Which term describes the amount of air moved in and out in each breath?

Explanation:
Tidal volume is the amount of air moved in and out with each normal breath. In an average adult it’s about 500 mL per breath and can vary with body size and activity. This differs from residual volume, which is the air left in the lungs after a full exhale; total lung capacity, the total air the lungs can hold; and vital capacity, the maximum air you can exhale after a deep inhale.
