They also help remove carbon dioxide a waste gas that can be toxic to the body. When you we breathe air passes through the nose and mouth into the windpipe. The air then travels to the lungs air sacs, these sacs are called alveoli. Small blood vessels called capillaries run through the walls of the alveoli; when air reaches the alveoli, the oxygen in the air passes through the air sac walls into the blood capillaries. At the same time, CO2 moves from the capillaries into the alveoli where gas exchange takes place. The alveoli must remain open and filled in order for this process to work right; surfactant, a liquid that coats the inside of the lungs, helps the alveoli stay open.
