Question

Define : inhalation and exhalation and in these processes we explain where the diaphragm goes

Answer 1

Answer:

• Inhalation: During the process of inhalation, the lung volume expands as a result of the contraction of the diaphragm which results in a decrease in lung pressure in comparison to the atmosphere; thus, air rushes in the airway.

• Exhalation: The process of exhalation occurs due to an elastic recoil of the lung tissue which causes a decrease in volume, resulting in increased pressure in comparison to the atmosphere; thus, air rushes out of the airway.
