Question

Quizplus · Accepted Answer

Normal, resting exhalation/expiration of air from the lung is a passive process that does not require muscle contraction. It is instead driven by elastic recoil of the lungs and chest wall. Contraction of the exhalatory/expiratory intercostal muscles is only needed during forced exhalation, such as during exercise or coughing.
