Answer 2

Answer:

Exhalation is the flow of the breath out of an organism.

It depends oh pressure gradients between the lungs and atmosphere,as well as the muscles in the thoracic cavity.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 comparision to the atmosphere;thus,air rushes out of the airway. There is no contraction of muscles during exhalation ;it is considered a passive process.
