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, bring more. A dangerous, powerful 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 Could have come. Nephron is not 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 Questions are those questions which are in your paper. You can repeat everything inside The only one available within the One Shot. Correct Is? So get ready because Ishant Bhaiya is coming. Have gone. And why to fear when PK Bhaiya Is here. So remember, there's nothing to be afraid of. Is. How is the passion 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. Don't 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 It's a lovely subject. Why? do you say it People say that biology is a very lovely subject. Why? Because look, math people calculate x The chemistry people have gone out to find setting up your chemistry and Find poor Newton Baba from Physics. And we are biologists, we are experts in life. Knowing about. And so this chapter Its name is life processes. Life What does processus mean? Process That means work. Life means life. That means all of them processes that lead to a life It is mandatory. That means it is important. i.e What are life processes? All Those Functions that are 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's for me Life process. Now you will call brother. Running is also a life process. without him We cannot survive. Look, what do you know, friend? That should be a live process for you. Because Now you have become addicted. But that phone get out of addiction because we I am studying. Ok? Operate the phone on There is no live process. Sometimes ask in the paper Take it and you 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's what this entire 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 this? We are going to read them one by one in detail. Come Go. Let's start first From nutrition. Ok? Now Nutrition What is? what to eat brother Is it nutrition? I said no wrong catch You have taken it brother. Food is not nutrition Is. Eating Food and Obtaining Energy That means taking energy from within it also. 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, and besides that, protein. You eat, you eat vitamins and minerals. Mainly so You only eat fat. Burgers, Pizzas, Subs 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 occurs and Utilize. This is a very important line. Son. Utilize means to use that food, To get the utilization done. Isn't it? What is that too? 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 It's a thing. 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'm hungry too, you Also hungry. Both will study. Now look There are two types of nutrition. Autotraffic and one heterotrophic. Auto means that one Not auto, not 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 brother, our mother again Does it do autotrophic nutrition? Because our mother does not cook her own food. Makes it. I said one will do. No, bro. I call you foolish child with love. Boy. Ok? I don't want to feel bad. You You are my foolish child. Correct? so stupid boy It's not like that. What is autotrophic nutrition? There is a type of nutrition in which yes The organism makes its own food. But from inorganic substances such as Oxygen, carbon dioxide, water. Oho The food cooked in your house is a vegetable. 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 Simply Inorganic Substances like CO2, water in the presence of sunlight and chlorophyll. Ok? Now look 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 Plants do. Even in small 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. Ok? Gin Plants It contains chlorophyll. About this We will talk in detail. Just understand this much now that photosynthesis is a type of autotrophic Nutrition. Apart from this, good plants Who else does it? Autotraffic These photosynthesis in nutrition. then some There are algae. Some are algae. Some? Contains cyanobacteria. All of that too perform photosynthesis. Apart from that, one Chemosynthesis occurs. Chemosynthesis is a It is a process in which an organism rebuilds itself. It makes its own food but requires few chemicals. with help. Is it okay son? So remember to type off Autotrophic nutrition in which organisms Prepares their own food by utilizing Chemical energy. Now its example is very It is necessary. It 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? Okay, that's great. Did you understand? Good. Now What was this heterotrophic brother? Heterotrophic as in you, all of us. We You know, 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 heterotrophic nutrition is. 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. See how important plants are. Yes brother. We think trees are important. 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 If there are no such things, how will the world function? Now look I will first tell you the type of Heterotrophic nutrition. heterotrophic There are three types of nutrition. There is one Holozoic. Now look, don't be afraid on hearing the name It doesn't happen. I know biology in 10th. You have come here just after seeing biology. Brother what is this Did you read it? Holozoic. Hey stop. One Holozoic, one saprophytic, one parasitic Understand. What is Holozoic Nutrition? Holozoic. What do you understand by Soik Holozoic? Some? It is a big thing. That means we are also elders. So Holozoic nutrition is what we follow We do. What do we do? We are a big picks up food and puts it in the mouth Put it in and eat it. this is what you do No? like this and when you want to eat a burger then like this Let's do it, right? Isn't it? same with you What happens? When you are at school The friend brings Maggi inside the tiffin box. So that tiffin box before recess It opens and everything starts to creak. He eats quickly. Isn't it? whose The faster the speed of eating, the Will eat more. Isn't it? Yes. So, holozoic What is? Animals 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? Okay, let's read Parasitic now. What happens? What is parasitic nutrition? Is? Parasite. Parasite, you understand? Is? You must have seen that Annie, Parasite. Is No? So look friend, this parasitic What is nutrition? be careful Understand. Parasite means something that Be on someone else's side and get your food from him Pull. Like for example in childhood You used to say that there were lice in your hair. hair What happened to me? There were lice in my hair. Did you say it or not? Tell me quickly. You used to say that there were lice in your hair. Joo Jo What did you do to your hair? Your It 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's up to us. Ok? above us And what are we to him? We are his Host for. host, that is, from whom he Obtains nutrition. Ok? And derive nutrition from it. remember In parasitic nutrition, the parasite It happens that he does not kill the person in front of him. Is. I just kept getting my food from him. Is. Remember the example. Substantial Example Is. Cuscuta cuscuta. cuscuta What is Cuscata? It is a type of plant And I'm telling you to remember this because This is the only plant that Parasitic nutrition follows. This is the only plant that is cut like this, isn't it? His What else are there? Contains ticks, leeches There are. You know leeches, they 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 most useless saprophytic. What does this do to the saprophytic middle? it Na eats dead and decaying organisms. But there is one thing in it that it is not to be eaten. It digests it outside itself. to eat It digests it outside itself. some chemicals It expels food so that it digests outside. It happens. and then directly Absorbs nutrients. i.e What's inside it? Organisms Feed On Dead end [ __ ] matter. Remember this is outside digests and then absorbs He does it. Its example is fungus. And What is the biggest example? mushroom. Write it down brother. One of the biggest examples is What? mushroom. The mushroom you eat is a Types of saprophytic nutrition only follow Does. He would have been 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 have been asked from here. I came brother This is an important question. See 2017, 2020, 2021 Dekh Bhai Which of the Following Is the organism saprophytic? saprophytic see holozoic parasitic between ka bol yes saprophytic then who is the middle one Of these, the mushroom was just mentioned Who among you eats mushrooms? Do you eat mushrooms? Mushrooms do He eats saprophytic dead and decay. Remember this thing which of the following Organisms Show Parasitic Mode Parasitic Which of these looks like a parasite? cuscuta I will remember Kaskata, my son will remember the next one. What is a very big question like this? These days, the elders are coming. long paragraphs They give it to you and ask small questions. Are. As an Organism Was Discovered That lacks chlorophyll. chlorophyll in it 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 hit the person in front of him. Just Absorb Does. Hey, you already know this. These So you already know. last one Parasite Parasite. very nice. That is, it Is parasitic. What is Parasitic? Its 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 Obtaining. Just look at it. He does not kill As for the person in front. It Show Specialty By Infecting only particular plant Species. Ok? I've got it? very nice. Come on brother. Now let's move on to the next one. Autotraffic In nutrition, I told you that photosynthesis, which I I will talk in detail. And children like this Bhaiya, it seems that photosynthesis in 10th is so Who will ask EG? and whoever asks There is a reaction, they also ask. 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's the plant, friends. Your We present the plant for you. Are? Now no one He will not say that it is a fake plant. So look brother In this we saw flowers growing in the plant. Have given. But this green part is What is the green part, friends? So this is green The 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 thing 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 and Fourth is water H2O, very important. Correct Is? So first of all see the reaction and this The reaction must be remembered. forget this It is not even by mistake. What is 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 food? Glucose. Glucose itself is food. Glucose Remember the formula. C6H12O6. So glucose is formed simultaneously Oxygen gas is evolved and H2O gas is given out H2O is not gas, H2O is water coming out. Okay, did we understand? great okay so these raw materials What is the four CO2 molecules for photosynthesis? with speak CO2 H2O and what is sunlight and Chlorophyll is great friends, let's go, right? So remember what chloroplast is the Sites of photosynthesis which are green Pigmented means there is something inside it which is called The one I am talking about is not the green colour. What is that? Chlorophyll. That is, if so It is because of chlorophyll. Ok? very nice. 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 close to 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. Trapped in your net He took it. Trapped all the energy. Now what did he do? that light energy Get it broken down. Conversion in the second step of light energy into chemical energy. For him Converted into chemical energy. See Something is going wrong with the light. Now that What did he do with the help of chemical energy? The molecules of that water broken down into hydrogen and oxygen. The hydrogen inside broke into oxygen. Two The work is done. Now the third step and the most Important step. Now this CO2 was CO2 carbon dioxide gas is converted to Who does it go into? Carbohydrates. Carbohydrates i.e. glucose energy. So What is inside this energy? Convert It is done. So there are three steps. First Called him to me 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. Oh, simple. This seems difficult. These You are really finding it difficult. Who I am saying it and it seems so difficult. O dear This much is easy. what are you talking about friend Friends? Ok. Okay, remember one more thing. 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 animals store In whose form do you 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 it stores in the form of starch. Are. MCQs have been asked. remember Take. I will go ahead and answer all the questions. Let's talk about these gases now, brother. How is the exchange going? This CO2 comes in Used to be. Oxygen is running out. How are you Used to be? This is done by stomata. Stomata What is? There is a type of knuckle. Por means hole. Now these holes as I give you for Let me explain the example. accept accept look There are no 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 guard cells do? As soon as water enters the guard cell The guard cells open. Open as soon as the water comes So the stomata opened and the water went in. The guard cell closed. open water came It went and stopped. Ok? So the stomata Who controls? This is its diagram Son. Diagrams have been asked repeatedly. Remember the diagram. This is what you can see Ho Bean like these are guard cells. as soon as If water comes in these, son, then it is stomatal pore. Let's open it. And as the water ran When it goes in, it closes the stomatal pore. We give. Ok? Okay, remember this diagram. Keep. Inside this, this green thing that gives you It looks like this is nothing. This is the same Chloroplast. chloroplasts very nice. Ok? Let us understand this Went? Everything runs on water. Good What are the functions of stomata? first of all You know, one is the exchange of gases. There is another function. Do you know what happens? Never overload the tree too much 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 comes out of the leaf goes. And we call that process Transpiration. Perhaps you have attended smaller 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 involves? Who Access of water is done with the help of leaves drops out. Have you ever seen this If yes, the leaves of the tree are slightly wet You see it due to transpiration. So stomata have two functions. One Transpiration and the release of gases To exchange. Ok? Understand what the matter is Did I come? very nice. something good Let me tell you my observation. For whom? For Desert Plant. Now look at the desert The plant is completely different. This was normal Plant. Now with desert plants, not one It is a big dilemma. There is a crisis. what that Man, if it's so sunny during the day. If brother It will open its 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 does he do, son? be careful Look Stomata opens at night. 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, it keeps the CO2 inside. Is. And what does he do during the day after that? Keeps the stomata closed. Photosynthesis on He does it. Because the light is on during the day It comes. So photosynthesis happens during the day only. will be. It cannot 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 Trapped CO2 at night. is smart Desert plant. Smart son, smart. Turns out he's smarter than you. I felt That you were the smartest, son. But what did this turn out to be even worse 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 Pore presents mostly on the Underside of the leaf. underside of leaf What happens? There are tiny pores which What do we say son? stomata speak Are. very nice. Next question: Where are you? They are 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 their opening and Closing is regulated. who controls Is? Guard cell. The water came open. 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 do it. But I Every activity for you, everything I have come son. Everything in detail Let's read. Ok? And that too in less time Let's read inside. This is the thing PK Bhaiya of. Ok? Yes, I flexed it. Let's see what happens inside it? One The activity is within NCERT. not in this KOH is a salt, meaning potassium. Hydroxide. He is kept. Now remember Keep what does this salt do? This converts CO2 It absorbs it. i.e. carbon dioxide and absorbs carbon Eliminates dioxide from nature. This means that carbon dioxide is finished in this place. It's done. what happens now? This pot is placed in this jar Is kept inside. This tree was kept Is. Sunlight is coming in, but isn't it? Unable to perform photosynthesis. Why not Can you do it? Because look how it is kept. This What did you do? CO2 pulled. and you know If photosynthesis is to be done then four raw Material is important. If any of those four If any brother goes missing then there will be trouble. It will go, there will be a dilemma. And one brother is missing. Done. Which brother disappeared? CO2 disappears Done. Now that CO2 has disappeared, this What won't be able to happen inside the case? Photosynthesis will not be possible. This activity Remember to. Sometimes questions come up What does KOH do? So KOH is absorbed It absorbs CO2. Let's go sir. very nice. Now let's 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 than us It was a creature. Who? Amoeba. other than amoeba And there is another creature which is Paramecium. So now We will talk about amoeba. a little 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, it is very Good things are happening. two friends It is a lot of fun. would have been hilarious Is. But when there are three friends, there is one person That I would have been continuously insulted. Is. One is laughing out loud. 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, neither rich nor poor Neither rich nor poor, I had two friends both of their pigs Well, that's what we used to say to each other. It's a matter of time, I mean I'm better 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 part of a holozoic nutrition. There are steps. What is the first one? Ingestion. Ingestion 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 are their names? Pseudopodia. Ok? It has hands Which we call pseudopodia. his help What does it do with? takes food in Is. Suppose you want to eat. I ate like this Took it inside. So what did I do? Ingestion Get it done. The next process is digestion. What is digestion? Enzymes are secreted in food vacuoles breaking down the food Inno Simple. That means breaking down that food Get it done. Get it digested. the next process would be This is absorption. Now look at digest food. I have digested it. Now that food There is an amoeba inside it, so it should be absorbed as well. Will have to. So that's what we call it Absorption. Digested food is absorbed into the 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 Energy has been taken. Now that energy Utilizing means moving around, a little Moving here and there. What is happening to him? Energy is being used. So the same process We speak of assimilation. i.e. absorbed Nutrients are utilized in various ways Life processes. and the next one comes Ization. The last evacuation. Ization. ization, that is Throwing out undigested food. Memory There will be ingestion, digestion, absorption, Take out assimilation and egestion. Now this Son, the diagram has also been asked repeatedly. These Remember the diagram. First an amoeba Is. Where did this cookie-like amoeba come from? Are you gone brother? So, are you enjoying the cookies or not? Isn't it a tasty cookie? So food Part this amoeba what is this? Pseudopodia. It takes it in with the help of pseudopodia. Ok? So what did he do now? It has inside Took it. After taking it in, it destroys its food. inserts it into the vacuole and Digestion starts. So here you are You can see that digestion has started. Now As soon as digestion starts, here What happened? Absorption and assimilation Happened. Isn't it? absorption energy Absorb and all the life processes I have worked inside it. and the last step What happens? The last step is outside Removal Whatever is waste, whatever is waste What does it do? is thrown out. We call that ization. So these five Remember the steps. If you remember these five steps If you do, there won't be much problem. Ok? Now he has another brother whose name is Perimysium. See Paramecium and Amoeba All the processes of both are same. just one It is different. First step is ingestion. what is amoeba used to do? eats food with the help of pseudopodia Was. What does he do, son? It does not have There are hair like structures. whom we Says Celia. Celia. This diagram also It is important. It is not that important. Butt is fine. This gives you hair like Projections are visible. We call them Siliya Let's say. Son, this is Paramecium. These There are cilia. So what does it do? of cilia Do not take food to your mouth without help He comes and puts it inside his mouth. Is No? near the mouth, just inside the mouth of LA He puts it in. So, 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. is the brother of Amoeba. That's why I said he is my brother in the beginning. Ok Brother, very nice. ok now a question It was asked repeatedly. differentiate between Amoeba and Paramecium based on mode of Nutrition. What is the mode of nutrition in these Of both? It's the same, son. Holozoic Nutrition. Holozoic Nutrition. Beans. Next is locomotion. locomotion How to do it? So the amoeba moves With the help of pseudopodia. And with whose help is this? Does it? Paramecium cilia. Hair Like Structure. Very nice son. Let's go very Correct. Now it's finally here friends humans 's turn. Now look, humans are also Hollows Doing nutrition. So 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. been asked many times Yes brother. with a very sad atmosphere I have to explain this diagram. asked this Has gone. So remember this. Look at the start It is about eating food. Now brother, give me food If I have to eat, how will I eat? oh from the mouth I will eat. from my mouth, I will 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 begin? People think that food gets digested in the stomach It is not happening, it is not starting in the mouth Is. Yes, it starts in the mouth. Let's take a look at what happens. You tell me one 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. Burgers, pizzas, etc. Do you want to eat? Momos, noodles, yay yay. No Son, whatever you want, you will get it. This has happened till now and will happen today. So today we will eat Son, bottle gourd vegetable. have loud applause Ready to eat gourd vegetable Lets do it. So now the gourd vegetable has arrived. And you and I have eaten. Ok? Correct Is. No no, it is good. gourd Vegetables are good. Healthy Healthy Healthy. Ok? So now we have eaten gourd. Vegetable. So see what happens first, son. Is? First comes ours. In the mouth. Ok? In the mouth and in the mouth What happens? What is the work of the mouth? Is? First there is the crush. Food. this that Wally is not a crush. Food is crushed. Food It starts breaking. Ok? So what happens? First up will be Food Crush. After that Salivary gland is in our mouth Inside it releases saliva. Saliva You know it. Ok? So saliva It is released. Now the main work begins. Look, our tongue 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. starch What does it do? These maltose Maltose. Remember this is a simple sugar. So what does this complex sugar do? This is a simple sugar called maltose. Converts it inside it. who is doing it Is? Salivary amylase. Salivary amylase. very nice. Now the food goes down. Esophagus means food pipe. food pipe to eat How does one push down? There would be a movement Is. This doesn't happen like this doesn't happen like this. Contraction is a movement that Little by little. Isn't it? So we call that movement It is called peristatic 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. Wait Go. Ok? So what is in the esophagus? Is? There is a movement going on, contraction Of expansion. We call him Peristylic movement. Remember this. Ok Brother? Where did the story reach, son? Story From here, ding ding ding, now here But it came. Now the stomach has arrived brother. Now look First of all, how does the stomach look in shape? You? J shaped is J shaped. Ok? Now as soon as the food goes into the stomach, the stomach Three brothers were sitting, 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 elder brother's name was HCL hydrochloric acid. So 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? HCL. By the way Look, the stomach releases gastric juice. Is. Gastric juice. and the same gastric juice 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 There are also germs, bacteria you burgers, Eating pizza kills them all. All those which the golgappa seller brother made dirty I touched it, it hurt. Tata bye-bye. Good Bye. Isn't it? It has another function. about him Let's talk further. Ok? The first Given acidic medium. Next comes. Second Brother, mucus comes. These seconds brother. mucus What does brother do, he protects From the 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 that big brother He helps his younger brother, right? Because pepsin can only work in acidic Environment. And who will provide the acidic environment? Used to be? HCL is giving. Because of this I It was said that another work of HCL is help. Pepsin action. i.e. to make pepsin work Who is helping me too? HCL is doing it. Ok? Okay, now tell me one thing. Have you ever had acidity? Acidity Why does it happen? Acidity is sometimes caused by When is this balance of HCL and mucus? The level of HCL in it increases and when HCL levels increase and mucus is reduced Mucus is thin, what is mucus? There is a lining on the wall of your stomach. You start feeling a burning sensation in your stomach like this It seems like, oh brother, how can this jealousy happen? It is inside the stomach and this is why Son, when the levels get spoiled, the levels Everyone will come out, okay, the levels change. HCL and mucus, okay, now let's get down to it. Now the food was going downstairs now forward to eat Had to go near the small intestine Gives a name to the small intestine I am a small don. Why? Because its It is small only in name. Otherwise, it's small No. Isn't it? It is small only in name. But This is Don, son, Chhota 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 Not small. Ok? Now it was going By the way. The food was going. go to eat It was in the small intestine. Then there are two Entry of goons. Bring the goons Friends. So now tiding tiding has arrived Tiding two goons. The first goon comes and The goon says, yes sir, where are you going to eat? Where are you going, then the food said that brother, he is going there, that small Near the intestine, both the goons He said, let us also help a little, who are the two goons? If you look carefully, son, a thug Who is this, one is a goon, this is a lever and the other is small You see the pancreas, what is this? pancreas and what is this liver okay now What happened was that I was going to eat and two goons came. The liver comes first, so the liver speaks. Let me help you a little first, then for the liver What was nearby? There is no bladder near the liver. There is a storage which we It is called gall bladder. inside the gall bladder He stores a juice. 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 of the bile juices 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? Secondly, another function of this Emulsification of fat occurs. What is emulsification of fat? What is emulsification of fat? of fat Nor are there large globules. For them Break it down into small parts. Correct Is? breaking into small droplets or Then we can say that the globules are are large globules, What does that do to them? of small globules Breaks it inside. Ok? Emulsification It does it, it breaks down. Two Got the work done. The first thug was happy that I also helped myself to some curry. know now What happened? The ego of the other goons 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 about ego She 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 one was a goon, son. Pancreas which I have just shown you in the image It was also shown. 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 give it to her, so he did it Three will do. He is also a goon, not much work. Will do. Ok? So it produced pancreatic juice I 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 it brother Pepsin also cleaves proteins. Yes Pepsin does it, so does trypsin. Is. Next lipase you're eating fat right Who will digest it? Lipase will do it. And next comes pancreatic amylase. Well, where did we hear this word amylase? We had heard about amylase, brother, salivary Amylase. Pancreatic amylase here. So the function of amylase is the same here as well. What will he do? starch that is starch digestion of carbohydrates Will help in digestion. Ok? What happens in the digestion of carbohydrates Will he? Must be helping. First goon two Work. What did you do? Bile juice was extracted. 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. Breakdown. Ok? what is here now Happened? Here both the goons became happy and The food then 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. Final digestion takes place here. Correct Is? And what is formed by final digestion? Is? You remember that. The protein you If you eat it, it will get 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 you ate that in your fatty acids and along with 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's done. Now this is about the little don What's the work? Of the small intestine. Yes Digestion happened here, but it did just that. Not there. This is Chota Don. Another function of this Is. What does he do now, son? neither this nor this There is another function which is absorption of Food. Digestion is done. What was the next step? Absorption. so it has some finger like There are projections, son, which we don't care about. Do you speak? Which we call Vilay. That is, consider that this is the small intestine and from it the finger like There are projections. 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 villa? 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 its What is the work? This is the absorbed food No, now this means digested food. Absorb it and send it into the blood. Its This is work. So there's not a lot inside it There are blood vessels. Such blood vessels Are there. So what does it do? to eat He pulls it out and throws it into the blood. Correct Is? So what is its main function? Its main What is the work? The main function 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 projection, isn't it? It's finger-like. Why is it? A question must have come to your mind. Because this is a finger-like projection No, this would increase the surface area. And more food can be absorbed. Ok? Next Thing: Rich Blood Supply Helps Transport Absorb Nutrients Into All Body cells. Because there are a lot of There are blood vessels. So he gets to eat It absorbs it. Ok? Nutrients are used for energy growth End repair. You already know that. Correct Is? So, there should be 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 There is food, it will go here. and undigested What will he do with the food? It will draw the water. Who There is water, it will pull it. And then this waste You can see this completely in the west. through the anus anus down to your west 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 performs ejaculation That is, removal of undigested food. Correct Is? Who controls this? a muscle It is the anal sphincter muscle. He controls it Does. very nice. I understood this thing. Now One question is asked repeatedly in the paper. The herbivores that are inside, like Cows, buffaloes, 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 it. Correct Is? Now the digestion of cellulose takes time. Is. Their digestion cannot happen quickly. So Because Digestion Takes Place That Is Why Their small intestine is larger. Ok? I have written the answer to this here for you. Is. Ok? very nice. Let's do this You have your entire story, now nothing. questions that will help you and Things will become clear quickly, its answer Tell me, this is very simple, what's wrong with it? I am having trouble, brother, see what it is. and 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 nice, it's important brother. Yes, it starts from the mouth itself. Your mouth waters, doesn't it, Mummy? She cooks tasty food. Yes. Good Have you ever noticed that when you come home If you are from anywhere outside, then first of all we What do you do? First of all, 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 was somewhere around, I would have found my mother. Is. Mom says yes, say nothing. All we need is mommy. Isn't it? Us I just want to see where mom is. What to do Is it happening? Bus. We have nothing to do, Mom. From. So we need mommy. Have you seen it? I mean, I do this a lot. Even today I do. Ok? So let's look at the next question. Are. In human alimentary canal the Specific enzyme juice secreted in the Location. Look, three locations have been given. In the diagram. The first is location number one. These It's Mouth. What happens in the mouth? Saliva Amylase. This is the second location. what was this Son? Liver. What did the liver 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 one will come from bile juice and Third, trypsin. very nice. So the answer is B. Such questions also come. next Let's see the question. In Human Beings When the process of digestion is completed The Protein, Carbohydrate and Fat are Break down into what? Proteins break down into amino acids. carbohydrates break down into glucose Are. And what do fats break down into? 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 hydrochloric acid do? Two tasks. Kills germs. Acidic Provides an environment for pepsin to work Found. What does pepsin do? to protein Breaks it. What did bile juice do? Two Work. Bile juice is secreted by the liver. Two Reduced emulsification of fat and food Alkaline Basic-Basic. Yes very nice. Remember the story. The story of two goons. These It is very important. This is repeatedly mentioned 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 they happen? their work What is? Absorbing, Digesting Food to be taken into the blood. How Do They Help In Absorption in food? So you have to tell How do you help? So one, this surface Let's increase the area. Because These have finger like projections and What do others do? There are a lot of them inside There are blood vessels. So to eat this Directly into the blood, meaning digested Food is put into the blood. Let go very nice. One last question. complete The following chart. All you need is this chart Have to complete it. This is your homework. These You will tell me yourself in the comments. We are talking about the gastric gland. The gastric gland does three things. A What does BC do? gastric gland What is? Stomach. What is stomach? three brothers All three, 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, by the way. 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 the oxygen we breathe Producing energy with help. i.e We are breathing but respiration Our cells are doing it. each cell Does respiration. do you remember me You will remember only one line, ninth class of. Mitochondria is the powerhouse of the Cell. Isn't it? Anyone can ask this, brother. Mitochondria is the powerhouse of the cell. Is No? He He He comes comes. I also have a habit Inside the school, people didn't think so. that I would sit on the back bench It was true that my teachers did not think so. If this is not good to read then I will back out. I used to sit on a bench with my friends I used to have fun, but I liked science. etc. I used to get good marks so one What happened next was the teacher saw me and called me. That you are standing at the board and have come to solve it now. The teacher thought I might not know it. Stood square and caught Sara's entire answer It was written on the board and I turned around and Sir said okay. Good at studies but more fun If you do it then brother, also about back ventures and Look, back ventures have also come and it is fine. Yes, so look at breathing and respiration. What is the difference between this and that? First of all, the difference Understand what Variant Breathing is. Breathing is a physical process An inhalation is the release of breath Inhalation acceleration means breathing out Elimination and respiration are 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 created. And what makes energy? of ATP In the form. Remember the powerhouse of the cell? Mitochondria. Yes. Ok? Breathing What happens in? Breathing in only and Only your lungs work. Lungs and Whereas in respiration every single cell works. Is. No energy is released in breathing. Whereas energy is released in respiration The Form of ATP. It is also written here Is. Ok? Okay, this is 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 There are a lot of problems. what is respiration Is? The process by which organisms break down glucose into their cells to Release energy in the form of ATP. Which It is used for various processes. That is, one A process that involves what happens inside the cell It happens because we have digested the food. With the help of that digested food, oxygen is required. Energy is created with the help of in the form of ATP and utilize that energy goes through all our life processes What I am able to say inside today is this ATP I am able to say it because of it, okay, a lot Okay, now we are talking. of respiration first then of respiration You have understood the definition, but now The question arises as to how much this respiration takes Brother, if you look at the type of respiration No, it is of two types. I understand you this I will explain the entire process. But understand now There are two types of respiration. One is aerobic and an aerobic one. Aerobic means when our If there is oxygen nearby then the presence of oxygen The respiration that is taking place in Aerobic. Aerobic. Ok? So aerobic means It is coming, which means there will be oxygen here. And An aerobic means there is either less oxygen 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 have been asked There are ent questions 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 What are we doing in respiration? Breaking down glucose into energy. So the glucose present in aerobic is completely It breaks in some way, brother. Isn't it? As He had broken 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 at What is partial glucose? It breaks. It does not break completely. Ok? I will give you examples with the help of a table. I give. Come on. An NCERT table 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 does glucose break down? Now look, glucose first enters your cells. There used to be a cytoplasm. of the cytoplasm It is converted into pyruvate inside. 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 into into pyruvate. Now pyruvate has three Ways. He is saying, brother, which way? Should I go? This is one way, at least Which contains a lot of oxygen. So first if pyruvate is released in the presence of oxygen So this respiration is yours Occurs in the mitochondria of the cell. You know it. in mitochondria happens and energy is released. Energy Along with this, two more things are released. Remember this. One is carbon dioxide And one is water. These two things are also released It is happening. Is this clear? CO2 And the water is very good. Besides that, now 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 you get energy. Less Energy is created but a product is formed What is his name? Ethanol. Ethanol is the same Shri Shri Honey Paji ji had gone saying four Bottle wood work is my daily routine. Ethanol means That's it, yes that's what ethanol is. Ok? Correct Is? Alcohol is ethanol. Ok? So one is ethanol and one is carbon dioxide and energy at the same time It is made. Apart from that, if you assume lack of There is oxygen, that means there is limited oxygen. Well, first of all, this is absence of Oxygen is not an organism yeast. Yeast is an organism. His This process is happening inside. Correct Is? And if there is less oxygen. like it ever Sometimes we are playing football and our If there is less oxygen in the muscles then do you know what will be? Energy will be produced but a compound will be formed. Whose name is lactic acid. that which 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? What is happening because of this? Yes. lactic acid is building up and you The cramps are coming and going. very nice Son. Now look I've got you covered in an aerobic Explain two types of respiration. Aerobic then You must have understood. n aerobic two Please tell me the type. one that contains absolutely no oxygen Not there. One that has limited oxygen. Now these also have some names in which there is absolutely no oxygen because it Alcohol is being produced. So his name is Alcohol fermentation. Alcohol fermentation. Ok? Its name is alcohol. Fermentation. Where does it happen? In yeast It is yeast. Isn't it? Yeast does this. Ok? And what do our muscles do? Lactic fermentation. Because our muscles Produces lactic acid. Energy is created Just lactic acid along the way. and this The question has been asked repeatedly that intense I got cramps during my workout. They Why have the cramps come? Why have you come? Because our body has developed an aerobic Respiration has been done. Lactic acid is formed. Due to which I am feeling cramps There are. This has been asked repeatedly. Correct Is? Now I will give you an example of this. Am. Name the substance that is built up in the Muscles during vigorous physical exercise? Look, he has come. What is made? Lactic Acid Energy is being generated along with it. Very Correct. next question. which gas is released During an aerobic respiration in yeast. Which gas is released son? Anaerobic Tell me about respiration. Which gas? Remember me Brother, that carbon dioxide was formed, 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. Oh, that's the question, what 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 an intense workout happen? 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 carbon dioxide increases because we are breathing more and a Lactic acid is formed which causes I start feeling 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 arises. Look at this, I will tell you first and second. Is. What will be this first son? Tell. Glucose is converted into what in the cytoplasm? Tell me son, pyruvate is very good and pyruvate in the presence of What does oxygen give? It gives energy. H2O It gives and what else did it give? Yes, it used to give CO2. Brother, you are giving the correct answer. Let us now talk further about whose human How do we breathe now? Son, they see the breath I take I am taking it, how can I take it? Without this, son, there are some steps. And This diagram is not asked for that much. Butt again You should also see it once, I will tell you. The first It is the 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. Now what comes first? To all First comes the beta ferings. comes first Ferrins. Then comes the larynx. Children Confused whether the larynx comes first? Is. First comes the ferings. I am a trick I am giving it. PL Trick means profit loss. Profit loss. Remember it like this. So drink first Wala aayega means Ferrings will come again Larynx. Now this fering that happens This is what we call voice box. This which I am able to say no, there is a ding in my house. Ding ding ding ding ding ding ding yeah yeah What is? Voice box. Ok? voice box After that, this is what you can see. is trachea. What happens son? Trachea. Now there would be some rings on the trachea. are what I call rings of Cartilage. Now this ring of cartilage is known as What do you do? It Prevents Trachea From collapsing. If these rings are not there 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? Divide into two things goes. Which we call bronchi. These We call this what is going into the two lungs They say bronchi. Ok? Now the bronchi Such divisions continue to occur as we move forward. 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 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? Nostril breathed. nasal passage from where Going inside. Then came the pharynx. First Ferrings. Second larynx. what are the larynx It happens? Voice box. Then comes Trachea. What is in the trachea? Ring of Cartilage. What does Joe do? Keeps the Airway open. This means that we breathe because of this. Can take it. Ok? what comes after that Is? Bronchi in left and right. One enters the front of the bronchi Bronchioles. and at the end of the bronchioles A whole bunch comes. and if If I talk about a grape, that is, I am talking about I am having an alveoli. Ok? Now this What is alveoli brother? This comes most Importent. Now this is coming to the most Importent. What is this? Do you know? When you're breathing in oxygen and you're breathing out CO2 You are leaving out. you know how Are you able to leave? 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 brother? Is? Didn't understand. Look at what the alveoli are Does it? Alveoli: A Big Easy C Trick He uses it. Alveoli first I will tell you Let me tell you. It Is a Tiny Balloon Like Structure. Like let's say this is 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 one such blood vessel. Blood Who What is it? The blood that has carbon dioxide. So what does it do? That Oye my carbon speaks through blood Give me dioxide and this thing of mine You keep the oxygen in your blood. i.e Direct oxygen access to our blood and we exhale carbon dioxide Let's leave it. Who is doing this? The alveoli are doing it. Now in your mind The question might 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 possible? What kind of magic is this? 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 hemoglobin and oxygen. See What is hemoglobin? a respiratory There is pigment. Remember what hemoglobin is It happens? Iron-containing protein There is a pigment which we call respiratory pigment. Also speak. Ok? This is our blood RBC means red blood cell. About this Will read further also. There is a present in it. Now its name is love. It's love. It loves oxygen. So remember What is? Who is his main love? Its main Love is oxygen. It is larger than oxygen It's love. So what happened now is that look at your There was alveolae. A blood vessel is going from here Was. Now there is oxygen here. to this blood oxygen showed oxygen it said Hemoglobin. Hemoglobin in me Need oxygen. Take my CO2. Love This is a story. So it gave back CO2. in the alveoli and retain oxygen Took. That is, this exchange of gases can take place This is happening with hemoglobin Because of. This is why we call hemoglobin It is called respiratory pigment. remember Respiratory pigment. very nice. Correct Is? So this is the complete process son. Read out your oxygen from this Alveolar air diffuses into blood capillaries. Ok? carbon dioxide from the blood Diffuse into alveoli CO2 has entered inside. what happens now? When We exhale, then we exhale CO2 is released. This is the whole of There is a process. These are alveoli. Look at this blood. What did Blood have? Gave CO2 here. Inhaled oxygen. because of whom Took? Because of hemoglobin. Let's mean Who owns the whole game here? Hemoglobin Is of. So what about Alvolai? Do you have properties? Did we understand? two properties Are. Firstly, it is very thin. It is thin and contains blood vessels With the help of which it is able to exchange. Very true son. Now look at our lungs Apart from this, there is one at the bottom There is the chest, the rib cage, these bones, the ribs Cage. And there would be a muscle on the bottom side. This is what we call diaphragm. What Do you speak? There is a muscle which we They say diagram. This muscle that you can see You are here, this is a diagram. Now you understand The diagram looks like this. Now you inhale. Take a deep breath, son. Breathe in Take. That is, the diagram remains normally curved. But When we inhale, it straightens up. Is. It becomes flat. And when we excel If you do this, it becomes curved again. And this is the thing to remember. when we inhale If we do it, what all happens? First So the rib cage comes out. Look at the rib cage will come out. Apart from that, our diagram It becomes flat. It becomes completely straight. I told you. Apart from that, the chest There is cavity, that is, the size of the chest It increases mine. And when I'm at Angel What happens when I do it? Joe in Eggshell The rib is what goes down. what is a diagram It happens? It relaxes. diagram such remains. If I inhale it will become straight. It will become flat. Ok? MCQs on this It comes. And the chest cavity, that is, the part of the chest The size is reduced. Isn't it? Chest The size reduces at the time of eggshell. Did you understand this thing son? Tell me quickly. Have we understood the whole concept? Is? So let's look at some questions quickly. From. That will give you clarity. give the Reese's rings of cartilage are present in Throat. What do rings of cartilage do? Prevent Wind Pipe From Collapsing. That means what is its function? This collapse Saves. Lung Always Contain Residual Volume of Air. That means the lung has nothing The volume is always there. When you excel You give him a little bit even after that. It happens inside. Meaning there is air. all the 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 then my lung will get crushed. 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? To increase the size of the chest So that you can take in more air. Correct Is? Walls of alveoli contain extensive Network of blood vessels. Why? to exchange CO2 and oxygen. What is the plan? Alveoli has to give oxygen and take CO2. Ok? very nice. Is this what you understand? Let's see next. 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 what Multicellular organisms have their There is a lot of hemoglobin inside, which It is present in 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 does the alveoli work, son? Exchange of Gases. remember remember remember Do it quickly. How does he do it? and why are Alveoli richly supplied with blood vessels? Now See how Alveoli does it? 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 Diffuse 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 Joe Blood There's CO2, carbon dioxide, return that to He calls him to himself. Ok? Carbon dioxide from deoxygenated blood where But does it come? enters the alveoli. what happens then? Alvolai Eagle's Time But it comes out from the alveoli. in the lungs It comes and we egel. So this What is the whole thing? There is a process. Memory Keep it is varied. Isn't it? These repeatedly It has been asked how Alveoli works. Is. So, this is about animal respiration. 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, it's 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 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. They do exchange gases. How to do it? Look, son, first thing. I have already told you with the help of stomata. Ok? Apart from that, remember there are some pores. The plant has some pores which are called We call it Lenti Sales. their stem which The stem of a plant has some pores in it. There are what we call lenti cells. With their help they exchange gases. Are. Apart from that, generally with the help of root Surface of the root. Gases also with the help of root Let's exchange the . Why plant now? Exchanging gases? Two tasks. One So photosynthesis has to be done. Secondly, these too I have to do respiration brother. Energy for them You have to make it too, right? So this is also respiration do. Ok? Now here's a great one The interesting question arises that when the day is passing If so, the plant would perform both processes. Is. Look, it also does photosynthesis. It 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't because there is no sunlight. How will photosynthesis take place? So remember sir The plants that are there during the day Gives 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 happened, 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 one such question comes which of the The following statement is true about Respiration in plants? 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 Breathe? This is also a small question. The question arises whether fishes or fishing Breathing is the breathing rate that fish have His breathing rate would have been 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 more water again and again. so that it can extract oxygen from that water. Because he also has to do respiration Isn't it true, buddy, 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 had a lung Is. They have gills to absorb Disolved oxygen from the water? Now in this I am telling you the question that comes up. Am. Why Do Aquatic Organisms Have Faster breathing rate? Its a simple answer Is. Because water has less dissolved Oxygen. There's less oxygen, friend. in water, In comparison to air, then breathe again and again I will have to do it, friend. So remember to have them There is a specialized organ which we call Gill says. Let's go here now Respiration stops. And Let Us Start. The next topic is Transportation. Now we will talk about the heart from the heart. We speak our heart out. 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's summarize it once. what is nutrition Was? in which we had to eat food and Energy had to be obtained. How? We Start with the mouth. What was in the mouth? Salivary amylase. very nice. esophagus What came out of it? Peristaltic The food reached the stomach through movement. came again Stomach. What were the stomachs near? three brothers All three catastrophes. HCl, mucus and pepsin. very nice. Remember the work of all three. His Apart from that, the food was going down. only then He meets two goons. first thug Who was it? One was the liver, one was the pancreas. The liver does two things. The liver produces bile juice I had made it secret and done 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 attacked another The goon said to the pancreas that now I Three things will have to be done. So he used three enzymes Had released it. if you remember trypsin, lipase and pancreatic Amylase. Then the food used to go small What was there in the intestine? Vilay Finger like structure. that to eat Used to absorb it. And what was wasted From the large intestine into the large intestine In the anus. This was human nutrition. And Then we studied 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 vessel. And what is inside the blood? Hemoglobin, which is respiratory Pigment. What does he do? to oxygen He calls me to himself. With the help of which your The deoxygenated blood is returned It becomes oxygenated. So this is completed The entire story has been told so far. Now we move on There is transportation. Next Life Look at the process within transportation as well. There are three things. There are three brothers here. Too. Which brothers? First of all, if the brother 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. other than blood vessels From which this blood is going to go. And The heart comes last. Isn't it? And the heart said this I said it from my heart. The heart said this to the heart. Yours is getting 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 did not 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 we eat in parts Is. Who will work? These three brothers are here. There are people who will work. Heart is a pumping Organ son. Don't give your heart to anyone. and if If you have given your heart to someone, then see it. You You are considering her as Aayushi. what does he know Your friend Ayush sitting next to you should leave. 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 good hearted. Heart We will read about it in detail. majority Is. Let's start with blood first. blood What is it son? Look, blood is a type of It is connective tissue. In ninth grade, 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 color is red. It is red in colour. Why? Because it has a respiratory system inside it. It is a pigment whose story we have heard and discussed. Have taken. What is his name? Respiratory Pigment called hemoglobin. Ok? Which is It is found inside the red blood cells. So Before explaining the functions of blood, see The functions 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 there inside the blood due to which the blood moves What can blood plasma do? Whatever its color is, its color is like that It is a little pale yellow type. And What happens inside it? fluid medium Carrying Nutrients. That means this Nutrient waste, everything would be inside it. is inside the plasma. Ok? Now let's come Blood cells i.e. blood corpus cells. Two There are type K blood corpus cells. To you RBC will also know. Not RCB, but RBC. Ok? RCB fans yes WBC. Correct Is? So one is red blood cell and one is It is a white blood cell. Look at the red blood cells What does it do? We heard discussions 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 being used in transportation. Very Excellent. Next is the white blood cell. These In a way he is a warrior. What does it do? Protects our body. So Provides immunity boosters Antibodies against disease. fight disease It is useful for. And there is one more thing, the third thing Which is platelets. Variant. ever hurt If it had happened, 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 Getting platelets done. So this is blood All the work is there. Now can you do the function yourself? Can't you write about blood? blood functions You can write it yourself now. What is the first job Is the blood done? Look, the first job is done. What? To transport. Whose Transport? Oxygen Nutrients Carbon dioxide. very nice. Second low oxygenation, because the blood has It is RBC. near RBC Hemoglobin. hemoglobin binds oxygen Takes. 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. Next is Temperature regulation. of our body Blood also regulates temperature. Does. End clotting. I also had clotting I told you. Blood platelets Do clotting. These five points, son. Remember this. repeatedly asked in the paper Function of blood. And the children don't remember would stay. But you will remember. Why? Because you have studied under PK Bhaiya. No. Okay, this is about blood. Will it come now? Blood vessels. Three Types Key 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, son, I am telling you a trick to remember. of. Arteries means A is coming in it. and a There is another word from. Away away away. i.e These arteries carry blood from the heart. Will always take you away. That means this blood Where will you take me? Dil Se Awe Door Leke Will go. Vance has the opposite job. Vance They take us towards it. towards the heart She takes it away. What are capillaries? These Connects arteries and veins. i.e This is the middle path. This connects both. Ok? very nice. Ok? So this is for you You might 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 here's a There is an exception. Always oxygenated Blood carries. But there is an exception Which is the pulmonary artery. Pulmonary artery. very nice. Wayne also Always carries deoxygenated blood. That means dirty blood i.e. blood containing CO2. butt here But there is one exception, the same thing. Pulmonary Wayne. Ok? very nice. and the capillaries Carries both. Ok? Meaning Oxygenated and deoxygenated blood Carries the . very nice. Now look at the There is pressure, isn't there, son? Pressure in the arteries. It is very high. Blood pressure. Why? Because arteries carry blood away from the heart Are going. And how does the heart beat? Dhak Dhak Dhak dhak dhak-dhak. Isn't it? So when this blood is If you are taking blood with a lot of pressure, then It comes. The pressure is high here. Here, take it Take it there also. Ok? Remember the thickness of the wall Keep the thickness of the walls of the arteries thick Is. It is thick. It is thin and that So it is very thin. Now why is this thick? It happens? Because it causes high blood pressure Have to carry. If it becomes thin, it will burst. I will go brother. If the pipe is thin, it may burst. Isn't it? Yes very nice. The next thing is Valve. Remember Valve Are Only Present In ven. Valves are present in the vein. Now you will ask brother what do valves do? Questions have been asked repeatedly in this. Look son, this is your van. Ok? Now such valves would not have been present in the vein Are. Why do these things happen? accept the blood From your feet to your heart. Now such It is also possible that the blood may go down This means that the blood will flow in the opposite 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 and can get locked. i.e That blood cannot go down. So what is the valve? Are you doing it? Preventing back flow Are. And this was the question asked. valve These will help in preventing back flow of The Blood. Please mark the variant star. It has been repeatedly asked what valves do. Are? Why are they present in veins? Because they prevent back flow. Back Prevents you from leaving. Very true son. Correct Is? Did you understand the function? What do arteries do? Are you? Throughout the body, away from the heart. and this Blood is being brought to the heart from the entire body To. And the poor cafeterias are connected in the middle. Are doing. Is it okay brother? These things we It has been cleared. Isn't it? now over here Some useful thing has 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 Carries Deoxygenated blood. The only artery that It carries deoxygenated blood Pulmonary artery. similarly the largest vein It is called Vinakava in your body. 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 Let us now move on to the functioning of Heart. We speak our heart out. Now let's get to a very important thing. I 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? Sometimes you ask about it Are. Nowadays it is being asked less but you can ask. Are. I will show you with a simple diagram. Let me explain. Look, the first one is the heart. Heart Brother, there are four chambers. four chambers Make it. Ok? Take a look at the left side You have to look at the right side like this, son. left side right side left side right The side is okay, this is left, this is right, like this I don't want to see that brother, this is right, this is It is left, no no no, this is how it has to be seen There is left, there is right, okay, so there is one There is one left side and one right side, now this There is a God above, he has two names. It is either called an atrium or it is called It is called oricle, it has two names and it we say what we say this ventricle what do we call it They say ventricle, okay, this auricle or atrium these ventricles here also auricle or What will be the atrium or ventricle? Left Say. Left atrium Left ventricle. Right atrium right ventricle. Now watch the game Where does it happen from? Understand this completely Son. Flow chart explained with the help of a story Give. You will never forget. 5 to 10 minutes Will take. Look, this is your lung. accept this I am lame. What does Lang do, son? what is lang 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. So 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 blood comes out from here, come out from here It goes into the entire body. That means here There will be a body. So now that blood of yours is flowing Hey son, it is going all over your body. Is. It is going inside your body. Ok? Now what happened to the body? Respiration occurred, Carbon dioxide was released. Now this blood is back has become deoxygenated. Now this Deoxygenated blood, right? This is known where Will you come? It will come back here now, that is, right In the atrium. Go right from the right atrium In the ventricle. and from the right ventricle now Where will it go back to? This will go to the lang Near. And this cycle will keep going. Now the naming here is very It is important. I'll show you the naming Am. First of all, you should see this and understand the concept. Did you go? Oxygenated blood in the left side It comes and what comes on the right side? Deoxygenated blood comes in. 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 the help of this you will get the complete story easily. I will explain. Look who comes with 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 you come? Who brings blood to the heart? Wayne I will bring it. Which van will you bring? Pulmonary vein. Now from here the left ventricle Who will take the blood from the body? that will be One artery is the iota. then here Where will the blood come back from? Right Atrium In. Who will bring that? He will bring Veena To move a horse around in a circle. A type of vein. and then blood from here it will go back to the lung which Will take the pulmonary artery. Now this brother No one remembers. I have a trick Is. Now he has a trick, brother. See Let's see the trick son. a story to you I have to remember this. She was a badminton player. PV Sindhu. You must know. So look PV Sindhu has won no medals and Now he cannot video call his family members. I have to do it and show that look papa mummy If I have not won a medal then how can that happen? We will 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 arrange a video call for me And to whom did he tell this? PAs are PAs, aren't they personal assistants? etc. Yes, I told him that I told the PA that friend pv sindhu said ayo mujhe video Make a call. Who did you say that to? from your PA spoke. If you remember this then 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 Vina Cava Veena Kava Vinakava means VC VC very good And where is that blood going back to the lung? Who is going to take the pulmonary Artery means PA so means now from story Your entire heart could be destroyed. What did PV Sindhu say? Come What should I do, make a video call, whom did I tell I told my PA through a story. You should remember all the names now. Did you understand? very nice. If it is understood 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 septum. What is this? These There is a septum. What do we call this dividing ball? Are you saying son? Septum speaks. if you You must be seeing it clearly. Ok? His Apart from this, I have given you the complete flow. I told you. Remember one thing. Veena Kava Na Look, there are two entry points to Vena Cava. One is from the lower body. Veena came from here Kava and one from the upper body. That means one is upper Body one bottom body. The blood from both Where does he come from? We Minakawa Take He comes and goes into the right atrium. Is. Is this clear? very nice. Apart from this, there are some differences son which you You should remember this. What are those differences? First of the atrium and ventricle Difference. Ok? Atrium and ventricle. Well, what is the size of your heart? You know your fist so much. It's just so It happens to you. Yes. Your heart was so Is. But how important work does it do? so Don't give your heart to anyone. Ok? Heart is a must. Don't give your heart to anyone. Yes, okay. Understand in the atrium ventricle This is the upper chamber. This would have been the lower chamber. Is. Well, the walls of the atrium Son, they are thin. While the ventricle 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. He has to pump blood, right? Under high pressure. So that's why her walls are thick Should be. Otherwise the same situation will arise. will burst Heart and what? Ok? what do they do Son? The atrium receives blood and What do the ventricles always do? pumping Are. Pumps the blood. Ok? it This thing is very important. oxygenated Where does deoxygenated blood come from? These It is very important. I hope these diagrams You must have understood the whole thing. came or Didn't you come? This raises a lot of questions, son. Remember this. Oxygenated in the left What did I say? Left atrium, ventricle, right back from the body body Atrium, right ventricle, lungs. on the lungs your blood comes back from 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 and Deoxygenated Blood More Oxygen Will Be 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 as much It will not get better inside the body. so There are four chambers. Why? so that look oxygenated will be here and Deoxygenated will be here. So divide Went. Oxygenated Deoxygenated Divide Went. This increases our efficiency. ok brother very good. In addition, if If you have seen, 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? One bicycle is lame from the heart to the lungs and back again from the heart In. You can see from the lungs to the heart and From heart to lung. a bicycle. Second What is a bicycle, son? From the heart to the body And from body to heart. So here 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, right? 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, what is the pulmonary circuit? What is the pulmonary circuit where blood flows from Heart to lung and back, okay, one, this The first one is done, apart from that there is systemic We call it circulation or systemic circuit. what is blood flow from Heart part to the rest of the body and Returns. So what is this? This has been the second Circulation. Now these two circulations are important Why does it happen? your paper again and again You are going to see questions inside also. Son Today I am telling you that the question will come in the paper. Why is double circulation important? What is the answer? Let's see. Now what happens with double circulation? Is? Keeps the oxygen rich blood separated From oxygen poor blood. Insurance Efficient supply of oxygen to the body Maintenance high pressure in the systemic Circulation for proper distribution. Now What is happening with this? One is oxygen The supply is increasing. Second, each of our bodies parts of the body are able to get blood, Oxygen is available. i.e. respiration It is happening. 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 three I also wrote down the points that brother 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 our Can control body temperature. Isn't it? What do we call this? This we They say warm blooded animals. which we Are. There are many more organisms. Whereas Some organisms are cold blooded. whose blood does not control their temperature Those who can do it are called cold blooded. So All warm-blooded animals No, four chambers are very important for them. To be and to have 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, I can see your real heart. take a look today I also showed you his heart. Isn't it? No child should write this in the answer that Brother, why are there four chambers? four chambers Brother, boys, boys, four chamber address Why do they happen? One has Riya, one has I am Ayushi, one is Sunaina, one is It's Neha. No son, don't write this. Four Understand the logic of the chamber. Ok? Which Components of blood that help in clotting Does it son? Platelets do. Very Excellent. Next view of the following statement Is it true about the human heart? Of these Is it true son? Very good question. It 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 with a book Isn't it RD Sharma? So you remember Should always be in R D i.e. right Will come deoxygenated. So this is wrong Went. Let's move ahead. Left Atrium Transverse oxygenated blood to the left Ventricle. very nice. This is so perfect Is. Left Atrium to Left Ventricle transfers and from there to the entire body goes into. Who takes it? Iota. Ok? Let's see next. 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 atrium is that deoxygenated blood Who receives it? He does it. From where? Does he receive it? vena cava. anytime Remember this if you are confused. PV Sindhu What? PV Sindhu did 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 brother, 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 This was a good question. Next Assertion is for Reasoning Many questions are being asked these days. See The Wall The Wall of Atria. atria ie Brother, that is what atrium is. Ok? A Wall of atria are thicker than those of ventricle. No. No. The walls of the atrium are 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 to why D is coming. If If you haven't done it, then practice it. in the papers It is being asked nowadays. Next question level di Parts A and B in the Diagram of the Human Heart. Look brother, you have to see this. These It is left. This is left. This is right. This way Look at yourself son. Isn't it? is it 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 and Pulmonary vein. Look where the pulmonary artery is. But did she come? That artery which means lung From heart to lung. Look, it comes 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 thrombosis It brings you inside the heart. Yes. So that means What is? What does the pulmonary artery do? Deoxygenated blood. and what about the pulmonary vein Does it? carries oxygenated blood Is. It takes heart to lung and this It takes the lungs to the heart. Did you understand? fun Came? Is it going through your mind or did it happen? Brother, what are you teaching me? read something like this Whatever is understandable. Why can't I understand anything? Ok? It will come, it will come. This is a little It is something to practice. when you Because when you read it for the first time, you 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 the ventricles have to pump Blood with the Greater Force. Because of this I told him he had to pump it. Ok? Why Do Arteries Have Thick and Elastic Wall? Why are the walls of arteries thick? Because arteries have to pump? The blood that pumps He has come here, who will take him away from my heart? Used to be? Who is taking away? Arteries. So that means it is high pressure blood. This Because what would their wall be like? Is? It is thick. It is also written here Due to high pressure. Due to high pressure The main reason remains. Now let's look at the next one There is another topic. Like I told you that There are four chambers in our body. But everyone There are not four chambers. Like if I talk If I fish, look carefully. Fishes We also call it passage. Now this which Fishes have a two-chamber heart, right? Carries it. Yes. So what's inside them? It happens? Only singles in these Circulation occurs. And these are what we call Are cold blooded. Isn't it? Cold blooded. Ephebeans besides him. Ephebeans you know like your turter yeah I have also made a photo. Look at it. Your Looks like a friend. Look at this too Look, it looks like a friend. Yes. So It has three chambers. So this double Cannot circulate. Incomplete Double Circulation is doing this and this too He is cold blooded. Is it okay brother? temperature cannot regulate. Reptiles Joe There are also three chambers like Crocodiles are also cold blooded. And this is also completely double circulation. Can't do it. But birds, that is, abs and Mammals that is us. Birds means abs and Mammals are of two types. Who has what? have four chambers Are. Do complete double circulation. And What are they? 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 over. Evolution means 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 about anything inside it. Its You had to write the same answer inside. i.e Why Four Chambers Isnt. Why? Speak to Ensure supply of oxygen. Oxygen Body Supply will continue. In all parts The supply will continue well. Isn't it? So that's what you had to write in it. other than that Warm-blooded animals require Is. Isn't it? Check your temperature if they That is what you have to do to maintain control. and besides that oxygenated and deoxygenated blood To keep separate. Yes very nice. These It happened, right? Ok? ok that one in the middle The name of the wall is septum. which is in the middle of the heart There is a wall, it is septum septum. So That's why the blood from here cannot go here. The children must be thinking, brother, here and there Why are you not going? There's a wall in the middle 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 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 is a little difficult to understand. It is complicated. But why to wear one? Ke Bhaiya is here. See what happens? First understand what lymph is? Lymph. Lymph is called tissue fluid. i.e There is a fluid in the tissue. 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 things, take blood etc. They would be wandering here and there. But what about here It happens that some substances are leaked. Let's go. Isn't it? Leaks occur. As Some substances were 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, suppose I had a tissue in my body. Inside. There was a capillary going into it. This substance leaked from him. Isn't it? So What are many such substances? They leak accidentally. into Intracellular space. that is, between the cells There are species among them like this Substances leak out. Ok? So This substance that is formed there, which Fluid is formed and we call it that fluid There are lymphs. So how was lymph generated, son? Lymph generated due to leakage. So lymph Nothing is there When capillaries leak Things go away and then 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 leak out because of the capillaries? From. Now what things got leaked? anytime RBCs do not leak. RBC is essential. Isn't it? Because it has hemoglobin in it. Does not leak. But WBC never weighs. 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 whose name is lymph. Now this lymph There is WBC inside it too, a lot. All the proteins are there too. So he gets his blood back. I will have to bring it in. So back to Blood, who? Will you bring it? The lymphatic system will bring it. So That is, the lymphatic system takes this thing to the whole Pulls and comes back to the blood Come come and throws it in the blood. This is the lymphatic system and nothing else should come. Look brother, this is such a lymphatic that you You see the whole thing in green colour, right? There is a complete lymphatic system. Lymph wherever What happens if they are produced? One of their tubes is lymph vessels. lymph What do vessels do? pulling them and then puts it back into the blood Are. Ok? So 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 colorless come in? Capillaries Comes in. which joints to form Larger lymph vessels. Then it flows into the lymph vessels Reaches. This vessel finally opened into Larger vein. That means they went into the van. Reconnecting to the blood stream. from back It has come into the blood. Okay brother. Joe Leak It happened, it came back. It's okay now, it's okay now. 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 functions of Lymph? Look, the first function is clear. What? Transport of digested and Absorbed fat from intestine to blood. That means whatever digested food etc. It has also become leaky and it needs blood again. I have to bring it. First of all, this is obvious This thing is clear. Look at other work Drain access fluid from tissue. i.e What happens sometimes is that the tissues Too much water and some fluid gets filled inside. So the fluid that is filled in excess, right? It comes with the lymph and that too with the blood. Comes inside. like any harm to the tissue No, no. Don't get hurt. Ok? So access The fluid that is off also comes back into the blood. goes. Lymph contains lymphocytes. lymphocyte Nothing happens. What is WBC? White blood cells. And what are white blood cells? Do you do it son? Provides protection. So Is there another function of lymph? defend the Body against infection. That is, three lymph nodes Work. One is preventing infection Is. He is stopping us, saving us. The second is to bring everything back into the bloodstream. 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? Son, that will be enough for you. Its Let's see the question. 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 it. 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 the plant? Understand. The plant is also doing transportation. How is he doing? There are two ways. and this You studied it in ninth. But I know You did not study in ninth. I know Yes friend. I can understand. Something No. So there are two types. One is xylem. One is phloem. Had read. There were tissues. What does the xylem do? Water and Mineral Co Transports. phloem food Transports. This difference repeatedly Asked about xylem and phloem. Look at it. See what Xylem does? Conduct Water End Minerals from root to leaf. i.e. root to leaf I bring it. What does phloem do? Conduct food from leaf to all part. i.e Where is the food prepared? Formed in leaves. photosynthesis and is carried throughout the body Is. Ok? Second. Good Xylem Na Mainly Made of dead elements. you read What are the cells present in xylem? So these are some cells. if you remember You can, though it is not asked much. Trackyard, Vessels, Xylem, Parenchyma and xylem fibers. xylem only Parenchyma is alive inside it. Balance What are all three of these? Dead There are. This is why we call it xylem. Is composed of mainly dead elements. Whereas It is the opposite of phloem. What is phloem? Phloem is made up of mostly living organisms. 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 have been made of living things. Is. Now a big difference is coming. See Xylem transport in unidirectional So look at how the xylem transports it. Above the root, now that right, left, up, down He will not be able to do it in one direction It will be available but this phloem is by It is directional because the food is being made into the leaf. Now the food will go up and down from the leaf. If it goes in both directions, that means Transport in phloem is bidirectional Remember this has been asked repeatedly. The difference is very important, this difference Table is also asked again and again now the question It turns out 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 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 It's a thing. So, it is a very easy process. Which we call root pressure. gets upset It is in the water and it draws the water Due to osmosis from high pressure to low pressure The water moves in. second process It is very important and you have read it. I just read it a while ago. Yes Remember transpiration? what is transpiration Did it happen? water vapor 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 from 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. So why water from the bottom up? Will you come? Because high pressure to low pressure I will move. that is, transpiration Nor is this even for transporting water It is necessary. If there is no transpiration The water will not be able to rise up. understand this thing To? Yes. Ok? So I have given you two ways Tell me. One, 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 Ends move upward through xylem in osmosis 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 We have to know this process, we call it Ascent of Sept. Sometimes it is asked What is Ascent of Sap? movement of Water from root to upward direction by Xylem. Is called ascent of sap. Now look at two There is reason. What? One is root pressure. I Told you the root pulls and there's 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? right there Transpiration pull is taking place. Why? Because what is coming there? Take Pressure. Below is high pressure. So above It moves. Ok? So remember one of The work is pulling water upwards. And one more thing 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 water up. Very important role in pulling water upwards too It is about transpiration. Is it okay brother? Understanding Am I here? very nice. Now let's talk of phloem. How does phloem work, son? So See phloem food by the help of means Phloem carries food from the leaf to the He takes me 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 about eating Movement is what we call translocation. Are. Ok? Phloem Transport prepared food from leaves to the other Part of the plant. This process is called Translocation. Ok? Energy inside it is required because every Have to go in the direction. So it requires Energy. Did you understand? This is the bus in the plant. One is xylem, one is phloem. Xylem Mineral Is. And what is he doing? Yes, it is doing this It is food. very nice. Now, let's ask the question Let's see. which of the following statements Correctly Explain the Transpiration Pool Off the plant? Which of these statements Talking about transpiration bridge Is? So if you look at what's 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 Correct. Wow, my 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 it transported? what to him Do you speak? Just read it. Translocation. Is this it? You have become smart. Good This is a very sweet question. One about it 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 it? What type of process is he describing? If you If you look carefully at this diagram, you will see, What happened? Up here was Leaf. From the leaf Look at the water vapor and then look at the root The water started moving upwards. Water moves upwards 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? questions from this too Let's come. And look, I haven't seen that either. 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 remain confused, but you have to study. Friend, there were some children in our school. Those who had clarity that brother, we should study I won't do it at all, what would be the exception? Hey son, look what we read earlier is the injection had undigested food removed What is excretion, look, excretion is the Biological process of removing harmful metabolic wastes like urea and uric acid Acid from the body means as many Urea nitrogen is a harmful substance We will remove all the compounds. Correct Is? From our body. How is it now son? This diagram, this diagram is also repeated Comes to make it. You remember this Take. It is very simple. where the kidneys are 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 that These are the kidneys. There are two kidneys in our body 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 there, it will be 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? Blood came into the artery. Now there's dirt in this blood Is. Now the dirt inside the kidney will be cleaned. All the germs, worms, germs, speak 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 that has been cleaned. that blood will go back up 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 remains is access of water nitrogen compounds all these You see two pipes. these pipes There are ureters. What do you call them? Ureter. Ok? One is the left ureter. One is the right ureter. Ok? With the help of the ureter It comes here. And this is your urinary Bladder. What you see inside your urinary bladder You store your urine. and expel it with the help of the urethra. You give it. Ok? So what is flow? kidney. There was blood in the kidney. Made a mess. dirt Ureter, urinary bladder, urethra. Below What did you do? Whatever you give to whomever you You call it urine, there is nitrogen in it. There are compounds. Access to water 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. You can pass urine through the urethra. You throw it out. Now everyone has one thing on their mind You might be wondering, brother, this diagram is for us. I will remember it. Not that difficult a 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. you Do you remember what comes from the heart? from the heart What will come? Iota comes from the heart. So this The iota is the division of the renal arteries Inside. These two little ones are going, Rinal There are arteries. The big one is iota. and which This big one is taking it back, isn't it? 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 Vina Kava take me? Towards the heart. Where will your heart take you? Right. Right. Right. Very true. Okay, I understand this. Now Let's talk about what is happening in the kidney brother. Is it special? What is happening in the kidneys? So Nephrons are in the kidney. what is a nephron Is? Nephron is a structural and functional Unit of Kidney. That is, the kidney's most 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 the story of Step. This is a diagram brother You should try to remember. If asked I have been there very few times. But look, try 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 this on this portion like this Have to focus. Isn't it? This one in yellow It is a complete portion. This is just you The force has to be focused. Ok? Now I Let me explain how. Look, blood has come. Three There are stories, it is in three parts. means three There are steps. I am telling you How does the nephron filter blood? One There are millions of nephrons in the kidney. 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 we 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 take. And as soon as When he ate that capsule, he started glowing. Started glowing. Started glowing. He said Ok. Now this is our first step. As As soon as the blood came in, this is what you can see. Yes, we call this Bowman's capsule. What Do you speak? Bowman's capsule and the Bowman What is inside the capsule? glomerulus And what does this glomerulus do? Glow Glow That means it started shining. That's why I said glow Glomerulus. And what does this glomerulus do? Is? Does filtration. That is, the first Filtration happens here. It pulls all these things. as much as blood There are also dirty things, he will take them all away Inside. And he puts it inside himself here. Is. Ok? Now the blood speaks, hey thank you Dude glomerlos dude. well i'll go My work is done, friend. So now watch the blood go Seems like I am going I am going. Then the blood I realized the blood. I La Scam Ho Went with me. So brother, it was a scam. So How did the scam happen? Dude, that was the glomerulus No, I said yes, yes, he knows what Kara? I said tell me. He did not mine All the good things I had, like my I took water, my proteins, that too. 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. Now look Glomerulus is a good man. Now when he When I go back, look here, this is what you roam around Can you see what's going on 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 blood. Ok? Now blood speaks Hey, thank you friend. Well, this is the whole thing The loop travels and the blood flows from here goes. Now what is the third step? Now all that all the dirt has come 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 this We call this process tubular. Secretion. That means, whatever amount of dirt there is, We finally remove this dirt in the form of a tubule. Put it inside, that is, inside a tube. And this is what we call tubular. Secretion. So look son, there are three parts. You can remember the whole thing with the help of the story. 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 and Access Salts are filtered out this initial filtrate Enters the Bowman's capsule of each nephron. Ok? What happened in the story? came first Bowman capsule fed you will not welcome. 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 just remember this. Headings You will make the inside one. you so much There is so much art within you. I know you make it, Glomeral. Remember filtration, next step selective. I told you about reabsorption when I was with him. If he was cheated, what did he say? He backed down. I asked for my things back okay edge di Filtrate moves, that is, when the blood moves forward Looks like the nephron is useful Substances such as glucose, amino acids Salt and significant amount of water Reabsorbed means it asks for it back. Okay, now the blood is gone, what's left now? Tubular secretion comes last i.e. urea, additional water and excess salt are secreted into tubules, i.e., as many There was also dirt like urea etc. excess water. All the tubules that make up the collecting duct I told you about the collecting duct inside it. It reaches there. Ok? which then opens Into collecting duct. The Urine Than Floss From collecting duct into ureter. i.e Now look where it will go from the collecting duct? Where did the blood from the kidney go? Ureter. Urinary bladder urethra yes so three catastrophes How will you remember the three brothers and the three destructions? GST is applicable on everything these days. Pay GST Global Filtration Selective reabsorption and the final is tubular Secretion What's up guys, let's ask some questions. Yes, isn't it, so this is the entire process. I told you, you can see it here. Yes, how was urine formed, son, how is it? The entire process of urine formation will be explained to you. Told okay then urine transport Who does the ureter, who does the storage Is it son? The urinary bladder does. And Where does the final excretion take place? Excretion occurs with the help of the urethra. From. When we feel that no, no, no, now So friend, oh brother, I will have to go. Isn't it? Yes. Then with the help of urethra we expel urine. Let's 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 Does filtration do it son? 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, it's been asked again and again. How is urine formed? So not inside it I will tell you the complete process of nephron. Is. I want to tell you that blood is It came to the kidney. The kidney had nephrons. Now There are three steps in the nephron. GST, Glomeral Filtration, Selective Reabsorption and tubular secretion. So You will find this entire process here. I have to tell you. Ok? Explain the Basics Process of urine formation. Then you complete Will you tell me the complete process? I mean the same three You have to explain the entire step. Correct Is? State the function each of the following 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 that 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? Sters. Stores Urine until we urinate They would have done it by storing 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 brother. Yes, okay. Write One Specific Function each of the following organs in relation Of Excretory in Human Beings. Ok? Renal artery. What does the renal artery do? Is? I have brought the artery from the heart. Whose On the side? Towards the kidneys. This is what is in the kidney They have blood which has impurities. She brings it. i.e. renal artery caries di Toxic blood. The blood in which toxic substances that bring it to the kidneys Is. Urethra: You urinate. glomerulus What is happening inside it? There is filtration Used to be. tubular part of the nephron What are you doing? tubular secretion Used to be. Isn't it? as much as tubular secretion Our urine is also formed by collecting goes into the duct from here and collects 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 Secretes additional waste into filtrate. That means what is its main work son? understand that This is the tubular part of the blood. The dirt had arrived. other things in that mess Adds it. such as extra water, Glucose and all that. Ok? So one of its What else is there to do? That it adds it. Memory Is it 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 is inside it He puts it in. Ok? very nice. What Did we understand this entire story, son? Where can I find these notes? children are asking Are. You will get the notes, friend. So much load in the 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 One of the kidneys gets damaged Seems like 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 have kidney failure Is. To clean their blood, Let's use the process. whose name is Hemodialysis. dialysis means blood To clean. Ok? Ok? So the machine's With the help of this blood is extracted, clean and the blood is injected back in Is. Let's look at a question, son. Its. What Will Happen If the Kidneys Stop Working? How is this condition treated in Hospital? If the kidneys stop 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 be formed and ultimately death will occur Will go. Now how will this be solved in the hospital? It happens? One is dialysis. hemodialysis which I told you about and The second process is the kidneys Transplant. These are two processes. One is dialysis and one is kidney Transplant. What is it with the help of? These Can be solved. Let's do one last The topic remains which is Excretion in Plant. Then this chapter is ending. I know you are tired. I am not tired Am. How did you get tired? I will kill you. Yes. get tired Not there. Let's excretion in plant. See Do plants also excrete? Yes Let's do it brother. How to do it? Firstly he Carbon dioxide is expelled. Takes out oxygen. Isn't it? Obviously It's a thing. So first of all oxygen and carbon Dioxide is diffused through stomata. That too is a kind 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 Let's leave it outside. Is it okay brother? I understand Went? next. Plants Can Even Lose Some of Their old parts like old leaf and Bark of the Tree. That means what happens? it Your old leaves that become They also start dropping. good one very good The concept is to be understood. Plant your waste are stored inside the leaf. leaves Store inside. Do you know? That you see the leaves fall Do you know why it rained? Because Inside them was the plant's waste store. Yes. So plants store waste. leaves inside the leaf and then shake them off Are. Let's get it shed. Ok? Other West Produce Like Other Weight Products Like Resin and gum especially in old xylem Sales which can also be lost by a plant understanding you have seen something There are plants that have a stem Some of the plant's gum-type nickel It has been happening. Glue type thing was coming out Is. Have you seen the rubber coming out, do you know what? Is? That's all plant waste. yes then Plant means removing its waste like this too Are. How? Forms of like resins and gum In. And the last plant also secretes some West Innu di Soil. That means even inside the soil What do they do with their waste particles? Are? Let's release it. So the plant never If you ask how the plant excretes Is? Does the plant excrete? Yes, Does. Gas exchange removes water Extracting gums and resins from the leaf stores it in and drops that leaf Is. And with the help of the routes that are there, What does it do to the soil also? Xcrete Does. Ok? very nice. So this It was a complete process. You can see this yes. You must have seen this big tree. Is. Something like gum comes out of it. what is it then? That is waste brother. They It is waste. But it is useful to us. They It's 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 acids 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. The one I gave you in my heart I explained that I should not forget it. He doesn't forget Is. Isn't it? once again the emphasis inside the mind Put it in and tell me what it was? PV Sindhu Ne bola 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 my family members. What Did he say that? Yes. Yes, I told the PA. Remember that was pulmonary vein iota venacava and lastly the pulmonary artery. There is as much flow as there are questions. I could have done everything I guarantee I can say this is one of the best ones Shot outside this not inside your paper It means it will not come, this is PK Bhaiya's It's the tongue. Isn't it true that words have value? Correct Is? And if you ever feel demotivated like this If you feel like this, remember one thing, friend. Ki Na was a great basketball player. I saw one of his interviews and He said a line, you know? The day before the basketball match I know What I do is I imagine myself I imagine myself scoring a goal basketing while basketing I imagine I'm doing baskets Just Why Power Lies Here in Your Mind your powers if you feel like it Your marks in the exam If they are not good then they will not come but if You seem like you're very If you come with a great score, you will Will you come? Power is here. 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.
