Weba) Explain normal physiological process of gas exchange ( A&P review) Diaphragm contracts downward causing negative pressure in the lungs. This allows air to rush into the lungs. Diaphragm relaxes back into a dome-shaped position which allows the high pressure that has built-up in the lungs to be forced out with exhalation. WebBecause there are so many alveoli (~300 million per lung) within each alveolar sac and so many sacs at the end of each alveolar duct, the lungs have a sponge-like consistency. …
