Question

how is the mammalian lung adapted for rapid gaseous exchange?

seremi amune · Accepted Answer

large network of capillaries surrounds a lot of alveoli to provide large surface area
capillaries and alveoli are each 1 cell thick so short diffusion distance
constant blood circulation and breathing maintains concentration gradients
