Question

this stage of ventilation requires alveolar pressure to exceed atmospheric pressure. broncho constriction rest inspiration expiration

Explanation:

During expiration, the diaphragm relaxes, the thoracic cavity volume decreases, and alveolar pressure becomes greater than atmospheric pressure, forcing air out of the lungs. Bronchoconstriction is narrowing of airways, rest is a state, and during inspiration alveolar pressure is less than atmospheric pressure.

Answer:

expiration
