The biological term for an air sac is alveolus. The plural is alveoli.
There are millions of air sacs in each of your lungs. Each air sac is made up of tiny hollow bubbles called alveoli, and so there is a very big surface for gases to get into and out of the blood.The inside of each air sac is moist.The gas dissolves in the moisture, then passes through the air sac wall.This is very much like a frog as they use there skin to absorb moiture and turn them into gases for breathing.
