Diaphragm and external intercostal muscles
WebDuring EXPIRATION, the intra-alveolar pressure is greater than atmospheric pressure. When the diaphragm contracts, the intra-alveolar pressure DECREASES. As the intercostal muscles relax and the thoracic cavity becomes smaller, the intra-alveolar pressure INCREASES. Most of the inspired air eventually ends up in the. alveoli.
