Atmospheric pressure is mm of Hg.
Lowering the diaphragm and expanding the rib cage the air pressure inside the lungs and forces air into/out of the lungs.
the air flows down the bronchioles to the alveolar duct to the alveolar sac to the which is surrounded by pulmonary capillaries where teh actual gas exchange takes place.
during inspiration, the rib cage muscles and the diaphragm..
