The air sac must have thin walls so that air passes easily through it.
Hyper inflation of air sacs with destruction of alveolar walls.
Blood contains more oxygen than air sacs. Oxygen from inhaled air diffuses across the walls of the air sacs into the bloodstream, where it binds to hemoglobin in red blood cells for transport to tissues throughout the body.
The tiny air sacs are called alveoli. Oxygen from the air enters the bloodstream through the walls of the alveoli, while carbon dioxide from the bloodstream is released into the air sacs to be exhaled.
