Which of these structures have the highest level of oxygenated blood in the mammalian circulatory system? the superior vina cava, the pulmonary vein, the right ventricle, the pulmonary artery, or the right atrium.
00:15
So we have some chambers of the heart, and we also have some major blood vessels here.
00:20
So the heart has four chambers.
00:25
They're kind of split like this.
00:28
So this is the left -hand side, and this is the right.
00:31
At the top we have the atria, at the bottom we have the ventricles.
00:39
So oxygenated blood.
00:41
Well, blood is oxygenated at the lungs.
00:45
So our answer is going to be, whichever structure has most recently been at the lungs.
00:54
So oxygenated at the lungs.
01:01
So if we go from the lungs, where do we go after that? so we have the lungs.
01:06
Well, we take a vessel from the lungs to the left atrium...
