WebDuring quiet breathing, the diaphragm and external intercostals must contract. A deep breath, called diaphragmatic breathing, requires the diaphragm to contract. As the diaphragm relaxes, air passively leaves the lungs. A shallow breath, called costal breathing, requires contraction of the intercostal muscles. WebWhen 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. The procedure used to directly examine the trachea and bronchial tree is called bronchoscopy.
