[Music] blood circulatory system let's go [Music] welcome back guys so there is the material for you to download in the description box below help yourself so blood circulatory system so my my my goal today is to help you to understand the flow and the story and also the labor links okay and we'll try out some exercise now first thing first you have to know all the 13 labelings that we have for your heart okay i'm just going to go through it very quickly and we want to focus on the steps or i should say the flow of the blood instead okay so first thing first we have four chambers of the heart so i'll call it as four chambers of the heart so we have um up down and left right so let's cut into a cross line okay so the bottom part will be what we call as ventricle so we have right ventricle and left ventricle so remember um when you look into bulk or exercises or like notes like that it will be the opposite of what your real heart is so this is the right side but it's actually on your left side it's the opposite because if you turn your book around and put it onto your chest that's the correct side of right and that's the correct side of left so it's always the other way around so right ventricle left ventricle on the top part is what we call as atrium so we have left atrium and we have right atrium as simple as that okay that's the first four second four will be your um valves so we have four valves okay here we go we have buy could speed wealth try cool speed wealth sorry my mystic buy could speed wife try crispy waffle and semi luna both on the top which is the same name okay so remember try could speed is on the right side so hence this is how i usually used to remember try right truck try right right try right right right side track that's why i remember so the other way the other one will be definitely by cosplay one so that means i remember one so the other one is just the opposite okay i know it's lousy right but that that's how i used to remember okay right um next we have four blood vessels okay so we have the biggest one ayota okay and then we have pulmonary artery and pulmonary vein on the right sorry on the left side on the right side of your view okay uh they are called pulmonary because these blood vessels are connected to the lungs so the lungs are called pulmonary so like these are the blood vessels that goes to the lung and come back from the lungs to the lung from the lungs so pulmonary artery to the lung pulmonary vein from the lungs so that's how you remember okay and we have vena cava superior and inferior but it's okay we will just call that as vena cava uh which is on the right side okay right so four blood vessels vena cava aorta pulmonary artery pulmonary vein the last one will be septum which is the wall that separate the left side and the right side of the heart okay the wall 10 no problem right these are very basic yeah 4.1 4.4.4.1 in total we have uh 13 labelings to remember okay try to go through that a few times i'm pretty sure you can hence i have one question for you to fill up all the names of the parts for you which i'm not going to do it so you can help yourself and refer to the picture okay just to give you a better idea of how the whole structure is let's get into some animation everybody okay so you can see this on your screen right right so i think we will start with the first four the first one will be the rooms and the chambers that we have so uh starting from maybe this one okay so this will be on the left side by the way remember is on the other side of your real your view okay so this is on the right side uh it's on the left of the heart okay so this is called the left atrium get a better look from behind left atrium okay right then you have your right atrium get a better look from behind right atrium this is on the right side of the heart but from your view is on the left side right okay then we have the ventricle at the bottom so this is a cross section so this part oops yeah okay this part on the inside the lower part that will be your left ventricle and this will be your right ventricle so four rooms there you go the second four will be the walls so there you go this is on the right side right right right right tri crew speed this will be on the left side by could speed well the name try truly try for tree because there is three sides if you realize there is three flaps or three layers that you are seeing here why we call bi because if you take a closer look there is only two it's not three sides all right this is two and this is three you can see right it's a triangle you have three sides of it so try cruise speed oops buy cool speed okay oh come on bye crispy okay and semi luna wife both on the top take a good look here semi luna semi luna okay semi luna semi semilunar no problem okay cool then uh we have uh four valves done right the next thing is we have four blood vessels okay so this is the largest one ayota right this is to the lungs pulmonary artery to the lungs okay and this back from the lung pulmonary vein back from the lung okay and then we have vena cava obviously on the right side here okay let's turn around vena cava from the top okay and then i cover from the bottom yep okay and lastly will be the wall at the center which is the septum okay so take a good look again in 3d okay there you go we'll be back for more later yeah okay next let's talk about the flow shall we right i have already constructed a table here so take a look at the table these are the flow following the number so the this one on the orange orange title i should say like a red title represents uh the red color blood vessels as well okay which is what i call as oxygenated blood the side where we involve in oxygenator or i could also say this is on the uh left side of the heart this is happening on the left side of the heart okay and you can see the blue title here represents the blue blood vessels which is also deoxygenated which represents the right side of the heart okay so we split into heart this is the right side is the left side okay right but it has nothing to do with the real left and real life uh real left and real like right side this is just to show you uh to split into half so it's easier for your understanding okay right so first thing first let's start with number one pulmonary vein which is where blood coming in from the lung which is obviously oxygenated blood okay uh from the lung under the heart that's number one so let's make it short and simple don't have to memorize a long one you just have to remember the important keywords okay and and the flow yeah obviously so oxygenated blood from the lung um comes back to the heart right then the first place to enter will be your left atrium this one left atrium so left atrium will contract will push the blood down one so oxygenated blood is forced to flow into the left ventricle which is the bottom part forced to flow into the left ventricle you can follow the arrow as well like that okay but it has to go through this waff called bicuspid valve that allows blood to flow in one direction from the left atrium means the top to the bottom cannot uten cannot go back okay that's the job of the wife which is to close up so that the blood does not return when the left ventricle contracts yeah you because when you contract the blood is probably splashing out or pumping out in all direction so you don't want the blood to return this way you want the blood to go up this way okay so hence that's the function of bi crisp speed wife right so uh then next uh in left ventricle left ventricle will contract oxygenated blood uh flow into aorta which is the largest blood vessels okay that is uh going through semilunar remember just now i'll show you semi lunawaff which is to prevent blood from coming back there is a waff here you do not want the blood to return to the left ventricle you want to go all the way out you do not want a u-turn of blood into your heart okay so that's the job of semi-luna what right last iota that's to transport oxygenated blood from heart to all parts of the body except for the lung so from here right blood will go all parts of the body and come back to the heart so hence quickly to show you the double blood circulatory system as human we have two circulation so this is where the oxygenated blood goes to the whole body okay and that's when you um release oxygen into body parts and then the blood that comes back will be deoxygenated blood okay we'll come back to that if we need to ask for now you guys okay with this one which is the right side of the heart okay we won't get into the left side of the heart yeah so now once you have gone to the whole body sorry wrong drawing whole body to release oxygen and then that relates to your previous chapter which is chapter 2 which is respiration after you release oxygen then gas will be collected in the blood carbon outside gas will be collected so when carbon dioxide gas is collected it will be transferred back to the heart yeah so when transferred back to the heart it has to go back through vena cava through vena cava so here we are now okay from the whole body back to the heart into vena cava yeah so deoxygenated blood from whole body back to the heart number seven okay enters to the right atrium this column okay this chamber so blood comes in here and being pushed down to the ventricle okay so right atrium contract deoxygenated blood flow into right ventricle which is the bottom through what through the wall again uh trichospite wife which is to allow blood flow in one direction i don't want the blood to go back to the atrium no no okay so flow in this direction okay that's the job of the uh tricuspid work yeah okay next now we are in the right ventricle which is the bottom one same thing it will contract deoxygenated blood vessels blood with the oxygen means full of carbon oxide will flow out to the pulmonary artery remember where is that pulmonary artery yeah from here go out to the pulmonary artery which is going to the lungs yeah but passing through semilunar which is to allow blood to flow in one direction i don't want the blood to return yeah into the ventricle okay pulmonary artery which is the one that transport blood to the lung deoxygenated blood uh from heart to the lung okay to carry out the gaseous exchange which is respiration topic which is the previous chapter if you're interested you may click the link below or above somewhere to um learn about the previous topic yeah okay cool that's the whole sequence try to go around it for a few times then i'm pretty sure you will get into your head it's just like a flow of making cake you have to just repeat to wing it you'll be familiar without the recipe right so uh from 1 to 12 keep going through the flow you'll be okay so final thing right uh this is called double blood circulatory system means we have two circulation as i was mentioning just now so blood oxygenated blood from aorta which is an artery a type of artery go to the whole body to distribute oxygen once you finish distributing oxygen that means you collect carbon dioxide becomes the blue color which is vein coming back which is vena cava a type of vein yeah and the ventricle will pump the blood up which is true pulmonary artery which is a kind of artery to the lungs which is to do gaseous exchange carbon outside throw away oxygen collect then the blood is called oxygenated blood again come back through the heart called pulmonary vein which is a kind of vein so the best way to differentiate which is arterial which is vein usually vein means blood coming back to the heart come back come back it's called vein yeah so we have one vein two vein two veins are to the heart to the heart of course in your body there's still a lot but i'm just talking about the heart right now and we have artery means going out of the heart out of the heart also called two so two uh vein there is two artery at the meantime okay no problem so yeah there you go pulmonary circulatory system is the one that goes to the lung come back to the heart go to the lung come back to the heart go to lung come back to the heart okay yeah this one and the other one is called systemic circulatory system systemic means to the body systemic means to the body from the heart to the body from the heart to the body from the heart to the body this is called double circulatory system so in this part you must know how to label which is systemate and which is uh pulmonary pulmonary means the lung remember pulmonary means lung so it goes to the lung and it comes back from the lung okay cool i think we uh final thing we try out some look out some animations to get you to understand the whole thing again okay so uh first of all i think i'm gonna give it at a 80 bpm just to let it just to have a look of how the heart is being pumped okay guys no problem yeah yeah okay so uh if we have the direction take a look everybody take a look okay okay let's make it slower for everybody to take a look yeah so blood comes in through this this part yeah uh which is the atrium left atrium and blood comes in through atrium into the ventricle what you're looking at now see the arrow is coming in through the bicuspid waffle and when the ventricle pump right the red color yellow arrow goes up do you see that the red color run focus on the red color go up to the semilunar this one se mi luna agena go up okay so come in go up there you go so where this goes to it goes to the a uh aota which is the largest blood vessels that distribute blood to all parts of the body okay so after you go to the body distribute all the blood then you come in through vena cava so take a look at vena cava which is this part look at the arrow is coming into the atrium to the right atrium and then it comes in through try cool speed what do you see that trick speed one look at the blue color arrow everybody blue color arrow okay and when the right ventricle pumps blur okay look at that when the ventricle pumps blood look at the blue arrow it's going up to the semilunar okay it's going up to the semilunar so that so seminar opens up and blood goes through this blood vessel which is pulmonary artery which is to the lung and then gaseous exchange at the lung and then the same story comes back uh pulmonary vein which is this too little hope into your atrium okay maybe let's have a final look of the whole thing yeah oh maybe let's add on the blood there you go right shall we add on the heartbeat maybe here you go okay this is this is 76 beats per minute right let's let's maybe get up to 100 that's the max i can go i'm sorry that's all i can show you okay this is 100 probably almost like uh um like jogging maybe slow walk to jogging okay it can go up to 120 if you run yeah but at the moment this will be how it works okay cool let's get back to our notes please turn with me to this page or you download it and you print it on yourself okay now to fill up the blank is for you so i'm gonna leave it for you to practice i will go straight into the next part which is b shall we okay so question b says draw blood flow in the heart with arrows okay blood flow well this is a flat um flat view lah it's not like the one that we see in the animation uh especially the blood vessels are not as what we learned just now so this is almost flat into like that okay so atriums atriums ventricle ventricle so blood comes in remember from the lung to the pulmonary vein so blood comes in this part okay so by the way this is pulmonary vein yeah okay so blood goes down through the wall which is called uh bicuspid valves and go down to the ventricle so ventricle will contract and blood is pumped upwards through the semilunar wall and all the way up to aorta by the way this is a okay and it goes to the whole body to distribute oxygen collect carbon dioxide and then come back through this part okay so from here this is your uh when i cover vanna cover okay and then goes through the tricuspid waffle this area is a waffle it's not so obvious but it's there okay so then comes down it pumps up through the right ventricle through semilunar waffle and this is pulmonary artery yeah if it's a flat view why is that that one they draw num num for four blood vessels two in two up but if you refer to the real structure right it's it's here it's here this is this is out this is into the atrium and then from here to aorta to the whole body it comes back in here okay then from here it connects to this to the lung and then lung comes back yeah so it's a different view make sure you um get familiar with that so there you go you don't have to label the names it's just me labeling for you to see so this is the direction of the blood flow okay so name two blood vessels which carry oxygenated blood so oxygenated blood it has to be on the uh left or right think about it based on this one which is the red color one of the red color one but exam no color you have to know okay so we'll be on the left side of your heart remember so left side of the heart the blood vessels will be aorta and pulmonary veins on the left side yeah because pulmonary artery is the blood vessels that carry deoxygenated blood to the brain to the sorry to the uh lungs and collect oxygen back to the veins again so there you go your answer will be iota and pulmonary vein which is two blood vessels that carry oxygenated blood this is to the body this is two this is from the lung okay this is two body this is from the lungs okay all right right two blood vessels that carry deoxygenated the ego deoxygenated will be on the uh right side of the heart yeah so we have pulmonary artery and vena cava so pulmonary artery is two lungs this is from body by the way just to let you know okay which chamber of the heart has the thickest wall thickest wall okay take a look at the picture here you can kind of recognize this very fat wall uh remember that has to be your left ventricle why because it's like um you know you have a dominant hand or a dominant leg or a dominant muscle you've been using it for so long hence it will be larger than the other side so that particular chamber which is left ventricle is always pumping so strongly so that the blood can flow from the heart to all body parts so hence it has to be very strong whereas the rest is this to the lung come back from the lung come back from the body so the really strong one is the one that always pump blood to the whole body that will be your left ventricle because it pumps oxygenated blood to the rest of the body that's why it makes it so strong and it has to be strong at the meantime okay next what is the structure that separate left side and right side of the heart obviously septum easy structure that separate atrium and ventricular oh atrium ventricular is up and down though so up and down will be the valve i guess the walls that separate the top room and the bottom room yep there you go so walls yeah you you can be specific on the names but you can also just write wow understood okay no problem cool next question shall we question number two label the blood circulatory system figure figure using the words below so given systemate and pulmonary so systemic will be to the body right pulmonary means to the lung right so you know pulmonary has to be on the top line this is to the lung come back to the heart from the heart to the lung come back to the heart okay if you want to you may refer this as well this is pulmonary circulatory system okay cool let's label in the picture so maybe let's do this okay so this will be systemic circulation okay okay right so the other part will be the lower part i guess that will be oh no my bad sorry that is not systemic okay question number two shall we right uh label blood circulatory system in figure using the words provider okay systemic and pulmonary okay like if you need to please refer to this so pulmonary means the upper part to the lung sun okay and systemic basically means the lower part which is to the body yeah okay let's do this so on the top part maybe let's label on the outside okay that will be your pulmonary circulation okay on the bottom part okay that will be your systemic circulation okay there you go no problem yeah okay next one on the freedom uh given label position of the oh so there is three things to label position of the lung left ventricular and right ventricle okay position of the lung you all know it's on the top layer so from here let's just label how this is the lung okay and then left ventricle and right atrium so left ventricle the left side is actually the right side of the picture right uh left ventricle which is the bottom part this one left ventricle okay and then next is asking for right atrium right atrium atrium is the top part so here right atrium okay is that all yeah cool number two show the direction of oxygenated blood flow with arrow ah oxygenated blood flow yeah just oxygenated not the deoxygenated well of course uh from my screen here you can see the color the red color oxygen but an exam don't have so you have to remember oxygenated must be on the left side of your heart okay so let's just use uh okay i'm just gonna use black color pen to show that so from here iota out to the body okay and then from the lung in to the heart i mean you can draw on to the the blood vessels but i think difficult to see also so i draw on the outside no problem okay easy cheesy that's um b2 okay c what is the name of the blood circulatory so human we are always called double because we have two sides the systemic on the bottom and then the pulmonary on top so double okay that will be double blood circulatory system okay explain briefly how oxygen arrives at the heart it's from the lung okay and then reaches the cell of your kidney so you see the flow will be lung to heart heart to kidney okay that's the flow by the way yeah okay so like oxygen from the lung diffuse into blood capillaries and carry through uh to the heart so there you go that's the first part okay the lungs into the heart through pulmonary vein yeah i have to be very clear of all the names of the blood vessels yeah if you are not too good at that please make sure you go through a few times then oxygenated blood leaves the heart through aorta distribute to the cells of the kidney so there you go these are the story so you can make it simple you don't have to form very complicated sentences as long as you have important points yeah oxygen diffuse into blood capillary okay in the lungs that's your first story next story from the lungs heart will carry oxygenated blood through pulmonary vein and enter the lana i enter the heart by the way exhibit the lung enter the heart pulmonary vein okay oxygenated blood leaves the heart that's your third part already oxygenated blood leaves the heart through aorta and it goes to the cell of the kidney okay question e what substance are transported from by your blood system from small intestine to your heart from small intestine to your heart oh if i were to ask you uh as you are blood ask you to go to the small intestine to pick up a bustle do you have any idea of what you're picking up that depends on where you're going because if i ask you to go to swan testing then you know oh small destination small testing is for digestion one or food one or i i think i'm going to pick up food la i don't know the heart didn't tell me it just asked me to go and pick up so i'm guessing i'm picking up food yeah it depends where you're going to if you're going to the lungs right then of course that's where you pick up oxygen and you throw carbon outside right okay so digested foods such as glucose and amino acid this is from your form two chocolate trilla digestion what is transported from the lung then you go lung to body cell means if you were to ask to go to the lung to collect something and pass to body cell you must be collecting oxygen vice versa from body cell back to the lung that means you are asked to throw away the carbon dioxide from body cell back to the lung okay cool no problem now i have one little work for you which is to fill up all the labeling make sure you are good at the labeling first and the names then this box will this box will seem to be a lot easier for you so in sequence please make sure you get to remember the flow yeah cool i guess that's it for today i hope the video helped uh if you have any questions you can ask in the description box below alright maybe consider to subscribe share to your friends and give me a like i will see you in the next video bye guys [Music] [Music] [Music] you
