If it only takes 4 minutes without oxygen to cause brain damage, how can they stay underwater for 4+ minuets and not hurt themselves.
In: Biology
As they dive deeper, the increase in pressure on the body actually makes the lungs shrink, but also pushes the oxygen into the blood stream. So there’s some actually complex physics going on.
“Diffusion is the movement of gas molecules from a region of higher concentration to a region of lower concentration until they are equal. This means that the deeper you go, the more oxygen will dissolve into your blood. Then, as you ascend, the volume of air inside your lungs increases, oxygen comes out of the blood, back into your lungs.”
