Act or process of inhaling and exhaling?

Explanation:
Ventilation is the act of moving air in and out of the lungs, driven by pressure changes created by the diaphragm and respiratory muscles. This mechanical process allows fresh air with oxygen to reach the alveoli and carbon dioxide to be expelled. It’s distinct from perfusion, which is the blood flow to the alveolar capillaries; metabolism, the cellular use of oxygen and production of CO2; and osmosis, the movement of water across membranes. So the act or process of inhaling and exhaling is ventilation.
