hi everyone this is blah but we're going to do today we're going to go over the diagram that you received in class on Thursday if you don't have a copy of this I posted one of them okay so in the diagram this is a diagram of the heart there are four chambers of your lunch and flat they and these pavers I can be labeled structures 1 2 3 and 4 what you notice when you're looking at the diagram everything here on the right side of the diagram on the right side of the heart appears on the left side of the diagram and everything on this side heart this is the left side of the heart is going to appear on the right hand side of a diagram so everything's kind of backwards it when you're looking at a diagram the width that I just wanted another thing to point out everything here on the right side of the heart the right side of the heart it's going to be deoxygenated blood and everything here on the left is going to be oxygenated blood let's go over these structures 1 2 3 and 4 all going to be the chambers of the heart structure to structure 3 and structure for one and two are on the right side of the heart he's going to go ahead and label on the top chamber structure 1 and do the right atrium of the heart underneath that structure to is that something that's going to be the right ventricle on the other side of the septum is this wall that separates right here that's going to separate the right and left side of the heart it's on the other side of the septum on the left hand side of the heart we have structures 3 and 4 if the structure 3 Zonda on the left atrium structure for is going to be that left ventricle I noticed things I mentioned in class on the do in class when I do it on the board I kind of made all the chambers the same size I said in reality that's not the case I hope you noticed the left atrium of the heart is much left ventricle of the heart sorry is much bigger than the other chambers of the heart left ventricle significantly significantly larger rather than the other Chambers everything has to be today that has to pump the blood all the way down to your pinky toes and still have enough Force to bring it all the way back go back to our diagram AC now we have structures 5 6 785 is right here in between structures wanted to structure 5 is that valve that separates the right atrium from the right ventricle structure of five it's going to be a try all of the tricuspid valve on the right Home Depot right here and be structure that's the right AV valve structure six eight is separating the right ventricle from the big arteries that are tearing blood away from the heart structure 6 is going to be our pulmonary semilunar valve on the other side of the heart we have structures 7 structure 7 is separating the left atrium from the left ventricle the structure 7 is going to be at 5 structure 8 on the dime iPhone 8 on the side Section 8 that's going to be the aortic semilunar valve but then again so let's look at the vessel there are two big things on the top and they going to carry blood to the heart and there's two arteries on the bottom of the ventricles blood away from the heart so if you look at the structure in line on the diagram Sector 9 here and there's another structure 9 here a structure 9 Those About to be the vena cava vena cava structure 9 their two of them one is going to be inferior vena cava bringing blood on the bottom from the level below the level the heart this right here would be the inferior vena caval this one up here that's going to be the superior vena cava all the deoxygenated blood from everything above level arms in your head and your neck if you look at structure number 10 way from the heart now structure 10 is it going to be the only arteries in your body that contain deoxygenated blood these are going to be a pulmonary artery and the reason they are arteries blood away from the heart going towards the lungs and going towards the long to get oxygenated if you look at structure or 11 or 2 structure 11 it is 11 over here and there's 11 over here pay structure 11 on the diagram those are going to be the pulmonary veins structure 11 it again there are two of them coming from though because there is there veins coming from the right and the left let's look at structure 12 structure 12 if you noticed it's really large and large loop on top and then there's another big expansion coming down here both of them are the aorta structure 12 if you think the largest most important artery that you have in the body is the aorta and the difference right here is that this part of the aortic pull the aortic Arch and you notice that there are several little branches coming out but these are arteries that would be sending blood to your arms in your brain and the aortic Arch continues along the posterior part of the heart cuz you don't really see it in your heart and then you see it kind of poking up here this would be the abdominal aorta again a big giant big giant vessel that sending the blood to every else below the level for heart and like I mentioned in class this is a large artery in your in your body pays absolutely tremendous success can be asked about it and it is quite large blood is going to answer the heart through the Atria and structures 1 and 3 dr. Juan is receiving deoxygenated blood structures 3 is receive oxygenated blood when the Atria contract the AV valves need to be open for the blood and go down into the ventricles when the ventricles contract the blue then going to be forced out of the hearts with a pulmonary arteries from the right and the big giant a weirdo on the left hope this was helpful have a great day
