00:01
So this problem gives us a diagram and asks us to label blood flow starting with the right ventricle, as well as labeling the structures in which the blood is flowing.
00:15
And just as a quick reminder, when we're looking at anatomical structures, the orientation of the structure is always going to be, if like left and right will be if you imagine that you yourself, own these organs, your left and your right.
00:37
So anything from here over is going to be left, and anything from here over is going to be right.
00:50
All right.
00:52
So let's go ahead and just get started with this problem.
00:56
So our first job is to identify the right, ventricle.
01:01
And we know that it's going to be on the right side in the lower portion of the heart.
01:06
So we'll just draw it there.
01:09
And this will be k.
01:12
So right ventricle.
01:16
The blood is then going to be pumped through to the pulmonary artery.
01:24
So it'll be coming up out of the heart and on its way over.
01:31
To the lungs.
01:34
And in this diagram, we will label this around here for option two.
01:41
And remember again that the body is symmetric.
01:45
And so this problem has asked us to label both sides of this structure.
01:53
So on the left hand side of the body, we'll have c is the pulmonary artery.
02:01
And then the same structure will be labeled on the right side, which will be o.
02:15
All right.
02:17
Next, the blood is going to be flowing into the capillaries of the lungs.
02:24
So both of these are your lungs, left and right sides.
02:29
We will just label these quickly now on our chart.
02:35
The capillaries of the lung here are going to be options d and n.
02:44
I'm just going to call them lungs, but remember these are capillary beds.
02:48
So when you write out your answer, write out capillaries of the lung.
02:52
All right.
02:53
Now the blood is on its way back to the heart.
02:59
So we will draw that.
03:01
They're exiting the capillary bed.
03:03
This is going to be via the pulmonary vein.
03:08
So we'll draw little arrows right now, so we won't spoil the surprise of where this blood is going to go.
03:16
But we will label these structures along the way.
03:21
So this is going to be option number four for both of these guys.
03:27
And like we said, this structure is the pulmonary vein.
03:31
So that's going to be option e and also option m, pulmonary vein.
03:45
All right.
03:46
Now the blood is going to be flowing into the left side of the heart into the atrium.
03:54
So it'll be going up here and converging there.
04:00
And this will be spot number five.
04:04
Once again, we're just going to label that.
04:07
This is going to be the left atrium...
