Vedclass · Answer

(D) The breathing process, or pulmonary ventilation, involves the movement of air into and out of the lungs. This process is primarily driven by changes in the volume of the thoracic cavity. The $2$ main structures responsible for creating these pressure gradients are the $intercostal muscles$ (located between the ribs) and the $diaphragm$ (a dome-shaped muscle at the base of the thoracic cavity). Contraction and relaxation of these muscles alter the thoracic volume, which in turn changes the intrapulmonary pressure, allowing air to flow in or out.
