Question

Quizplus · Accepted Answer

During exhalation, the thoracic cavity decreases in size as the diaphragm and intercostal muscles relax, resulting in the expulsion of air from the lungs.

Answer: D
 Exhalation is an active process only when a person is doing physical activity or exercising. During rest, exhalation is a passive process.

The other options are incorrect:
A) Inhalation is an active process that involves the contraction of the diaphragm and intercostal muscles, not a passive process. 
B) Inhalation involves the contraction of the diaphragm, not relaxation. 
E) Inhalation results in a decrease in intrapleural pressure, not an increase.
