The physical act of moving air into and out of the lungs is called

Explanation:
Ventilation is the mechanical movement of air into and out of the lungs. It’s the act of breathing in and out, the physical process that brings air to the sites of gas exchange. This differs from respiration, which refers to gas exchange in the lungs and tissues (external and internal respiration) and from perfusion, which is the blood flow needed for that exchange. Oxygenation describes how well blood is loaded with oxygen after air has reached the lungs. So the term that matches the described action of moving air is ventilation.
