Vedclass · Answer

(A) During the process of inspiration (inhalation),the diaphragm muscles contract. This contraction causes the diaphragm to flatten and move downwards,which increases the volume of the thoracic cavity in the antero-posterior axis. This increase in volume leads to a decrease in intrapulmonary pressure,causing air to rush into the lungs from the atmosphere.
