Inspiration

Vedclass · Answer

(C) The process of breathing involves two stages: Inspiration and Expiration.$1$. Inspiration (Inhalation) occurs when the intra-pulmonary pressure is less than the atmospheric pressure.$2$. This pressure gradient is created by an increase in the pulmonary volume (thoracic cavity volume),which is primarily achieved by the contraction of the diaphragm and external intercostal muscles.$3$. Because the pressure inside the lungs is lower than the outside atmospheric pressure,air rushes into the lungs.$4$. Therefore,the described mechanism corresponds to Inspiration.

An increase in pulmonary volume decreases the intra-pulmonary pressure to less than the atmospheric pressure,which forces the air from outside to move into the lungs. This process is known as:
