During expiration, the diaphragm and intercostal muscles relax, causing the thoracic cavity to decrease in volume. This reduction in volume increases the pressure within the lungs, forcing air out of the respiratory tract. The elastic recoil of lung tissue also aids in pushing air out, while the abdominal muscles may assist in expelling air more forcefully during active expiration. Overall, expiration is primarily a passive process during quiet breathing but can become active during vigorous activities.
