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.

A deflated sac typically refers to the collapse or reduction in size of a membrane or structure that is usually filled with air or fluid, causing it to lose its usual shape or function. This can happen in various biological contexts, such as deflated alveoli in the lungs or a deflated amniotic sac during childbirth.
A sac typically contains fluid or air and serves various functions depending on its context. In biological terms, sacs can hold substances like blood, bile, or other bodily fluids, such as in the case of the amniotic sac during pregnancy. In a more general sense, a sac can refer to any pouch-like structure that stores or encases materials, such as a bag or pouch.
