Vedclass · Answer

(C) Breathing involves the process of filling the lungs with atmospheric air and then emptying them. Breathing in is known as inspiration or inhalation,while breathing out is known as expiration or exhalation.During inspiration,the diaphragm muscles contract,which causes the diaphragm to flatten. This movement increases the volume of the thoracic cavity in the antero-posterior axis,facilitating the entry of air into the lungs.
