Question

Quizplus · Accepted Answer

In normal exhalation, the relaxation of the diaphragm and intercostal muscles is a passive process, as it doesn't require any additional effort or energy expenditure from the person. This relaxation causes the chest to contract, which creates positive pressure, allowing air to move out of the lungs. Inspiration, on the other hand, is an active process that requires active contraction of the diaphragm and intercostal muscles to expand the chest and create negative pressure for air to move into the lungs. Therefore, option C) is the correct choice.
