption, assimilation, ization. Now I remember it. Yes. Ok. Now Look, those are the five steps. where from now does it start? Eat asked for this diagram Has gone. has been asked. asked many times yes bhaiya. with a very sad atmosphere I have to tell you this diagram. asked this Has gone. So remember this. Look at the start It happens that we eat food. Now brother give me food If I want to eat, how will I eat? hey from the mouth I will eat it. from my mouth then I'll pick it up with my hand and I will put it in my mouth. This is what I will do. So that The process is called ingestion. Ok? Now Where does the digestion of food start? People feel that food gets digested in the stomach It is not happening nor is it starting in my mouth Is. Yes, it is starting in the mouth. Let's see one by one what happens? You give me an example. what to eat You? What do you want to eat today? what you If you say so, I will imagine that food. As I imagine. Burger, Pizza etc Do you want to eat? Momos, noodles, aha aha. No Son, whatever you want you will get it. This has happened till now and will happen today. So today we will eat Son, gourd vegetable. have loud applause Go and eat the gourd vegetable Lets do it. So now the gourd vegetable has arrived And you and I have eaten it. Ok? Correct Is. No no, it is good. of gourd Vegetables are good. healthy healthy Healthy. Ok? So now we have eaten the gourd Vegetable. So see what happens first, son. Is? first comes first our In the mouth. Ok? in the mouth and in the mouth What happens? what is the work in the mouth Is? First there's the crush. Food. this that Wally doesn't have a crush. There is a crush on food. Food It starts breaking. Ok? So what happens? First up would be a food crush. After that Salivary gland is present in our mouth Inside it releases saliva. Saliva You already know it. Ok? then saliva It is released. Now the main work begins. Look at our tongue, that is saliva She mixes it with the food. what would happen now Isn't it true that saliva contains an enzyme Is. Remember the enzyme and its name That is salivary amylase. Now this What does salivary amylase do? this which Complex sugar is complex, isn't it? Sugar means starch means starch. Starch what does one do to? these maltose Maltose. Remember this is a simple sugar. So what does this complex sugar do? This is inside the simple sugar which is maltose It converts it inside that. who is doing it Is? Salivary amylase. Salivary amylase. very nice. Now the food goes downstairs. Esophagus means food pipe. food pipe to eat How does one push down? there was a movement Is. This way this way it doesn't happen. Contraction is a movement like this A little bit. Isn't it? So we call that movement It is called peristaltic movement. so food is Push down through a peristaltic movement. What happens? rhythmic contraction of muscle In the wall of the alimentary canal. What is the alimentary canal? About that I am coming. I am coming forward now. stop Go. Ok? So what is in the esophagus? Is? A movement is happening, contraction Of expansion. we call it that Peristylic movement. Remember this. Ok Brother? How far had the story reached, son? Story From here ding ding ding to here now But it came. Now the stomach has arrived brother. Look now First of all, what shape does the stomach look like? You? J shaped is J shaped. Ok? Now as soon as the food goes into the stomach, the stomach There were three brothers sitting in me, all three were brothers. Three He was a brother. I asked who were the three brothers? So first comes a brother. which is bigger He was my brother. The name of the elder brother was HCL hydrochloric acid. then read one by one I will take it only. Let's start one by one Are. Now there were three brothers in the stomach. all three were Brother. What happens first? To install HCL. By the way Look, the stomach releases gastric juice Is. Gastric juice. and the same gastric juice All these three things are present inside it. Ok? So the first brother is the elder brother HCL. What does HCL do? Is? Creates acidic medium. That is, as many as There are also germs, bacteria you burgers, Eating pizza kills them all. All those which the golgappa wala bhaiya made dirty I touched it and it hurt him. Tata bye-bye. Good Bye. Isn't it? It has another function. about him Let me talk further. Ok? the first Given acidic medium. Next comes the . Second Brother, mucus comes. This is second brother. Mucus What does brother do? He protects From elder brother. Now look, HCL is inside the stomach Due to this, the wall of the stomach can get burnt. So what does mucus do? Mucus is a Creates a protective inner lining Inside the stomach. So that your stomach It doesn't burn and he survives. Correct Is? Next comes the third brother, Pepsin. Pepsin. What happens to P? Protein. That means, what is its function? of protein Digestion. Ok? Now look at the big brother He used to help his younger brother. Because pepsin can only work in acidic Environment. And who provides the acidic environment? Used to be? HCL is giving it. Because of this I I told you that HCL has another job called Help Pepsin Action. i.e. to make pepsin work Who is helping me also? HCL is doing it. Ok? ok now tell me one thing Have you ever had acidity? Acidity Why does it happen? This is why acidity sometimes occurs When is this balance of HCL and mucus the level of HCL increases in it and when HCL levels increase and mucus is less mucus is thin what is mucus a There is a lining on the wall of your stomach You start feeling a strange burning sensation in your stomach It seems like oh brother how can this jealousy happen It is inside the stomach and this is the reason why it is son, when the levels get spoilt, the levels Everyone will come out, it's okay, the levels change okay with HCL and mucus now lets go down Now the food was going downstairs, now go ahead to eat I had to go near the small intestine Give a name to the small intestine I am a small don. Why? Because its It is small only in name. otherwise it is small No. Isn't it? It is small only in name. But This is Don, son, chota don. Why? Because It is 7 meters long. 7 meters to you Do you know how much it is? It is 7 meters long It happens brother. It is small only in name. Work It is not small. Ok? Now it was going to By the way. The food was on its way. go to eat It was in the small intestine. Then there are two Entry of goons. bring the goons Friends. So now tidying tidying has arrived Tiding two goons. The first goon comes and The goon says yes where are you going to eat where are you going then the food said that Bhaiya he is going there that small Near the intestine both the goons He said let us also help you a little, who are the two goons If you look carefully, son, he was a goon Who is this goon, this is Lever and the other one is Chota are you looking at this pancreas what is this pancreas and what is this liver okay now What happened was that I was going to eat food and two goons came The liver comes first, so the liver speaks First let me help you a little, now for the liver What did you have? There is no bladder near the liver there is a storage which we call It is called gall bladder. inside the gall bladder He keeps a juice stored. These Gaols There is a bladder. He keeps a juice store What do we call that? Bile juice. Now he Bile juice does two things. what-what does it? We will read about it in detail Let's take it. Come on. So the liver comes first. Is. Bile juice is present in the liver. Two drops of bile juice Work. Make food alkaline. Alkaline means Basic. Look, the food was acidic in my stomach Due to h c l. that basic became alkaline Done. Ok? second its another work Emulsification of fat occurs. What is emulsification of fat? What is emulsification of fat? Fat's Nor are there large globules. For them Break it down into smaller parts. Correct Is? breaking into small droplets or Then we can say that the globules are there are these large globules, What does that do to them? of small globules It breaks the inside. Ok? Emulsification It does it, it breaks down. Two Did the work. The first goon was happy that I also helped myself to some curry. know now what happened? The ego of the other goons comes Went in the middle. Now he said that you what did you do? You have done two things. friend now So I have to do three things. Talk on Ego I came, otherwise her aura would not be greater than mine Will go. So the other goon said no Friend, I will have to do three things brother. Three tasks. So the other goon was my son Pancreas which I have just shown you in the image It was shown as well. So what does the pancreas do? Is? The pancreas releases a juice. Pancreas Pancreatic juice. and inside it There are three enzymes. There are three enzymes Are. I told him not to do it, then he did it Three will do. He is also a goon, not much work Will do it. Ok? So it made pancreatic juice Release three enzymes. The first enzyme was Trypsin. Trypsin is coming in trip Is. P means what will he do? These proteins will digest it. Now you will say brother Pepsin is also used to break down proteins. Yes Pepsin does it too, trypsin does it too Is. next lipase you're eating fat right Who will digest that? Lipase will do it. And next comes pancreatic amylase. Well, where did we hear this word amylase? amylase we had heard brother saliva Amylase. Pancreatic amylase here. So the job of amylase is the same here as well What will he do? The starch is the starch the digestion of carbohydrates It will help in digestion. Ok? what happens in the digestion of carbohydrates will he do it? He must be helping. first goon two Work. what did you do? Extracted bile juice. bile juice what did he do? Two tasks. Emulsification of Fat And made the food basic. Made alkaline. What did the other goon do? Three tasks. a juice Get it released. Three things. Trypsin, Pie Protein, lipase, fat and amylase, amylase Carbohydrates have the same function Do a breakdown. Ok? now what is here Happened? Here both the goons became happy and Then the food goes down to the small intestine Near. Isn't it? Food in the Small Intestine If it goes, then finally this small intestine yes son. Final Inside the Small Intestine Digestion takes place at this place. It is here that the final digestion takes place. Correct Is? And what is produced by the final digestion Is? You should remember that. The protein you If you eat it, it gets converted into amino acids Went. okay brother? The carbohydrates you Whatever we ate got converted into glucose. And the fat from the burgers and pizzas that you ate that's in your fatty acids and along with that got converted into glycerol. these three Things have finally come to you yes friends. very nice. Let's do all of this Did we understand everything, son? Quick Tell. Is it done? It is done. Now this is Chote Don's What's the work? Of the small intestine. Yes Digestion happened here but its just a small work Not there. This is Chota Don. another function of this Is. Now what does he do, son? this not its There is another function which is the absorption of Food. Digestion has happened. What was the next step? Absorption. so it has some finger like It's a projection, son, what do we care Do you say anything? Which we call Vilay. That is, assume that this small intestine There is a wall of and from it a finger like Projections occur. Finger Like Projections which we call vilay. what do you say? Vilay. Ok? So what Is? absorption of food in small Intestine. What is a Vilay? Finger Like Projection. in the inner wall of the small Intestine. Ok? on the inside wall Has finger like projection. now its finger Why is there like projection? know of it What is the work? which is the absorbed food no this means digested food Absorbing it and sending it into the blood. Its This is work. So there isn't a lot in it There are blood vessels. Such blood vessels They happen. So what does it do? to eat Pulls it and throws it in the blood. Correct Is? So what is its main function? Its main What is the work? The main work is absorption. Apart from that its finger like projection Why does it happen? because they increase surface Area for absorption. Now this finger It's like a projection, right? It's like a finger projection Why is it? A question might have come to your mind. Because this is a finger like projection No, this would increase the surface area more and more food can be absorbed. Ok? Next thing rich blood supply helps Transport absorb nutrients into all Body cell. because there are a lot of There are blood vessels. so that to eat It absorbs it. Ok? Nutrients are used for energy growth end repair. You already know that. Correct Is? So that means there is absorption here as well Went. Who did tiding tiding tiding? Vilay. There is a lot. Now comes the next large Intestine. Now its name itself is Large. Its work is not large brother. What is it does it? Let me show you. Here it is Large intestine. This is a big one. This large What does the intestine do? which is undigested If there is food then it will go here. and undigested What will you do with the food? It will draw out the water. Who There is water, it will pull it away. and then this vest You can see this right in the west through the anus he goes down to your waste you excrete it, you already know it It is already there. Ok? So what does the anus do In the last? The function of the large intestine is Absorbs water from the undigested food. And what does the anus do? Anus does ejaculation That means removal of undigested food. Correct Is? Who controls this? one muscle There is anal sphincter muscle. He controls it He does. very nice. I understood this thing. Now One question is asked repeatedly in the paper the herbivores inside which are like Cows, buffalos, all these have small intestines She would have been bigger in comparison to us Is. Why this discrimination? This discrimination is because Because they have to eat plants. of the plant the cell walls are made of cellulose It happens if you remember. Correct Is? Now it takes time for the digestion of cellulose Is. Their digestion cannot happen quickly. So Because Desegregation Takes Place That Is Why There small intestine is larger. Ok? I have written the answer for you here as well. Is. Ok? very nice. Let's do it You have your whole story now, right? We ask questions that will help you understand more Things will become clear quickly, its answer Tell me this is very simple, what is it I am facing a problem brother, see what is the matter inside which enzyme is secreted in the mouth and what does it digest which one The enzyme comes from the mouth, hey brother, amylase What breaks down complex sugars? breaks down starch into maltose It's very good, okay, it's important brother yes it starts from the mouth Your mouth waters, mom She cooks tasty food. Yes. Good Have you ever noticed that when you come home if it is from anywhere then first of all we What do you do? first of all we are our mother Let's look for the . Where is mom? where is mommy Is? where is mom? Papa asks everyone Where is mom? Where is mom? Then mommy If she is somewhere around, I can find my mom Is. Mummy says yes, say nothing. All we need is mommy. Isn't it? Us Just want to see where mom is? What to do Is it happening? Bus. Mom we have no work From. So we need mommy. Have you seen it? I do that a lot. even today I do it. Ok? then see the next question Are. in human alimentary canal the specific enzyme juice secreted in the Location. Look, I have given three locations In the diagram. The first is location number one. These hey mouth. What happens in the mouth? Saliva Amylase. This is the second location. what was this Son? Liver. What did the lever do? Liver Bile Used to secrete juice. This is the pancreas. The pancreas secretes three enzymes. So now match the options. The first will come Amylase. amylase, the second would be bile juice and Third, trypsin. very nice. so the answer is B. Such questions also come. next Let's see the question. in human being When the process of digestion is completed The Proteins, Carbohydrates and Fats Are Break Down Into What? Proteins are broken down into amino acids. carbohydrates break down into glucose Are. And what do fats break down in? Fatty Acid and glycerol. So option number B. Let's go next brother. This is a theoretical question. And You already know this. state the role of the following hydrochloric acid, bile juice and pepsin. I don't need to tell Brother. What did the hydrochloric acid do? Two tasks. Kills germs. Acidic provides the environment so that pepsin can work Got it. What does pepsin do? to the protein It breaks it. What did bile juice do? Two Work. Bile juice is secreted by the liver. Two Reduces emulsification of fats and food Alkaline Basic-Basic. Yes very nice. Remember the story. Story of two goons. These It is very important. this is repeatedly in the paper has been asked. Importent. what are villas Are? Finger like projection present at Small intestine. why are they located in Human body? Why do these things happen? their work What is? Absorbing, Digesting Food To be carried into the blood. how do they help in Absorption in food? So you have to tell How do you help? So one thing is this surface Let's increase the area. Because These have finger like projections, right? What do others do? There are lots of them in There are blood vessels. So to eat this Directly inside the blood means digested The food is put into the blood. Let go very nice. One last question. complete The following chart. All you need is this chart It has to be completed. This is your homework. These You will tell me yourself in the comments. We are talking about the gastric gland. The gastric glands do three things. A What does BC do? gastric gland What is? Stomach. stomach what? three brothers All three of them, brother, this is your homework. Come on friends let's move on to the next topic the side that is Breathing or respiration. Look brother The next thing is respiration anyway because the next life process is respiration It happens friends. but but carefully Understand. Breathing and respiration are separate Is. What is breathing? What is breathing respiration? Respiration This is what we breathe, its oxygen Producing energy with the help of. i.e We are doing breathing but respiration Our cells are doing well. every single cell Does the respiration. do you remember me You will remember just one line, ninth class of. Mitochondria is the power house of the Cell. Isn't it? Anybody can ask this, brother Mitochondria is the powerhouse of the cell. Is No? he he he comes comes. I am also used to it Inside the school, people didn't think so that I would sit on the back bench So my teachers didn't think that If this isn't good to read then I'll go back I used to sit on a bench with my friends I used to have fun but I liked science etc. my marks were good so one What happened next? The teacher saw me and called me. that you are standing at the board now to solve the problem The teacher thought that I would not know it stood square and caught all the answers It was written on the board and I turned around and Sir said okay. You are good at studies but have more fun If you do, then brother, do back ventures also and Look, back ventures have also come and it is fine If yes, then look at breathing and respiration what is the difference in this first difference Understand what variant breathing is Breathing is a physical process Letting out the breath is an inhalation Inhalation, acceleration, breathing out Excretion and respiration are a biochemical There is a process, that is, your sales do it, son. Son, it is a chemical process. In Breathing There is no enzyme in butt respiration Enzymes exist because energy is produced. And what is energy produced in? of ATP In the form. Remember the power house of the cell Mitochondria. Yes. Ok? Breathing what happens in? In breathing only and Only your lungs work. Lungs and Whereas every cell works in respiration Is. No energy is released in breathing. Whereas energy is released in respiration The Form of ATP. It is also written here Is. Ok? ok this is from outside the cell There is a process. i.e. an extracellular What is process and respiration? Intracellular processes. i.e. inside the cell What is the process brother? Yes sir. Let's go here You understood this. So first of all, son Look at the definition of respiration. to the children A lot of problems arise. what is respiration Is? The Process by Which Organisms breaks down glucose into their cells to Release energy in the form of ATP. Which It is used for various processes. That means one A process in which what happens inside a cell It happens because we have digested the food With the help of that digested food, oxygen is produced Energy is created in the form with the help of of ATP and utilize that energy goes into all our life processes What I am able to say inside today is this ATP Because of this I am able to say that it is okay Great, okay, we are talking now first of all about respiration then about respiration You have understood the definition, but now The question arises that how much is this respiration brother it is like this so look at the respiration No, it is of two types. Understand that I give you this I will explain the whole process. but understand now There are two types of respiration. one is aerobic and one an aerobic one. Aerobic means when our If there is oxygen nearby then the presence of oxygen The respiration which is taking place in Aerobic. Aerobic. Ok? So aerobic means o It is coming, which means there will be oxygen here. And Anaerobic means there is either less oxygen Or there will be no oxygen at all. Ok? In the absence of oxygen. Correct Is? Apart from this, there are some differences Son. As these differences are asked There is a question inside the paper. Aerobic More energy is produced in respiration. Ok? More energy is generated. While N Less energy is produced in aerobics. And know it What are we doing in respiration? Breaking down glucose into energy. So the glucose present in aerobic cells is completely It breaks in a good way, brother. Isn't it? As He broke your heart. Something No. Ok. Ok. Ok. No. No. No, not that. Will not talk. Ok. You will remember the trauma, brother. don't tell us that Did. Ok? what is glucose here It breaks down completely. but here in What is partial glucose? It breaks. It does not break completely. Ok? I will give you examples with the help of a table. I will give it. Come on. An NCERT table which that this has been asked repeatedly in the paper Is. Look what's inside this table? Complete Here is a complete chart of the breakdown of glucose Of. How is glucose broken down? Now look, glucose first enters your cells. There used to be a cytoplasm. of the cytoplasm It gets converted inside into pyruvate. Inside whom, son? Pyruvate. what is pyruvate Is? There is a molecule. carbon molecule Is. Just understand this much. So first of all Glucose is converted inside the cytoplasm into pyruvate. Now pyruvate has three Ways. He is asking brother which way Should I go? This is one way it is Which has a lot of oxygen. So first if Pyruvate goes into the presence of oxygen So this respiration is yours Occurs in the mitochondria of the cell. You already know it. in the mitochondria happens and energy is released. Energy Along with this, two more things are released. Remember this. One is carbon dioxide And one more is water. These two things were also released It is happening. Is this clear? CO2 And the water is very good. besides that now there are two There are still ways left. on a path where There is no oxygen at all. Absence of Oxygen. when there is no oxygen at all I know it gives you energy. Less Energy is produced but a product is formed what is its name? Ethanol. Ethanol is the same Shri Shri Honey Paaji ji had gone saying four Bottle wood work is my daily routine. Ethanol means Yes, that is what ethanol is. Ok? Correct Is? Ethanol is alcohol. Ok? then one ethanol is formed and one is carbon dioxide and energy at the same time It is made. Apart from that if we assume a lack of There is oxygen, which means there is limited oxygen. well this is what it is first absence of Oxygen is not an organism yeast. One organism is called yeast. His This process is happening inside. Correct Is? And if there is less oxygen. like it ever Sometimes we are playing football and our Do you know if there is less oxygen in your muscles? will be? Energy will be produced but a compound will be formed Whose name is lactic acid. the one who Do you suddenly get leg cramps? I start having pain. have pain in the hand goes. that is due to the formation of Lactic acid. yes because what is your body Still working? Respiration in lack of oxygen Still working. because of which yes this is the process Is. Understand? Because of which what is happening? Yes. lactic acid is being produced and you The cramps are coming and going. very nice Son. Now look I have told you an aerobic Explain two types of respiration. Aerobic then You must have understood it. n aerobic two Please tell me the type. one that has absolutely no oxygen Not there. One that has limited oxygen. Now these also have some names in which there is absolutely no oxygen in it because Alcohol is being produced. so his name is Alcohol fermentation. Alcohol fermentation. Ok? its name is alcohol Fermentation. Where does it happen? In yeast There is yeast. Isn't it? Yeast does this. Ok? And what do our muscles do? Lactic fermentation. because our muscles Creates lactic acid. Energy is created Just lactic acid along with it. and this The question has been asked repeatedly which is intense I got cramps while working out. They Why do I get cramps? Why have you come? Because our body has developed an aerobic I have had respiration done. Lactic acid is formed. Because of which I am feeling cramps There are. This has been asked over and over again. Correct Is? Now I will give you an example of this too Am. name the substance which is built up in the Muscle Vigorous During Physical Exercise? Look, he has come. what is made? Lactic Acid Along with this, energy is also being generated. Very Correct. next question. which gas is released During an aerobic respiration in yeast. Which gas is released son? Anaerobic Tell me in respiration. Which gas? Remember me Brother, that carbon dioxide used to form, right? Brother. Yes carbon dioxide is great. These It happened, right? Let's go next. what is this question Is? there is a boy who is running 400 Meter race. hey that's the question whether Is it happening? that he is in pain. His Heart beat is increasing. why is this happening Is? Tell me this. Why is this happening? After Why does intense workout happen like this? Its What should be the answer? Tell me quickly. Its There should be accumulation of lactic acid And increase CO2 concentration. When we are more When we workout, our body gets carbon dioxide becomes more because we are breathing more and a lactic acid is formed, which leads to I start having pain in my legs. Is this clear, son? Other than this There is one more question. complete the following Pathway. Very important. Such a question comes up. Look in this, I will tell you first and second Is. What will happen first, son? Tell. Glucose is converted into what in the cytoplasm tell me son it happens pyruvate pyruvate is very good and pyruvate in the presence of What does oxygen give? H2O gives energy It gives and what else did it give? Yes it used to give CO2. Very good brother you are giving the right answer Now let's talk further about whose human Respiratory system: How do we breathe now? Son, they see what I breathe I am taking it, how can I take it Without this, son, there are some steps. And This diagram is not asked about that much. Butt again You should also look at it, I will tell you once. the first There is a nose. I mean, what is there here? Nostril. Isn't it? So this is my first one There is a nostril. There is a nasal passage. with his help What do I do? I breathe. Correct Is? I breathed through the nasal passage. Oxygen Took it. Now what comes first? To all First comes the son Ferings. comes first Ferins. Then comes the larynx. Children Are you confused whether the larynx comes first? Is. First comes the firings. I have a trick I am giving it. PL Trick means profit loss. Profit loss. Remember it like this. then drink it first Wala will come i.e. Ferrings will come again Larynx. Now this fering that happens This is what we call voice box. this which I am not able to say no, there is no ding in my house ding ding ding ding ding ding yes yes What is? Voice box. Ok? Voice Box After that, this is what you can see This is trachea. what happens son? Trachea. Now there would be some rings on the trachea are the ones I call the rings of Cartilage. Now know this ring of cartilage what do you do? It Prevents Trachea From collapsing. if these rings don't Nor will it fall like this. It will fall like this. Correct Is? So this is a very important thing. okay brother? Now the breath goes in through the trachea and here But what happens? Divided into two things goes. Which we call bronchi. These which is going into the two lungs, we call it They say bronchi. Ok? Now the bronchi Such divisions continue to occur in the future. Whose Inside? inside the bronchioles. Inside whom? bronchioles. and at the end of each bronchiole Have you seen a bunch of grapes? bunch of grapes. there would be a bunch like him what is it that we call it? Alveolar Sac what do you say? alveolar sac i.e. in it Is it present? Alveoli. What is it present? Alveoli. Isn't it? Alveoli What is? talking about it right now Are. ok sir. So did you understand this? Breathed nostril. nasal passage from where Going inside. Then came the pharynx. First Ferrings. Second larynx. what are larynxes It happens? Voice box. comes again Trachea. What is in the trachea? Ring Of Cartilage. who does what? keeps it up Air way open. That is because of this we breathe Can take it. Ok? what comes after that Is? Bronchi in left and right. One goes beyond the bronchi bronchioles. and at the end of the bronchioles A whole bunch comes. and if If I talk about a grape, that means I am talking about I have been to an alveoli. Ok? Now this What are alveoli brother? this comes most Importent. Now this is coming the most Importent. What is this? Do you know? When you're breathing in oxygen and you're breathing out CO2 you are leaving it out. you know how Are you able to leave it? This is done with the help of alveoli doing. This is the brother who does this work Used to be. Now you will tell me how are you doing bhaiya Is? I didn't understand it. Look at what the alveoli are He does it, right? Alveoli are a very easy trick He uses it. alveoli first i will tell you I will tell you. it is a tiny balloon like Structure. Like let's say this is it Alveoli. Now the alveoli are the first ones, right? Its property is that it is very thin Is. and there would be a blood vessel going into it Is. There is such a blood vessel. Who is Blood? is it like? The blood that has carbon dioxide. So what does it do? That O my carbon speaks through blood Give me the dioxide and this thing of mine You should keep the oxygen in your blood. i.e Direct access of oxygen to our blood and we exhale carbon dioxide I leave it. Who is doing this? The alveoli are doing it. Now in your mind The question may be coming that okay we agreed. Alveoli are the site of gas exchange. We I agree brother, exchange is happening here Of gases. But how is it happening? how is this is it possibile? What kind of magic is that? So for this You will have to read a love story. One We will read a love story. Whose? one love This is the story of haemoglobin and oxygen. See What is hemoglobin? A Respiratory There is pigment. remember what is hemoglobin It happens? Iron containing protein is an This is a pigment which we call respiratory pigment also speak. Ok? It's our blood RBC means red blood cell. About this I will read it further also. There is a present in it. Now this has no love. Its love. It loves oxygen. So remember that What is? Who is his main love? Its main Love is oxygen. It is bigger than oxygen It's love. So what happened now, look at this There was alveoli. A blood vessel is going from here Was. Now there is oxygen here. to this blood showed oxygen oxygen it said By hemoglobin. me in hemoglobin Oxygen is needed. Take my CO2. Love There is a story. So it gives back CO2 in the alveoli and store the oxygen Took it. That is, the gases which can be exchanged This is happening with hemoglobin Because of. This is why we call hemoglobin It is called respiratory pigment. remember Respiratory pigments. very nice. Correct Is? So this is the whole process, son. Read out this oxygen from your body Alveolar air diffuses into blood capillaries. Ok? carbon dioxide from blood diffuse into alveoli There's CO2 inside. what happens now? When We exhale and breathe out The CO2 escapes out. The whole of this There is a process. These are the alveoli. Look at this blood. What did Blood have? I gave the CO2 here. Oxygen was taken in. because of whom took it? Because of hemoglobin. Let's go, that is Who owns the whole game here? Hemoglobin It is of. So what about Alvolai? Do you have properties? Did we understand? two properties Are. One, it is very thin, is thin and contains blood vessels With the help of which it is able to do the exchange. Very true, son. Now look at our lungs In addition, there is one at the bottom There is the chest, there is the rib cage, these bones, ribs Cage. and there would be a muscle on the lower side This is what we call diaphragm. What Do you say anything? There is a muscle which we call It is called diagram. this is the muscle you can see You are wondering, this is a diagram. Now you understand The diagram looks like this. Now you inhale. Take a deep breath, son. Breathe In Take. That means the diagram remains normally curved. But When we inhale it becomes straight Is. It becomes flat. and when we excel If you do this then it becomes curved again. And this is the thing to remember. when we inhale If we do that, then what happens? First So the rib cage comes out. Look at the Rib Cage will come out. Besides that our diagram It becomes flat. It becomes absolutely straight. I told you. Apart from that, the chest There is a cavity, that is, the size of the chest It increases mine. And when I'm gone I'll be gone What happens when I do it? in the eggshell which It is a rib, it goes down. what is diagram It happens? It relaxes you. The diagram looks like this remains. If I inhale it will become straight. It will become flat. Ok? is pe mcq It comes. And the chest cavity means the part of the chest The size is there, it gets reduced. Isn't it? Chest The size reduces at the time of egestion. Did you understand this, son? Tell me quickly. Have we understood the whole concept? Is? So let us look at some questions quickly. From. That will give you clarity. gave the Reece's rings of cartilage are present in Throat. What does the ring of cartilage do? Prevent wind pipe from collapsing. That means, what is its function? This is from the collapse Saves it. Lung Always Contain Residual Volume of Air. That means the lung has nothing The volume is always there. when you excel Even after that, you give him a little bit It happens inside. Meaning there remains air. Sari Air Doesn't come out. Why don't you come? Understand. Two Allow Continuous Exchange of Gas and Prevent lung collapse. if all the air is out If she goes away my lung will get compressed. Lung It will collapse. Ok? The next Diaphragm Flats and Rivers Are Lifted Up When we breathe in. It is obvious. Why does this happen? So that the chest size increases So that you can take in more air. Correct Is? The walls of the alveoli contain extensive Network of blood vessels. Why? to exchange CO2 & Oxygen. What is the plan? Alveoli has to give oxygen, has to take CO2. Ok? very nice. Is this what you understood? Let's see the next one. why is it respiratory Pigments needed in multicellular Organism? Variant question. What is respiratory pigment? Hemoglobin. why hemoglobin Is it important within us? because Hemoglobin is used in gas exchange. If you don't have hemoglobin then your There will be no oxygen in the blood. so therefore Hemoglobin is variant. Ok? so which They are multicellular organisms There is a lot of hemoglobin inside, which It is present inside the blood. about this We will also read further in detail when we Transportation will start. Let's go next Question. I will read about it now. Next describe the exchange of gases in Alveoli. How do the alveoli work, son? Exchange of Gases. remember remember remember Do it quickly. how does it work? and why are Alveoli richly supplied with blood vessels? Now See how the alveoli do this? point two Remember the point. each alveoli is surrounded By network of thin-walled blood capillaries. That means there are thin blood capillaries. Ok? Oxygen Present in Inhaled Air Diffuses from Alvalai. That is, what we He brought oxygen and came to our alvalai. And what do the alveoli do? that oxygen Sends it into the blood. and which blood there's CO2, there's carbon dioxide, take that back He calls him to himself from there. Ok? Carbon where is dioxide from deoxygenated blood But does it come? enters the alveoli. what happens then? Time of Alveoli Eggle But it comes out of the alveoli. in the lungs It comes and we ignore it. so this What is the whole thing? There is a process. Memory Keep it is variant. Isn't it? These are repeatedly It has been asked how the alveoli work Is. Ok, this is the respiration of animals That's it. Isn't it? and i missed a line I have a very lovely line that Take me somewhere far away. take me somewhere far away Wherever you smile, that is my destination. hey son read it look behind there is your mother Watch. Read it, read it. The paper is here. next About Respiration in Plant. I did not study poetry. Respiration Inn What is a plant? what is the plant too Do you do respiration? Of course I do. How to do it? hey let's exchange No. I don't do respiration but I do breathing We do. Let's exchange gases. How to do it? Look, first thing, son. I have already explained it with the help of stomata. Ok? Apart from that, remember that there are some pores. The plant has some pores which are called We talk about lenty sales. Their stem which The stem of a plant has some pores in it These are what we call lentil cells. With their help, they exchange gases. Are. Apart from that, with the help of Root also generally Surface of the root. Gases are also removed with the help of root Let's exchange the . Why plant now? Exchanging gases? Two tasks. One So photosynthesis has to be done. second to these also I have to do respiration brother. The energy for them I also have to make it. So this is also respiration do. Ok? now here's a big good An interesting question arises when the day is passing by If it happens then the plant does both the processes Is. Look, it also does photosynthesis, He also does respiration. But as soon as the night If it happens then respiration is necessary to stay alive So, it will have to be done. Isn't it? create energy Will need it. but only at night Can do respiration. No photosynthesis can do it because there is no sunlight. How will photosynthesis happen? So remember that sir The plants which are there during the day Provides oxygen. Why? Because A lot of oxygen is produced in photosynthesis Is. but at night because he only Let's do respiration. and in respiration What would have become of you, son? Remember. CO2 is produced No? Energy H2O CO2? Yes. Because of this, the plant They are releasing CO2 at night. Isn't it? So such a question comes which of the The following statement is true about Respiration in plant? Which of these Is the statement true? So you will read option D. Both photosynthesis and respiration occur in The leave during the day. both things would have been Are. Ok? Also How Do Fishes Do This Breathe? This also becomes a small question. This raises the question of whether fishes or fishing are breathing is the breathing rate that fish have His breathing rate would be higher This is in comparison to animals. Why so? Hey it's simple friend. there is less oxygen in the water So he should drink lots of water again and again so that it can draw oxygen from the water because he also has to do respiration Isn't it right, my friend, it is necessary to do respiration. Ok? very nice. So first remember Fishes use gills. He has a specialized There is an organ. like we have lungs Is. they have gills to absorb Diluted oxygen from the water? Now in this I am telling you this question which comes up. Am. Why Do Aquatic Organisms Have Aquatic Organisms Faster breathing rate? Its a simple answer Is. Because water has less dissolved Oxygen. There's less oxygen, friend. In the water, In comparison to air, one has to breathe again and again I will have to do it, friend. So remember them to be There is a specialized organ which we call Gill says. let's go here now Respiration stops. and let us START. The next topic which is Transportation. Now we'll talk about our hearts from the heart. Let's speak what's in our hearts. I I will just drink water. Let us go. Now you are thinking You might be wondering what this transportation is? Look, transportation is also a life process. So far we have studied two life processes. One was nutrition and one was respiration. One Let us summarize it once. what is nutrition Was? in which we had to eat food and Energy had to be generated. How? We Start with the mouth. What was in the mouth? Salivary amylase. very nice. esophagus What came out of it? Peristaltic With the movement the food reached the stomach. came again Stomach. What was near the stomach? three brothers All three are catastrophes. HCl, mucus and pepsin. very nice. Remember the work of all three. His Besides, the food was going down again. then He meets two goons. First thug Who was it? One was liver, one was pancreas. The liver does two things. The liver produces bile juice I got it secret and did two things. I remember What? what did you do? Emulsification of Fat And the food was made alkaline. That is, basic created. After that this goon shot another The goon said to the pancreas that now I You will have to do three things. So he used three enzymes Had to release it. if you remember trypsin, lipase and pancreatic Amylase. Then the food used to go to Small What was there where in the intestine? Vilay Finger like structure. he to eat Used to absorb it. and what was waste From the Large Intestine to the Large Intestine In the anus. This was human nutrition. And Then we read about respiration. In Respiration Remember the game. Where is the game from? your lungs Of. What happens inside the lungs? Alveoli. What do alveoli contain? Blood vessels. And what is inside the blood? hemoglobin which is respiratory Pigments. What does he do? to the oxygen He calls me to himself. with the help of which your The deoxygenated blood is returned It becomes oxygenated. so completed this This is the whole story so far. Now we move on There is transportation. Next Life Look at the process inside transportation as well No, there are three things. there are three brothers here Too. Which brothers? first of all if brother's If I talk about it, it is blood. blood is a Tissue. Blood is a connective tissue. Correct Is? The most important thing to transport Who is it? Blood. In addition, blood vessels From which this blood is going to go. And The heart comes last. Isn't it? and the heart said this I have said it from my heart. The heart said this to the heart. Yours is being cut again. Ok? So What is the function of the heart? The heart's job is to pump There is nothing else to do. Oh brother I didn't I gave my heart and did it. not a work of the heart Have to pump. If you gave your heart to someone Then you are also finished. Totally upset. So the most First, what is transportation? Transportation in Living Organisms Refers to the process of moving food, Water, Oxygen and Other Essential Materials Two different parts of the body. Different Taking everything to us in parts Is. Who will work? these three brothers here There are people who will work. heart is a pumping Organ son. Don't give your heart to anyone. and if Even if you have given your heart to someone, take a look at it. You You are considering her as Aayushi. what does he know Your friend Ayush sitting next to you should go out. Who knows, he might create a fake ID and chat with you. doing. So find out as well. Ok? Yes. So what is the work? Very nice hearted person. Heart We will read about it in detail. Most of the Is. Let's start first with blood. Blood what is it son? look blood type It is connective tissue. In the ninth class you You must have read it also. oh ho in ninth class You did not study. No problem. Correct Is? It is a type of connective tissue. Its colour is red. It is red in colour. Why? because it has a respiratory It is a pigment whose story we have heard a lot about It has been taken. what is his name? Respiratory Pigment called hemoglobin. Ok? Which is It is found inside the red blood cells. So Look at the blood before explaining its function The functions of will become clear to you. If If you understand the parts of blood. Basically, How many parts does blood have? Three There are parts. what is the first part Is? Blood plasma. That is, the liquid part isn't it inside the blood due to which the blood moves What blood plasma can do is this. Whatever its color is, its color is like that It is a little pale yellow type. And What is inside it? Fluid Medium Caring Nutrients. That means this Nutrient, waste, everything is inside it is inside the plasma. Ok? Now come on Blood cells i.e. blood corpus cells. Two There are type A blood corpus cells. To you RBC will also know. Not RCB but RBC. Ok? RCB fans yes WBC. Correct Is? So one is a red blood cell and the other is There are white blood cells. Look at the red blood cells What does it do? We have heard talks about it that it contains hemoglobin and What does hemoglobin do? of oxygen It is useful in transport. Oxygen and carbon dioxide both It is useful in transportation. Very Excellent. Next comes the white blood cell. These He is a warrior in a way. What does he do? Protects our body. So Provides immunity boosters Antibodies against disease. fight the disease It is useful for. And there is one more thing, the third thing Which are platelets. Variant. Never hurt If it had happened then the injury would have healed in a few days Is. Why does it fill up? Due To Platelets. That is, what are these platelets? Helps in blood clotting. That means injury somewhere It seems that the clotting that happens is this I am getting platelets done. So this is blood All the work is there. now can you function yourself Can't you write about blood? functions of blood You can write it yourself now. what is the first job Is the blood done? Look, the first job is done What? To provide transportation. Whose Transport? Oxygen Nutrients Carbon dioxide. very nice. Second low oxygenation, because the blood has It contains RBC. Next to RBC Hemoglobin. hemoglobin binds oxygen Takes it. So the oxygen supply is the most Blood plays an important role in it. Ok? Blood is very important. very nice. Next defense. That means if any disease comes Who will fight him? The WBC will fight. So It is also providing immunity. The next one is Temperature regulation. of our body Blood also regulates the temperature He does. end clotting. I also saw clotting I told you. blood platelets Let's do the clotting. these five point son Remember this. repeatedly asked in the paper Function of blood. And the kids don't remember would stay. But you will remember it. Why? Because you have studied under PK Bhaiya No. Okay, this was about blood. Is it coming now? Blood vessels. Three Types There are blood vessels. What are vessels? Tube. There are three types of tubes. there would have been one Yes, arteries, is there just one? Vance and a There are capillaries. Let us understand one by one. Look, I am telling you a trick to remember it, son. of. Arteries means A is coming in it. and a There is another word from this. Away away away. i.e These arteries carry the blood from the heart Will always take you far away. That means this blood Where will you take me? Dil Se Ave Door Leke Will go. Vance does the opposite. Vance They take us towards it. towards the heart They take it away. What are capillaries? These Connects arteries and veins. i.e This is the middle path. This connects the two. Ok? very nice. Ok? So this is you You must know Carry Blood Away from the Heart. Carry blood toward the heart. Ok Brother. The next thing to remember is arteries always Carry oxygenated blood. but one exception It's like he's not in class. a child who is sitting on the back bench but when When the result comes, everyone gets shocked. Hey how did he top it? Isn't it? Yes. you might as well. So similarly here is a There is an exception. Always oxygenated though Carries blood. but an exception came Which goes to the pulmonary artery. Pulmonary artery. very nice. Wayne also Always carries deoxygenated blood. That means dirty blood, that is, blood containing CO2. butt here But there is an exception, the same thing. Pulmonary Wayne. Ok? very nice. and the capillaries Carries both. Ok? Meaning Blood of both oxygenated and deoxygenated Carries the . very nice. Now look at what There is pressure, son. Pressure in the arteries. It is very high. Blood pressure. Why? Because arteries carry blood away from the heart We are going. And how does the heart beat? Dhak Dhak Dhak dhak dhak-dhak. Isn't it? So when it flows the blood like this You are taking blood with a lot of pressure It comes. The pressure is high here. Here, take it Take it there too. Ok? remember the thickness of the wall To keep the thickness of the artery wall thicker Is. This is thick. It is thin and it So it is very thin. now why is this thick It happens? Because it causes high blood pressure Have to carry it. If it becomes thin it will burst I will go brother. If the pipe is thin it can burst Isn't it? Yes very nice. The next thing is Valve. Remember Valves Are Only Present In ven. Valves are present in the vein. Now you will ask brother what does the valve do? Questions have been asked repeatedly in this. See son, this is your van. Ok? Now such valves would not be present in the vein Are. Why do these happen? accept the blood From your feet to your heart. now like this It is also possible that the blood may go down That means the blood will flow in the reverse direction and your heart will Couldn’t even reach it. This will cause your death will go. So to prevent that from happening Valves are fitted. as soon as the blood comes up This is where the blood gets locked. then further It goes here it can get locked. i.e That blood can't go down. so what is the valve are you doing it? Preventing back flow Are. And this was the question asked. Valve In this case, it helps in preventing back flow of The Blood. Please mark the variant star. It has been repeatedly asked what the valves do Are? Why are they present in veins? Because these prevent back flow. Back They stop me from going. Very true, son. Correct Is? did you understand the function? what do arteries do Are you? In the entire body away from the heart. and this Blood is being brought from the whole body to the heart To. And the poor cafeterias are connected in the middle are doing it. Is it ok brother? these things to us It has been cleared. Isn't it? now over here Some useful things have been written that the biggest The artery of our body is iota. These There are many more names to come, so remember them. Take. Ok? Iota. The largest artery is is iota. Ok? the only artery that caries Deoxygenated blood. The only artery that It carries deoxygenated blood Pulmonary artery. similarly the largest vein The vein in your body is called Venakava. What? vena cava. and the only van that Who carries oxygenated blood is it c? Pulmonary vein. these are in mcqs Four things are asked. so you remember Needed Now let's move on to the functioning of Heart. We speak our heart out from the heart. Now let's come to a very important thing in this You have to understand. How does the heart work? Isn't it? How many chambers does the heart have? This diagram is a must. Isn't it? Do you ever ask about it? Are. These days it is being asked less but you can ask Are. I will show you a simple diagram Let me explain. Look, the first one is the heart. Heart Brother, it has four chambers. Four Chambers make it. Ok? a look at the left side The right side has to be looked at like this, son left side right side left side right The side is fine, this is the left, this is the right, like this I don't want to see that brother this is right this is It is left no no no it has to be seen like this there is left and right, okay so there is one The left side is one, the right side is now this There is someone above, it has two names either it is called atrium or it is called It is called oracle, it has two names and it we say what we call it ventricle what do we call this they say ventricle okay this auricle or atrium or ventricle here also auricle or Atrium or ventricle what would this be? Left Say. Left atrium Left ventricle. Right atrium Right ventricle. Now watch the game Where does it happen from? Understand this completely Son. Explaining the flow chart with the help of a story Give. You will never forget. 5 to 10 minutes Will take. Look, this is your lung. Assume this I am lame. What does Lung do, son? Lung Kya does it? Makes the blood oxygenated. yes and no? Yes. So oxygenated blood will come. The blood has to be brought towards the heart. Ok Brother. very nice. then blood flows towards the heart It is first on the left side. Left Side Where does the blood come from? From the lung. Ye Lung Is. Where did the blood come from the lung? Towards the heart. Entry is on the left side. Ok? In the left atrium. That means it is left in the atrium. Then comes the left ventricle In. Meaning this is how the blood goes down. and his After this the blood comes out from here, get out from here It goes into the whole body. That means here There will be a body. So now that blood of yours is going hey son it is going throughout my whole body Is. It is going inside your body. Ok? Now what happened to the body? Respiration took place, Carbon dioxide was released. Now the blood is back has become deoxygenated. Now this Deoxygenated blood right? Do you know where this is Will he come? It will come back from here now, i.e. right in the atrium. will go right from the right atrium in the ventricle. and now from the right ventricle Where will it go back to? this will go limp Near. And this cycle will keep moving. Now the naming here is very It is important. I'll show you the nomenclature Am. First of all look at this and understand the concept You went, right? Oxygenated blood in the left side and what comes on the right side? Deoxygenated blood arrives. came from the lungs Body to heart and back to heart. Awesome lunge. Ok? Did you understand this? Now I will show you a very nice diagram With this help you can read the whole story easily I will explain it to you. Look who brings the blood? We will have to remember these names. Obviously C The thing is. who takes the blood from the heart into the heart Will he come? Who brings blood to the heart? Wayne I will bring it. Which van will bring it? Pulmonary vein. Now from here the left ventricle Who will take the blood from the body? that would be One artery is the iota. then here Where will the blood come back from? Right Atrium In. Who will bring it? He will bring Veena To move a horse around in a circle. A type of wen. and then blood from here it will go back to the lung which It will take the pulmonary artery. Now this brother Nobody remembers. I have a trick Is. Now he has a trick, brother. See Let's see the trick, son. a story for you I have to remember this. She was a badminton player. P V Sindhu. You must know. So look PV Sindhu has won no medal and Now he cannot make video calls to his family members I have to do it and show it to you, look papa and mummy I have not won a medal, so how is that We will do it, see, PV Sindhu ji said come Ayo is not said like in South, Ayo what did he say ayo what did he say ayo Please make me a VC or video call And to whom did he tell this? PA is PA, not Personal Assistant etc. yes so I told him that I told the PA that Friend PV Sindhu called me video Make a call. Who did you tell? from your PA spoke. if you remember this Your heart topic is over. Address why is it? Where is the blood going from the lungs Is? In the heart. Who is bringing it? P.V. What does PV mean? Pulmonary vein. To all First. Ok? Now blood from the left ventricle It is going into the body. Who is taking it? Iota. Who? Iota. What is iota? Ayo. Ayo means iota. Then he said video Call. Now see who is bringing back the blood from the body In the right atrium is the Venacava Veena kava vinakava ie VC VC very good And where is that blood going back to the lungs? who is going to take the pulmonary Artery means P A then means from story now Your whole heart could be destroyed what did PV Sindhu say What should I do? Make a video call. Who did I tell? I just told my PA through the story You should remember all the names now. Did you understand it? very nice. if it made sense So tell me once. Now here are some pointers Yes, son, you will have to remember this. The first pointer is this middle wall We speak of septum. What is this? These There is a septum. What do we call this dividing ball? Do you say it son? Septum speaks. if you You must be able to see it clearly. Ok? His Apart from this, I have given you the complete flow I told you. Remember one thing. vena cava na Look, there are two entry points to Vena Cava. One is from the lower body. Veena came from here Kawa and one from the upper body. That means one is the upper Body one bottom body. The blood from both where does he come from? We Take Minakawa It comes and goes into the right atrium Is. Is this clear? very nice. Apart from this there are some differences son which you This should be remembered. What are those differences? first of all the atrium and ventricle Difference. Ok? Atrium and ventricle. Well, what is the size of your heart? You know your fist this much. It is just so It happens to you. Yes. your heart was so big Is. But it does such important work, right? so Don't give your heart to anyone. Ok? Heart is a must. Don't give your heart to anyone. Yes, its okay. understand in atrium ventricle This is the upper chamber. This would be the lower chamber Is. well the walls of the atrium Son, they are thin. While the ventricle's The walls are thick. Why? You can also see it. Look at the atrium wall So how thin are you? how many butt ventricles She is fat. Why? because the ventricle has To pump blood. It has to pump blood, right? Under high pressure. So that's why her walls are thick Should be. Otherwise the same situation will occur. will burst Heart and what else? Ok? what do they do Son? The atrium receives the blood and What do the ventricles always do? pumping up Are. Pumps the blood. Ok? it This thing is very important. oxygenated Where does deoxygenated blood go? These It is very important. I hope this diagram You must have understood the whole thing. came or Didn't you come? This brings up a lot of questions, son. Remember this. Oxygenated in the Left What did I say? Left Atrium, ventricle, right back from body body Atrium, right ventricle, lungs. on lungs your blood comes back from being deoxygenated gets converted into oxygenated Is. Ok? now if you can see here But there are four chambers. So the question arises that Why do we have four chambers? Our four Why are there chambers? I will tell you the answer to this What is. Look, it is written here also. Why are there four chambers? to prevent Mixing of Oxygenated End Deoxygenated Blood Will Be More Oxygenated Supply to the body organs in a better way. look we're a type of multicellular There are organisms. we need a lot of energy Brother. so if our oxygenated If deoxygenated blood gets mixed then Do you know what will happen? oxygen supply is It will not be good inside the body. so There are four chambers. Why? so that look you'll be oxygenated here and Deoxygenated will be here. So be divided Went. oxygenated deoxygenated divide be Went. This increases our efficiency. OK brother very good. In addition, if If you have noticed, there are two bicycles here. I have two bicycles, son. Which is a bicycle Is? Look carefully here, son. One There is a bicycle. look the double cycle is running Here. There is double circulation. we have double There is circulation. How? A bicycle is lame from heart to lung and back from heart to lung In. you can see from lung to heart and From heart to lungs. a bicycle. Second What is the cycle, son? From the heart to the body And from the body to the heart. i.e. there are two I have a bicycle brother. Yes. That is why we speak Humans have double circulation. So this is the first This bicycle that you can see is long to We call this heart to lung pulmonary circuit pulmonary circuit and these You can see this, we call it The systemic circuit is also written here I will explain it to you in detail First, look at what is the pulmonary circuit What is the pulmonary circuit where blood flows from heart to lung and back okay one is this The first one is done, apart from that there is a systemic We call it circulation or systemic circuit what is that blood flows from heart part to the rest of the body and Returns. So what is this? This became the second Circulation. Now these two circulations are important Why does it happen? over and over again your paper You are going to see the question inside also. Son Today I am telling you that the question will come in the paper. Why does double circulation exist? What is the answer? Let's see. Now what happens with double circulation Is? Keeps the oxygen rich blood separated From oxygen poor blood. Insurances Efficient supply of oxygen to the body maintain high pressure in the systemic Circulation for proper distribution. Now What is happening with this? One is oxygen The supply is increasing. Second, every one of our bodies are able to get blood to its parts, Oxygen is available. That is, respiration It is possible. It is because of oxygen Respiration occurs. Yes. So because of this Double circulation is too much for us son It becomes important. ok sir. What Did you understand? Here I have some three I also wrote down the points that why is it Necessary to have four chambers. I….to you It is also written here that the first one has arrived to prevent mixing of blood For. Ensure efficiency of oxygen Supply. Second point son remember these Take. The Third Essential for Warm Blooded Animals. Let me explain this. Now look at some There are animals that are cold blooded Are. Some are warm-blooded. Difference What is? We measure our body temperature Can change. The blood that we have is ours Can control body temperature. Isn't it? What do we call this? This we They call it warm blooded animals. which we Are. There are many more organisms. Whereas Some organisms are cold blooded. whose blood cannot control their temperature He who can do this is called cold blooded. So All the warm-blooded animals No, the four chambers are very important for them And there is double circulation. If this is not If it happens then they will not be able to survive. Correct Is? So a four chamber heart is necessary. As such Son, the real heart is visible. take a look today I also showed you his heart. Isn't it? No child should come writing this in the answer that Brother, why are there four chambers? Four Chambers Bhaiya boys boys four chamber address why do they happen? One has Riya, one has I have Aayushi, I have Sunaina, I have It is Neha. No son, don't write this. Four Understand the logic of the chamber. Ok? Which Which components of blood help in clotting does it son? Platelets do. Very Excellent. next v of the following statement is this true about human heart? Of these is it true son? Very good question. Has been asked repeatedly. Tell me the first statement right atrium receives oxygenated blood Is. The left one takes oxygenated. Right One that's deoxygenated. Isn't it? you know this how can you remember? she comes a book Isn't it RD Sharma? so you remember should always be on RD i.e. right It will arrive deoxygenated. So this is wrong Went. Let's move ahead. Left Atrium Transverse Oxygenated Blood to the Left Ventricle. very nice. This is absolutely correct Is. Left Atrium to Left Ventricle It transfers and from there, the whole body I go in. Who takes it? Iota. Ok? Let's see the next one. Right Atrium Receives deoxygenated blood through vein Kaaba from upper and lower part. is this Is this correct? Look at the right atrium. Memorize the right atrium diagram. Right what is the atrium that carries deoxygenated blood Who receives it? He does it. From where? does he receive it? vena cava. anytime If you are confused, remember this. P V Sindhu What? PV Sindhu made a video call Get it done. Whom did you tell? I told my PA. Correct Is? So this statement is also absolutely correct. Let's see the last one. Left Atrium Transfers oxygenated blood to iota. oh no bhaiya left atrium left How will Atrium transfer to Iota? The left ventricle transfers. so this It went wrong. So option B and C should come That is option C. very nice. Look very much This was a good question. Next Assertion is of Reasoning Many questions are being asked these days. See The Wall The Wall of Atria. atria ie Brother, that is what is called atrium. Ok? A Wall The atria are thicker than those of the ventricles. No. No. The wall of the atrium is thin. The ventricle is thick. Because The ventricle has to push. So in this So statement A itself is wrong. So its The correct option will be D. Isn't it? if you If you have done Assertion Reasoning then you would know There must be an answer as to why it is coming out as D. If If you haven't done it then practice it. in the papers It is being asked nowadays. next question level di Part A and B in the Diagram of the Human Heart. Look brother, you have to see this. These It is left. This is the left. This is right. This way Look at yourself, son. Isn't it? is this the left or is it right? Look, this is the upper part on the left Of. So what is this? Left atrium or The left auricle can also speak. and what is this Is? Right. Right ventricular. Very Excellent. Right ventricle. very nice. Correct Is? Next Differentiate Between Pulmonary Artery and pulmonary vein based on the type of blood they carry and direction of blood they Flow. It is just a question of differentiation. Between whom? Pulmonary Artery End Pulmonary vein. Look where the pulmonary artery is But did she come? That artery which is the lung From heart to lungs. look he comes in last PA. PA comes last. that is, from the heart It is the PA's job to pump blood into the lungs. And what does PV do? Pulmonary Vein Vo It brings it inside the heart. Yes. So that means What is? What does the pulmonary artery do? Deoxygenated blood. and what is the pulmonary vein does it? carries oxygenated blood Is. It takes the heart to the lungs and this It takes the lung to the heart. Did you understand? fun Came? Is it going through your mind, or did it just happen? Brother, what are you teaching me? read something like this Whatever is understandable. Why am I not able to understand anything? Ok? It will come, it will come. This is a little It's something that needs practice. when you Because when you read it for the first time, you don't remember the name. They don't happen. Practice the name a little. next why are the walls of the ventricle thicker than The Wall of Atrium? I just told you the the walls of the ventricle are thicker than the walls Off atrium? because ventricles have to pump Blood with the greater force. because of this I told him he needed to pump it. Ok? Why Do Arteries Have to Be Thick and Elastic Wall? Why are the walls of arteries thick? Because arteries have to pump? the blood that pumps He has come, who will take him away from my heart Used to be? Who's taking away? Arteries. So that means it is high pressure blood. This Because what is their wall? Is? It is thick. It is also written here Due to high pressure. Because of high pressure The main reason remains. now let's look at the next one There is another topic. Like I told you not to We have four chambers in our body. But everybody There are not four chambers. like if I talk If I look at the fishes then look carefully. Fishes We also call it passage. Now this which These are fishes, right? These have a two chamber heart. She carries it. Yes. so what's inside them It happens? There are only and only single Circulation occurs. and these are what we call He is cold blooded. Isn't it? Cold blooded. Ephebeians besides him. Ephebeians you know like your turter yeah A photo has also been made. See for yourself. Your Looks like a friend. look at this too Look, it looks like a friend. Yes. So It has three chambers. So this double Unable to circulate. Incomplete Double The circulation is doing this and this too He is cold blooded. Is it ok brother? Temperature cannot regulate. Reptiles that They also have three chambers like Crocodiles and these are also cold blooded And this is also completely double circulation I can't do it. but birds i.e. abs and Mammals that is us. Birds means abs and There are two types of mammals: Those who have what? have four chambers Are. Do a complete double circulation. And what happen? Warm-blooded. That means this You can control your temperature. Correct Is? So a question was asked here Why does more chamber in the heart matter in Evolution? this is a bit high level The question is asked. Evolution, that is As we have evolved. So when we if we have evolved then our bodies are inside it Why are there four chambers inside? So You didn't have to think anything about this. Its You had to write the same answer inside. i.e Why four chambers exist. why? speak to Ensure supply of oxygen. Oxygen Body Supply will continue. In all the parts The supply will continue to be good. Isn't it? So that is what you had to write in it. other than that Warm blooded animals require Is. Isn't it? take your temperature if they That is what we have to control. and besides that oxygenated and deoxygenated blood To keep it separate. Yes very nice. These It happened, right? Ok? ok the one in the middle The name of the wall is septum. which is between the heart There is a wall there, it is septum septum. So That is why the blood from here cannot go here. The kids must be thinking brother here Why are you not going? there's a wall in between Which we call septum. ok sir. very nice. Now let's come to the next system Which is the lymphatic system. I drink water I will take it. Now what is this lymphatic system? It happens? Please tell me this, brother. See The lymphatic system is a slightly different type There is a system which takes a little time to understand It is complicated. But why should I wear one? Ke bhaiya is here? See what happens? First understand what is lymph? Lymph. Lymph is called as tissue fluid. i.e The tissue contains a fluid. now you What do you want to understand inside the story? Capillaries Remember capillaries? Yes. Which is Let's connect the two. So these capillaries what are these, they carry blood etc. They have been here and there. but what here Something happens by leaking substances Let's go. Isn't it? Leaks happen. As Some substances got leaked. Look Formed when plasma proteins and some Blood cells escape. Escape means leak through The Pores of Capillary Walls. i.e. capillary Some substances leaked from the wall. Anywhere, pretend I had a tissue in my body Inside. A capillary was going into it. This substance leaked from him. Isn't it? So What are many of these substances? They get leaked accidentally. Into Intracellular space. i.e. the one between the cells that there are species among them like this Substances get leaked. Ok? So The substance which is formed there, which Fluid is formed and we call that fluid There is lymph. So how was the lymph generated, son? Lymph generated due to leakage. then lymph Nothing is there When capillaries leak When things go away, lymph is formed. So Lymph is a colorless fluid. remember this There is no color and very little inside it Contains protein. So when the blood was going Isn't it so that things have leaked out because of the capillaries From. Now what things got leaked? anytime RBCs do not leak. RBC is important. Isn't it? Because it has hemoglobin in it. Does not leak. but wbc never loads what happens? It gets leaked. Ok? So what happened here is that our tissues It leaked into the tissues. and a fluid It was formed and its name was Lymph. Now this lymph There is WBC in it too, a lot All the proteins are also there. So he gets the blood back I will have to bring it in. So who's back in the blood? Will you bring it? The lymphatic system will bring it. So That is, the lymphatic system carries this thing all the way through. pulls it and comes back to the blood Aaja aaja and throws it in the blood. This is the lymphatic system and nothing else comes. Look brother these are such lymphatics that you You see it's completely green in colour, right? There is a complete lymphatic system. Lymph wherever What happens if they are produced? They have a tube called lymph vessels. Lymph What do vessels do? pulling them and then puts it back into the blood Are. Ok? you can also read it here yes. Lymph flow into lymphatic capillaries. It has capillaries. So this lymph which Colorless fluid collected. remember Where does that colorless thing come in? Capillaries It comes in. which joints to form Larger lymph vessels. then it travels into the lymph vessels It reaches. this vessel finally opened into Larger vein. That means they went into the van. Reconnecting the blood stream. from back It has come into the blood. It's ok brother. Joe Leakes It happened and came back. Now it's okay, now it's okay. That is, this lymphatic system is only and only To prevent leakage. Ok? Now What is its function? Function too many times I have been asked, son. what are the function of Lymph? Look, the first function is clear. What? Transport of Digested and Absorbed fat from intestine to blood. That is, whatever digested food etc. is The leak has also become weak, it needs blood again I have to bring it. The first thing is this This thing is clear. Look for another job Drain access fluid from tissue. i.e what happens sometimes with tissues A lot of water and some fluid gets filled inside. So the fluid that is filled in excess It comes with the lymph and that too with the blood Comes inside. like any harm to the tissue No. Don't get hurt. Ok? then access The off fluid also comes back into the blood goes. Lymph contains lymphocytes. lymphocyte Nothing happens. What is WBC? White blood cell. and what are white blood cells Do you do it son? Gives protection. So Does lymph have another function? defend the Body against infection. That means three lymph nodes Work. One is preventing infection Is. He is stopping us, protecting us. Second, it brings everything back into the blood Used to be. Third, whatever access remains, access of fluid in tissues, also Puts it back into the blood. Isn't it? It is very dangerous brother, it is lymph, it is very dangerous Son, it is important in life. Ok? Bus You will remember these three functions as well, right? It will be enough for you son. Its Let's see the question. I asked what is it? Which of the following is not a function of lymphatic System? What is not a function? no is written Son. transport of digested fat into From intestine. This is it. this function is Is. Return of access tissue fluid. These There is also a function brother. Oxygen transport. Oxygen has no use for this. Oxygen can't come without hemoglobin Not there. hemoglobin for oxygen It is necessary. So here comes option C. Ok? This is not work. Let's talk now Transportation of these plants. Son How does transportation take place in plants? Understand. The plant is also doing transportation. How is he doing? There are two ways. and this You read it in ninth. But I know You did not study it in ninth. I know yes friend. I am able to understand. Something No. So there are two types. One is the xylem. One There is phloem. Had read. There were tissues. What does the xylem do? water and mineral co Transports. phloem food Transports. This difference is repeated Asked about xylem and phloem. See for yourself. See what the xylem does? Conduct Water End Minerals from root to leaf. i.e. from root to leaf I bring it. What does phloem do? Conduct food from leaf to all parts. i.e Where is the food prepared? It is formed in the leaves. photosynthesis and reaches the whole body Is. Ok? Second. Good Xylem Na Mainly It is made of dead elements. did you read Which cells are present in xylem? So these are some cells. if you remember the You can, but it is not asked much. Trackyard, Vessels, Xylem, Parenchyma end xylem fibers. just xylem The parenchyma is alive inside it. Balance What are all three of these? Dead There are. Because of this, we call it xylem. It is composed of mainly dead elements. Whereas It is the opposite of phloem. What is phloem? Phloem is made up of mostly living things. Like there are four inside it also. Phloem fibres, Sieve tubes, Companion cells and phloem parenchyma. Only one of these He is dead. Who? These are phloem fibers. These Dead remains. The rest of it would be made up of living Is. Now a big difference is coming. See Xylem Transport in Unidirection So look at how the xylem transports it. just above the root now that right left up down He will not be able to do it in one direction but this phloem is bye It is directional because food is being produced from the leaf Now the food will go up as well as down from the leaf if it goes in both directions then that means Transport in phloem is bidirectional Remember this has been asked many times The difference is very important, this difference The question about the table is also asked again and again It seems that there is trans transportation How are you? Understand. Let me talk about xylem. There are two modes of transport in xylem Of. One is root pressure. See It is the root of the plant. What is outside the root? Say. What's outside the root, son? of the root There is water outside. It is obvious. In the root There is less water here and there is more water there. you have did you read it? Osmosis, High Pressure to Low Pressure. So where there is more water what will happen from this? The water will come in. Obviously That's right. So it is a very easy process Which we call root pressure. gets upset is in the water and it draws the water in Due to osmosis high pressure to low pressure The water moves in. Second Process It is very important and you have read it. Just read it a while ago. Yes Remember transpiration? what is transpiration Did it happen? water vapour from the leaves used to fly in the form of. Did you remember? Now Do you know what happens? now in the leaves What happened? Say. water evaporates in the leaves Went. That means what happened to the leaf here now? Is? There is low pressure on the leaf. And what's down? What's in the root? Hi There is pressure. then why water from bottom to top Will he come? because high pressure to low pressure I will move. i.e. transpiration Nor is it for transporting water It is necessary. If transpiration does not occur then The water will not be able to rise up. understand this thing To? Yes. Ok? So I have given you two ways Tell me. First of all, what did I tell you? Look son, xylem tissue transports water and Minerals from Root to Leaves. Water Enters Root by Osmosis. Look, I told you In osmosis the end moves upward through xylem Vessel. Ok? it moves upward through xylem Vessel. This upward movement is called ascent of sap. That is, this water which is above the root Do you want to know this process, we call it Ascent of Sepp. sometimes it is asked What is ascent of sap? movement of water from root to upward direction by Xylem. It is called ascent of sap. Now look at the two There is a reason. What? One is root pressure. I told you the root pulls and there is a Transpiration bridge. transpiration bridge which that I am telling you. Transpiration Do you know what happens? The Loss Of Water in the form of water vapor by Stomata. Isn't it? so right there Transpiration pull is taking place. Why? Because what is coming there? Take Pressure. There is high pressure below. so up It moves. Ok? So remember this one The work is pulling water upward. and one more job You have already read it. access to water Removes it. Isn't it? access to water Removes transpiration. But It is also used to bring up water. Very important role in pulling water upward is of transpiration. Is it ok brother? Understanding Am I in? very nice. Now let's talk of phloem. How does phloem work son? So see phloem food by the help of means Phloem is what transports food from both leaves to the Takes you in the direction. Ok? And What do we call that process? Translocation. what do you say son? Trans Location. Anytime someone asks what is Translocation? So there is nothing. The Movement of food from leaf to other parts of the Plant by the help of phloem is called Translocation. Ok? So what to eat This is movement, we call it translocation Are. Ok? Phloem Transport prepared food from leaves to the other Part of the plant. this process is called Translocation. Ok? The energy inside it is required because every I have to go in that direction. then it requires Energy. Did you understand? This is what is in the plant. One is xylem, one is phloem. Xylem Mineral Is. And what is he doing? yes, its doing this yes food. very nice. Ok, now the question Let's see. which of the following statement Correctly Explain the Transpiration Pool Off the plant? Which of these statements Telling about transpiration bridge Is? So if you look at this, what is there in it? Read option B once. it is caused by Evaporation of water from leaf surface pulling Water up through the xylem. This is what happens. The water on top evaporates Is. There is low pressure here. yes, very much Correct. Wow friend brother. Ok. I understood this. next. the process in which transport of Soluble Products of Photosynthesis Tech The place is known. Say. Say. Digested Food How is transportation done? what to him Do you say anything? Just read it. Translocation. Is this so? You have become smart. Good This is a very lovely question. About this one Think about it and tell me. in this question if you If you look carefully, you will see the diagram Have to focus. this diagram, who is this What type of process is he describing? If you If you look carefully at this diagram, you will see, What happened? There was a leaf up here. From the Leaf Look at the water vapor and then look from the root The water started moving upwards. By moving water upward with the help of transpiration Used to be. This is the process we were talking about Transpiration bridge. that is, the bridge which It seems to be due to transpiration. Correct Is? So what can we say to this? This we can call the process Transpiration. Ok? a bridge was created This is due to transpiration. very nice. Now we are moving on to the last topic of this chapter Which is son excretion. Excretion is a must. Ok? question from this too coming. and look i haven't seen that There are two types of students. one that Students who are very confused. and other students who know that What they should not do in life. Such as They know that they don't want to study. But you have to study son, exams are coming If you have gone then you will become the first type of student Go, even if you are confused, you have to study Friend, there were some children in our school also those who had clarity that brother we will study we won't do it, come on what will be the exception Hey son, look, what we read earlier is Ision had undigested food removed what is excretion look excretion is the biological process of removing harmful metabolic waste like urea and uric Acid from the body, that is, as many Urea nitrogen is a harmful substance We will remove all the compounds. Correct Is? From our body. How does it happen now, son? This diagram is this diagram again and again Comes to make it. you remember this Take. It is very simple. where the kidney is located Son? The kidney is located here. people think yes, it happens here. No, it happens here. Back The kidney is on the side. Ok? So these two are bean like structures which are These are the kidneys. Our body has two kidneys Inside. So what happens is that blood comes out Here. Isn't it? Blood came here. Correct Is? Now who brings the blood? then remember Keep the renal artery. there are two renal arteries Left and right. So the one on the left kidney It will take you to what is called the left renal artery And the one who will take it to the right one, It will be called right renal artery. okay brother? There was bleeding in the artery. Now there's dirt in this blood Is. Now the dirt inside the kidney will be cleaned. all the germs worms germs ball I have been. Nitrogen Compounds and so on Will be filtered. how are his We will talk about it now. Ok? Then What will happen? The blood which has been cleaned. that blood will go back to top by the help of Renal vein. That means two renal veins and one There will be a left renal vein and there will be a right renal vein Wayne. Ok? Now the waste that is left is access of water nitrogen compounds all these You see two pipes. these pipes There are ureters. What do you say to them? Ureter. Ok? One is the left ureter. One is the right ureter. Ok? with the help of ureter It comes here. and this is your urinary Bladder. Inside the urinary bladder, you It is your urine, do you store it? and take it out with the help of urethra You give it. Ok? So what is flow? kidney. There was bleeding in the kidney. Made a mess. dirt Ureter, urinary bladder, urethra. Below what did you do? As much as you want You call it urine, it contains nitrogen There are compounds. access of water hota Is. A lot of things happen. Ok? So How does remembering happen? what the kidney does Is? Filter nitrogenous waste. First job What does the ureter do? carry urine from Kidney to bladder. The bladder stores it. Stores urine and releases urine out. Who? Urethra. With the help of urethra, you can pass urine You throw it out. Now everybody has one thing on their mind brother you must be wondering this diagram so we I will remember it. Not that difficult diagram Not there. everything is clear in this diagram Inside. Well, remember one more thing in this. These What you see is this big one, This is iota. What is this? Iota. to you Do you remember what comes from the heart? from the heart what will come? Iota comes from the heart. so this Iota is the division of renal arteries Inside. These two little ones are going, Rinal There are arteries. The bigger one is iota. and who This bigger one is taking it back, right? Do you know who it is? He asked who is it? this is veena To move a horse around in a circle. Yes. So I brought Iota. be divided Went into the renal artery. Cleanliness in this Hui. Where did the pure blood go back? Where will Veena Kava take me? Towards the heart. Where will it take your heart? Right. Right. Right. Very true. Okay, now I understand this. Now Let's talk about what is going on with the kidney brother Is it special? What is happening in the kidney? So Nephron is present in the kidney. what is a nephron Is? Nephron is a structural and functional Unit of Kidney. That is, the most Do you know the important thing in one kidney There are millions of nephrons. and this Nephrons perform a type of filtration function We do. responsible for filtration of Blood. How to do it? There is a story. Three This is Step's story. This is a diagram brother You should try to remember. if asked I have been there very few times. but look try it You can. If you can make it then make it. Ok? What am I saying? don't do all these things Make it. Just this yellow portion You can see it, right? Focus on it. These You can see the yellow portion right? You just have to do it like this on this portion Have to focus. Isn't it? This one is yellow There is a complete portion. Just this to you The force has to be focused. Ok? Now I Let me explain how. Look, there is blood. Three There are stories, it is in three parts. Means three There are steps. I am telling you How the nephron filters blood. One The kidney contains millions of nephrons. One How does a nephron work? that I give you I am going to tell you. Ok? will come first Blood. The blood came in, came in, came in, Came inside. Think of it as if the blood spoke You will not welcome us. So the nephron Did you say you will do it? do? Absolutely do. So I gave him a capsule to eat For. Gave the capsule. To imagine. For him Gave me capsules to eat. and as soon as When he ate that capsule, he started glowing. It started glowing. It started glowing. He said Ok. Now this is our first step. As As soon as the blood came inside, this is what you can see Yes, we call this Bowman's capsule. What Do you say anything? Bowman's capsule and the Bowman What is inside the capsule? Glomerulus And what does this glomerulus do? Glow Glow That is, it started shining. That's why I said glow Glomerulus. And what does the glomerulus do? Is? Does filtration. That is, the first one Filtration takes place here. It pulls in all these things. as much as blood There are dirty things too, he will pull them all away Inside. And he puts it inside himself here. Is. Ok? Now the blood says hey thank you Dude glomerulus dude. well i'll go Friend, my work is done. So now watch the blood go Seems like it is going it is going. Then the blood The blood came to be realised. I am a scam He went with me. So brother, I got scammed. So How did the scam happen? Friend that was the glomerulus no i said yes yes he knows what do it? I said tell me. he didn't mine all the good things I had, like my I took water and my proteins as well. It is wrong No? I said it is wrong. So I said now what will he do? So the blood said I will go back And I will get my things back from him. Look now Glomerulus is a good guy. Now when he When I go back, look here, this is what you are looking for Can you see what is happening here? Is? Reabsorption is taking place here. And We call this process selective. Reabsorption. That is, the one who is good for blood There are things that the blood needs back Takes the blood. Ok? now blood speaks Hey thank you friend. Well this is the whole The loop travels and the blood flows from here goes. Now what is the third step? Now all the that all the filth comes from here to this place It gets stored. Ok? and this is what we what do you say? Collecting duct. this which This part is the collecting duct. and similar We call this process tubular. Secretion. That means whatever this dirt is We finally put this dirt in the form of a tube Put it inside, that is, inside a tube. And this is what we call tubular Secretion. So look son, there are three parts. With the help of the story, you can remember the whole thing. Will be done. What is the first part? Glomerular Filtration. What happens? Blood Enters The Kidney and in the nephron nitrogenous based Glucose Water Amino Acids & Access Salts are filtered out this initial filtrate Enters the Bowman's capsule of each nephron. Ok? What happened in the story? came first You will not welcome feeding Boman capsules. Take Brother, take the capsule. began to glow, to shine Put. That means glomerular filtration has taken place. Remember the first step. son a trick Should I tell you? You should just remember this. Headings You will make the inside one. you so much There is so much talent inside you you can make it i know glomeral remember filtration next step selective reabsorption I told you when with him If he was cheated, what did he say? He backed down I asked for my things back okay I gave them an edge The filtrate moves i.e. when the blood moves forward seems to be useful through the nephron substances such as glucose amino acids Salt and significant amount of water are reabsorbed means it asks for it back It's okay, now the blood is gone, what's left now? Tubular secretion comes last That is, urea, additional water and excess salt are secreted into tubules, that is, as many There was also dirt like urea etc. excess water All the tubules that make up the collecting duct I I told you there is a collecting duct inside it It reaches there. Ok? which then opens Into collecting duct. the urine than the floss From collecting duct into ureter. i.e Now see where it will go from the collecting duct? Where did the blood go from the kidney? Ureter. Urinary bladder urethra yes then three destruction How will you remember the three brothers and three destructions? GST is being applied on everything these days Pe GST Global Filtration Selective Reabsorption and the final is tubular Secretion What's up guys let's ask some questions So this is the whole process, isn't it? I told you, you can see it here yes how was the urine formed son how is it The complete process of urine formation will be completed Told ok then urine transport Who does the ureter and who does the storage is it son? The urinary bladder does. And Where does the final excretion take place from? Excretion occurs say with the help of urethra From. When we feel that no, no, now So friend, oh brother, I will have to go. Isn't it? Yes. Then with the help of urethra we can expel urine. Let us throw it out. Let's ask some questions Tell. which part of the nephron is Responsible for filtration? which part Is? Which part of the nephron is that Does son do filtration? Capsule feeding Was. It was glowing in it. Glomerular Filtration means Bowman's capsule. Very Excellent. Next question. how is urine Produced in human body? Now whenever this This question comes up and is asked again and again How is urine formed? so not inside it I'll tell you the whole process of nephron. Is. I want to tell you that the blood is It came to the kidney. There was nephron in the kidney. Now Three steps occur in the nephron. GST, Glomerular Filtration, Selective Reabsorption and tubular secretion. So You can find the entire process here I have to tell you. Ok? explain the basics Process of urine formation. Then you complete Will you tell me the whole process? means the same three You have to explain the whole step. Correct Is? state the function each of the following The Human Excretory System. the first is kidney. What does the kidney do? Kidney one Filtration is working. of the kidney Nearby is the nephron. So the one which filters the blood He is doing the same thing with his kidney. Ureter What do you do? Transverse Transfer Urine From kidney to urinary bladder. Urinary What does the bladder do? Stirs. Stores Urine until we urinate They would have done this by storing the urine keeps it. It's not like that for the whole life Will store it. I don't even have to take it out yes bhaiya. Yes, its okay. Write One Specific function each of the following organs in relation Of Excretory in Human Beings. Ok? Renal artery. Tell me what does the renal artery do Is? I have brought the artery from the heart. Whose On the side? Towards the kidney. This is what is in the kidney Those who have impurities in their blood She brings it. i.e. renal artery caries the Toxic blood. The blood which contains toxic substances that bring it to the kidney Is. Urethra. You urinate. Glomerulus What is going on inside it? There should be filtration Used to be. tubular part of the nephron What are you doing? doing tubular secretion Used to be. Isn't it? As much as tubular secretion also our urine is formulated and it is collected goes into the duct from here and collecting Further from the duct into the ureter. what do you understand I? You can also see it. tubular part of The Nephron Reabsorbs Useful Substances like glucose, amino acids and water Secrets additional waste into filtrate. That means what is its main work, son? understand that This is the tubular part of the blood Dirt had arrived. more stuff in that mess He adds it. such as extra water, Glucose and all that. Ok? So one of this Is there any other work? That it adds this. Memory Is it also written here to keep it? That All the extra things are substances Like Glucose, Amino Acid Secrets Additional waste into filtrate. That means he All the dirt and waste that's inside it He puts it in. Ok? very nice. What Did we understand this whole story, son? Where can I find these notes? the kids are asking Are. You will get the notes friend. so much load in description on telegram Why are you taking it? Let us go. what is hemodialysis does it happen son? A small NCERT The column is hemodialysis. Hemodialysis means Artificial kidney. Ok? whose The kidneys get damaged, one of them is completely damaged It takes a process. You just understand the definition. Hemodialysis is a medical treatment used to filter and clean the blood of people with Kidney failure. those who suffer from kidney failure Is. to clean their blood Let's use the process. whose name is Hemo dialysis. dialysis means blood To clean. Ok? Ok? So the machine's With the help of this blood is extracted, clean and the blood is put back in Is. Come on, let's look at a question, son. Its. What will happen if the kidney stops Working? how is this condition treated in Hospital? If the kidney stops working Do you know what will happen? Blood is not clean will be. If the blood is not cleaned it will become toxic Substances will form and ultimately death will occur will go. Now how is this solved in the hospital It happens? One thing is dialysis. hemodialysis which I told you about and The second process is the kidney Transplant. These are two processes. There is one dialysis and one kidney Transplant. What is it with the help of? These It can be solved. Let's have one last The topic remains which is excretion in Plant. Then this chapter is ending. I know you're tired. I am not tired Am. How are you tired? I will kill you. Yes. get tired Not there. Let's excrete this plant. See Do plants also excrete? Yes I will do it brother. How to do it? Firstly he expels carbon dioxide. Takes out the oxygen. Isn't it? Obviously That's right. So first of all oxygen and carbon Dioxide is diffused through stomata. That too is a type of excretion For. That too is an excretion. Ok? Next Access Water Is Removed By Transpiration. that too is an excretion For them. The more water there is, the more this leaf I will leave it outside. Is it ok brother? I understood it Went? next. Plants can even lose some of Their old parts are like old leaves and Bark of the Tree. That means, what happens? it your leaves which have become old They also start dropping it. good one very good The concept is to be understood. Don't Plant Your Waste are stored inside the leaf. Leaves Store it inside. Do you know? that you see the leaves fall No, do you know why it is raining? Because Inside them was the plant's waste store. Yes. So plants store waste. Leaves inside the leaf then make them fall Are. Let's get it shed. Ok? Other West Produce Like Other Wet Products Like Rays in and gum especially in old xylem Sales which can also be lost by a plant understanding have you seen something There are plants that have a stem some gum type nickel of the plant It has been happening. Glue type thing was coming out Is. Have you seen the rubber coming out? Do you know what it is? Is? That is all waste from the plant. yes so Plants also remove their waste in this way Are. How? Forms of Like Resins and Gum In. and the last plant is also secret some West in the Soil. That means even inside the soil What do they do with their waste particles Are? Let's release it. then the plant will never If asked how the plant excretes Is? Does the plant excrete? Yes, He does. gas exchange expels water Extracting leaves using gums and resins stores it in and drops that leaf Is. and with the help of the routes What does it do to the soil also? Excrete Does. Ok? very nice. so this It was a whole process. you can see this yes. You must have seen a big tree like this Is. Something like gum comes out of it. what is it then? That is waste brother. They It is west. But it is useful to us. They It is a different matter. Let's name one gaseous and one Non Gaseous Waste Product Excreted Buy a plant. A gaseous plant Write the product CO2 or oxygen, whatever you want. Is No? because oxygen is used in photosynthesis He releases it. and non gaseous non Gasius, say anything. Gums are resins, right? We can write anything. Ok? Resin, Latex, Gum, Excess Water, Organic Acid All of these, any of these. Finally friends Our chapter ends here. But the most important part of this chapter what was it? Understand this. That which I have given you in heart I explained that we should not forget it. don't forget that Is. Isn't it? once again the emphasis is on the mind Put it in and tell me what it was? P V Sindhu said Ayo. what did you say? Ayo. what to do Was? He had to make a video call. Isn't it? Who was it to be done with? From your family members. What Did he tell you? Yes. yes i told the PA remember that it was pulmonary vein iota venacava and lastly the pulmonary artery that There is a lot of flow as many questions as there are I could have done everything, I guarantee I can say this is one of the best one shots outside this not in your paper It means that PK Bhaiya will not come It's the tongue. Isn't it true that words have value? Correct Is? And if ever you feel demotivated like this If you feel like this then remember one thing friend Ki Na was a great basketball player. I saw one of his interviews and You know, he said a line The day before the basketball match I know what do i do i imagine myself I imagine myself scoring a goal doing a basket while doing a basket I imagine I'm doing baskets Just why does power lie here in your mind I am your powers if you feel like it that your marks in exam If they are not good they will not come but if You seem like you are very If you come with a great score then you will will you come The power is here. The power is here. Remember this. And with this we end this lecture Are. Always smile, hide your sorrow. Wool Time will tell people who we are.
