Anatomy and Physiology 232 Lab – Blood Vessel Practical



so the main vessel that's going to supply the body is in your little a or a pound and here's the aorta so it's a fairly substantial artery going down as far as yet there are four sections of it the first section is the so called ascending aorta because it's going upwards for just a little bit of its length the only thing that actually comes off there are the only two things are the left and right coronary arteries which aren't even shown here so italics and brackets means that you can't actually see them but they're important enough to mention so they're literally the first branch is off sometimes a little question in one of the quizzes what's the first branch off the aorta so the coronary arteries are the first branch and then we have the ascending aorta here pretty hard to actually put a pitch put a little tag on the ascending aorta and really make it look like you didn't mean this part here which is the aortic arch so Molly wouldn't bother where this fish numbers we can't see the coronary arteries come up but there it is s then this part here is the aortic arch with three vessels off it so I could put it there then you put a or Tkach for number whatever that is 7 and then the descending aorta is generally divided into two the thoracic aorta above the diaphragm and the abdominal aorta below and you might think that's a lot of parts of the aorta but I was telling everybody earlier about the importance of putting the vessels and the well I don't think about it like but anyway let me just talk about it you get over this noon so there's the aortic arch off the aortic arch we have three big branches coming up here we've got to supply two vessels up to the head and two vessels around to the arms and so that totals for but we've only got three so on the right hand side be neck and head vessel and the arm vessel are going to come up together and then split up on the left hand side the two vessels are going to come up separate so the one going up to the head is the carotid artery so be the common carotid artery this would be the right common carotid artery and this would be the left common carotid artery and they're going up the neck into the head so that's where you get your carotid pulse and then they're going to split into the internal and external carotid artery the internal is the one that goes to the brain and goes through that carotid canal if you remember from 231 the external supplies all the rest of the things so facing head and central so on the left hand side here is show you the left common carotid artery then this part here is because it's given a site of number of 18a supposed to be the external carotid artery on the left hand side here on the right which ones the internal the internal isn't even shown here it would go through the skull and the so this would be the external left external carotid artery so unique tamarka when you mark them on the sheet for the piratical you need to put out just lor s fine and a or V is fine you need to say if it's artery or vein and you say if it's left or right so that would be left external carotid artery this would be left common carotid artery common because the blood supply is common to the two that it's going to supply so even though those tons of other good stuff going on there we're going to temporarily say that's it for now because it's not a lot of shown in the model and we're going to look at the vessels which you're going to go round to the arms the subclavian artery subclavian because it goes underneath the clavicle so the subclavian artery on the left is here and on the right is here it also has three little branches coming off of it kind of like this and it's curved kind of like this so don't mix up the aortic arch which is coming right out of the heart it's huge compared to the subclavian artery around here so so there it is if I was going to put it I put it kind of conveniently in the middle of its run it's going to change its name here this is the axillary region where the armpit is so this is the axillary artery on the left left axillary artery then the brachial artery over here pretty much where the diathesis of the humerus it's so over here we have right subclavian artery right axillary artery right brachial are it coming down to get the brachial artery is going to divide into radial and ulna and so this person is standing there palm forward anatomical position so then we can assume this is the thumb here so this is the radial artery to the radial pulses on the thumb this is the owner artery and that's about as far as it's going to go in terms of the ones we've got to look at over on this side the person's twisted his hand around like this so if I'm going to mark the radial artery I'll mark them over on this side here because then it's a little easier to see between there but for radial or for a little bit leave the ulnar artery is not reliable enough so down here I feel like I can go down to that as far as the break yellow but you no need to be ridiculous confuse one of the one we're going to have to know and it mentions it here the vertebral artery that's going to come we'll use this one again the very first branch of the subclavian artery is the vertebral artery we don't have to worry about the others but this one what it's going to do it doesn't look like it goes anywhere much what it's going to do is it's going to go back and going to go up along the vertebrae and if you remember from 231 these transfers for Ramon's that are only if I put that the right way up transfers for aimers that are only in the cervical vertebrae those are housing the vertebral artery which is going to go up and then join to the basilar artery and joint to the Circle of Willis and so forth so those are the vertebral arteries and they kind maybe supply the vertebral region a little bit but mostly the supplying the brain and the back of the brain so those are fairly important ones and so even though they're small they're mentioned as possibilities so I think I've got those down we've got these branches here coming up make sure you know the four main ones and then follow the patches down the arm and don't forget they're for people and now we're going to go down to the abdominal region let me go alright so then the thoracic aorta we really can't see so this behind the heart and on the model doesn't isn't there it would supply all of the intercostal muscles between the ribs and so forth but it's not that so completely getting this is the abdominal aorta then and it has various branches and the main ones that we're going to look at in here are all supplying abdominal organs so the first one off here is the celiac trunk it's a little hard to show but what it's going to do it's starting here it's coming out of the aorta it's short and stubby looks rather thin on here it's pretty significant artery but well it is but it looks like it's going to split into three but these three don't look any bigger than don't look any smaller than it seems the hard to imagine how it good so should be thick but there are certain stuffing so the word trunk means an artery that's going to split immediately into a couple of others without really having tributaries of its own it's just going to be a thoroughfare so here's the celiac trunk this part which I know I didn't mention because it's so hard to show you can't really see it but the little place and going back now please let me realize I never actually said the brachiocephalic artery is or brachiocephalic trunk is this little part where the blood is common to the common carotid and the subclavian if you see what I mean because it's impossible to see there's really no way that I could realistically say what's this and have it not seem like I'm Camila orti guards though probably would not ask you that but that's what that is anyway so there it says break here cephalic bar during the first one offer being much and then so getting back to here so celiac chronic means it's good it's going to immediately brunch into others in this case three so we've got the splenic artery going this is meant to be the spleen hepatic artery isn't meant to be the liver so actually the common hepatic artery and then the left gastric artery which is one of the main artery supplying the stomach which isn't shown so it looks like it doesn't really go anywhere but it is going to good stuff so that question sometimes comes up as well in those quizzes or whatever it's which of the three vessels supplied by the celiac trunk so you want to know what the three are and there they are listening then we have well I'll show the renal arteries because those are nice and clear there's a left and a right so we have two kidneys and the renal artery supply the kidneys renal many kidneys that we have a left and a right renal artery these two are the superior mesenteric artery and the inferior mesenteric artery since this one's slightly higher in the body than this one superior mesenteric artery and inferior mesenteric artery they don't look like they're going anywhere they're actually supplying the intestines why they're called mesenteric what a mesentery is here's for example a large intestine it's got this webbing of connective tissue here which partly anchors it but also allows the vessels to supply their blood and then the arteries and then the veins to drain back up so rather than starting here and running out of oxygen by the time you got to here they can just distribute and Richard so the inferior mesenteric artery is basically supplying the large intestine and the superior mesenteric but primarily the small intestine plus a little bit of the large intestine so both both intestines have a mesentery like that and that's why it's called a messenger a little nob on there that's disappear that's the superior mesenteric artery I know it will be hey the problem is all the digestive viscera have been taken out so all these things don't have anywhere to go but so this for example is the inferior mesenteric artery so this okay it doesn't look like it's doing anything is really going to supply most of the color so the inferior mesenteric artery is supplying the large intestine most there are so let's just say the large intestine the superior mesenteric is supplying the small intestine and you might mark those right I could easily yes it's kind of hard to do but I think if I put it right there hopefully it's obvious enough I'm going for the superior territory and not the aorta because it's no there's nowhere else I can really put it so and in the in right the real are going straight to the kid so those are hopefully clear enough so that'd be a nice easy one you just have to remember to put left renal artery if anything so otherwise it's not don't forget nose don't forget Eleanor don't forget a and B not everything has a left and a right and I mean for example superior mesenteric artery doesn't have left and right because there's only one of them not everything has an artery in the bank like abdominal aorta does not have one make them better shop in it there doesn't have a or two artery but so but most things have a left and a right most things happen – so the aorta now come to an end and we're going to go dividing off so this is the iliac region here the ileum is the one of the bones of the pelvis the iliac crest so is the iliac region at least it's being called that for the purposes of this and once again I've got a common iliac artery which is going to divide into a an interior and an exterior iliac artery like the common carotid divided into internal and external carotid so the internal iliac artery is supplying the pelvic region the external iliac artery is going on down to the legs and right about here it's going to divide there's going to be some branches of which we need to know these two here this is the femoral artery or femoral again corresponding to the brachial it's pretty much along the diathesis of the femur here and this is the the deep femoral artery so just a little bit deeper than this one so so there they are the femoral and the deep femoral artery notice we're not worrying about what we're injecting only the ones that are on there so and again we got a few name changes so we've got the we had I guess the common iliac artery then we had the left external iliac artery then we had the left femoral artery this is the popliteal region behind the knee so the popliteal artery and then it's dividing into the anterior and posterior tibial arteries so luckily the anterior tibial artery goes in front of the tibia and the posterior behind this of the some method to their madness and then we almost don't feel we need this one because we didn't have any hand but they put the dorsal pedis artery and perhaps the reason why it's on there is next week when we're testing for the pulse points that's one of the ones actually kind of hard to feel but down on the foot you try to feel where the dorsal pedis artery is kind of faint but you can get it so right down there so those are the arteries except for one important one which is the pulmonary once again pulmonary trunk suggests like celiac trunk that it's going to split without really doing much else other than just splitting so here's an artery coming off and dividing into the left and right pulmonary arteries notice its color it's blue so what if I put one of these on here you'd have to say it was the left pulmonary artery so oh that I'm probably going to trick you with one of those like if you have it you know those Men's Wearhouse commercials where the guy gums on says I guarantee it you know that you know those stain I guarantee much empty it yet mixture of u n– example there's always someone who gets it wrong with this day you know it's like oh don't just go by the color and you've got to remember the pulmonary system is the other way so okay the lower limbs of the mains we'll work our way back up now oh so yeah so this would be the right right pulmonary artery it looks like it's going into there but actually it isn't it this is they're using whatever yeah so if it's in the lungs somewhere here then it's a pulmonary artery if it's blue it's a pulmonary oh okay so then lower limbs they don't really show a whole lot of veins there's none over here at all and over here a lot of them are either just little bumps like I think that's meant to be where the femoral vein is coming in one of these is meant to be the deep femoral vein perhaps that one but they're not really showing them connected and it's up seems a little unfair so there's only one really good one which is showing might require a little explanation the fact that pretty much all these arteries have a vein that has their same name that is their partner Bank but in the limbs it's difficult to get the blood back in event it's pretty easy to shoot it down with the blood pressure in the artery getting it backs of problems so there's extra pathways and one of the extra pathways in the veins from the legs is the great saphenous vein so it's a fairly long Bank because unlike the arteries which have lots and lots of little names the the sort of extra veins are just all called one hair so the great saphenous vein goes all the way from the foot and lower leg all the way up here into the iliac into the external iliac vein so it's a beauty and it's on our list there's also the lesser saphenous vein which isn't even on so and most of those other ones you really can't see good examples of those until we get to the iliac veins and then they look absolutely great and they illustrate the idea that there are partner arteries and veins so here are the external iliac arteries these are the external iliac veins returning here with the X the internal iliac arteries internal iliac veins returning and now the blood supply is common going this way so these are the common iliac veins here so they're exactly matching the arteries of the same name so that would be internal iliac this would be the inch this would be the right internal iliac vein if we wanted to give it its full length so if this was number five right here then it would be the right internal iliac vein and this would be the right internal a contour right next to it oh okay yeah I got to make sure we get more from so then we're moving into the pelvic region which I did abdominal region we've got the left and right renal veins for sure there's a little curiosity which we can't see on here but it was in one of the pathways which is the odd the fact that the go natebain is whether it's ovarian or testicular the right one goes straight into the inferior vena cave and the left one for some bizarre reason goes into the piggy backs into the left renal vein and then into the inferior vena cave so when it was asking for the to progress from the testes to the right hand the left one's going to go via the left renal vein why that's true I don't know but it's true for men and women and it's also true for cats when we used to do the cat dissection you can see it very clearly yeah so somewhere in our distant ancestry that kind of got locked in and never had a reason to change so there it is moving along there for two things we can see so here's the inferior vena cava and very large it is and anybody see the body works anybody who ever see Body Works use it I mean I know veins are bigger than arteries but I was surprised to see I mean the the abdominal aorta is a pretty good size and then the inferior vena cava is just as huge stretched out thing it's like twice the diameter oh so I was just like really huge I thought whoa that is big because it's very hard to you know you're working against gravity to get all of this up relying on the respiratory pump to try to get it through the diaphragm it's just going to pull a lot of blood and so I guess it gets stretched out and I was I was surprised how much bigger it was in that particular person's example but anyway so whereas all the rest of the digestive viscera where's all the superior mesenteric and the inferior mesenteric here and everything well they're all collecting and they're not going to go into the inferior vena cava they're all going to go to the liver all the food we've just eaten and have the absorption from we're going to go to the liver for some kind of purification to make sure that we didn't eat or drink anything too foolish or too large and qualities or whatever so we're going to try to detox what we just ate before that blood is allowed back in the blood system it goes through the brain so and the spleen also because the spleen is where the red blood cells get their comeuppance and so all that iron is going to be brought so all of these vessels from these viscera are going to go through the hepatic portal man so so this is actually the superior mesenteric veins collecting here this is actually the splenic vein coming from the spleen since that must be the gastric vein because it's coming from where the stomach supposedly is so all those things are collecting in and going to the liver via the hepatic portal vein and you know that if I could see the petach portal vein anywhere in there it would be a choice one for me to put on but unfortunately I can't because we really we can sort of see everything heading towards it the next thing we know we're in the liver so I really caught but I can see this going out from the liver all of that blood going back into the inferior vena cava that is the hepatic back now the hepatic portal name which is bringing the blood supply to the liver the used blood from all the digestive is Ronald food and stuff but the hepatic vein man is what's going out of the liver so we just had a hepatic artery and a hepatic vein artery becoming in vain and be going out so that's the hepatic vein it just carries a lot more blood than its regular blood supply because it brought in from all those other organs so that so if that does get marked you've got to mark it as a patek lying on your way then we have the arms and again the would be an ulnar a radial a brachial and all of those that just not shown what is shown is the two extra ones kind of like the great saphenous vein so we've got and again they're they only have one name for their whole length because it sort of extras the best silic and the cephalic may and so no this is on here so the cephalic is this outside one and here's the basilic thing it shows a little bit of the brachial vein it has the same numbers of brachial artery 24 so we can see they go together so how can we remember which is which of these where we can remember that the two bees end up joining together so the brachial and the basilic end up joining together and then the cephalic comes in higher up here so and this little vein going across here which would go across probably not at such an angle but more like that is the median cubital vein right here where blood is up and drawn so that's just put in there too it doesn't show it very clearly and well but it kind of is a so if you know this if this is moving sluggishly we can scoot over there switching lanes on the freeways what's I'm not sure even what that's meant to be to be quite honest I don't know there's a lot of disorientation ok so then as we get up here we're starting to get our partner system again so so here a little bit of the brachial not enough really to make that very fair if I'm going to go for the brachial I probably go for the brake because that's just a little stubborn but it would be the brachial pain is joining up we're in the axillary region now right in the armpit so there's the axillary vein as soon as the cephalic joins in we're right next to the subclavian artery and here's a subclavian vein and on this side we've got just that much of the subclavian vein showing there so so there's a subclavian vein of this vein now here's the one case of one of the probably very few cases where we have what we might consider a partner vein but it doesn't have the same name we have a carotid artery and the jugular vein and why I'm not sure that they ended up with two different names maybe because the neck is kind of important so actually when people say they're going for the jugular although that probably isn't great it's better than going for the carotid because of all the pulse in the carotid which you've lose a lot more blood than if somebody merely stabbed you in the jerk neither would be particularly that sure so I'll go over the jerk carotid yeah what do you think about not wait to use that someday it's gonna happen yes yes the other one is when which I always get on I belong to a writers group people is always saying the blood pulse through his veins I'm like oh no thanks so much comments time in that cousin ok blood pulse to his veins pretty unlikely and let's be less a nutter so that's right so that's the juggler it's actually the internal jugular which is by far the bigger of the two jugglers so this is the right internal jugular vein kind of partnering with the common carotid and here's the left internal jugular vein kind of partnering with the left common carotid then they're going to the subclavian vein and the internal jugular vein going to join up to form the brachiocephalic vein and there should be a break it looks like this one on this side but not really here but actually there is meant to be a left and a right brachiocephalic vein but only if I'm going to put it I would only put the left one because they haven't given us anything to work with there's a model of small show yeah oh she looks like yeah there you go Lizzy baby so but here you can see that yes this is a little bit shorter than that but it definitely makes more of a why here's a superior vena cava and there's the right and left brachiocephalic veins here the internal jugular is coming down and the subclavian veins coming from that one stick so so that kind of a better picture over there it sort of looks weird as to what exactly is going on but this is the superior vena cava going right into the atrium there right into the right atrium left brachiocephalic vein and the right brake you spell again we can just kind of imagine that they should have joined these up a bit sooner but didn't want to cover over all this only so much you can do the same oh so all right how many people see that actually seeing that film but is grateful very very fine okay so that's pretty much except for the pulmonary circulation so if I happened to make number four this little guy you would say it is left pulmonary vein very good is bringing that oxygenated blood back to the heart tricky tricky truck getting in there oh just throw it it's a badge on it hahaha okay okay that is it yeah

  1. Does anyone know of a video like this that explains clearly the lymphatic system? Is there a lymphatic man?

  2. Really enjoyed this video. He explains everything with such patience. I wish my professor would teach like this.

  3. There are THREE branches off the aorta…The first branch is the brachiocephalic(feel free to google it). I wouldnt watch this for study purposes, guys.

  4. I have spent months researching into human anatomy and discovered a great website at Sebs Study Crammer (check it out on google)

  5. There are many components to learning human anatomy. One resource I discovered which succeeds in merging these is the Anatomy Blueprint Pro (check it out on google) without a doubt the most helpful course i've heard of. look at this interesting resource.

  6. Man! I go to Portland Community College, and I wish the professors would take the time to do this! Great video with an amazing professor who doesn't just sit at his desk and say "go to work, learn it yourself!"

  7. Such an excellent teacher!!!! Wow. Really help me understand the pathway. We we on our own in Lab. "Here's the models, go find the vessels". And yes, gotta love Monty Python. Although my hubby fell asleep while watching. Not everyone enjoys a classic comedy

  8. Excellent video!…this helped me soooooo much! Love the details and explanations throughout the video that connect everything together….
