Vedclass · Answer

(C) The process of breathing involves the movement of air into and out of the lungs,which is primarily driven by changes in the volume of the thoracic cavity.These volume changes are created by the contraction and relaxation of the diaphragm and the external and internal intercostal muscles associated with the ribs.When the diaphragm and external intercostal muscles contract,the thoracic volume increases,leading to inspiration.When these muscles relax,the thoracic volume decreases,leading to expiration.
