All right, now here we are talking about the path of blood through the pulmonary circuit, and it's called pulmonary because blood goes from the heart to the lungs and then back.
00:43
So let's look at the heart.
00:45
As you know, the heart is split up in four chambers, atriot top, ventricles on the bottom.
01:00
Okay, and you have a blood vessel here, venekeva, which gets blood from body, and this here takes blood to the body.
01:30
Okay, now this side of the heart is the right side of the heart.
01:37
Now, you may think, well, it looks like it's on the left side to me, but it's kind of like when we're looking, at a specimen in a dissection tray.
01:47
Okay, if a specimen, you're looking at one lying a dissection tray, this would be the right side of the heart.
01:56
Okay, so now blood from the body has used up all the oxygen.
02:01
So this is deoxygenated blood.
02:09
And that deoxygenated blood is going to go here into the right side of the heart first.
02:18
Okay, and then that blood is going to go through another blood vessel.
02:30
We'll cross it back right here into the lungs.
02:38
And in the lungs, as we know, there it's going to pick up oxygen.
02:46
Okay...
