Question

name the respiratory volume that is defined as the amount of air moved in, then out, during a single respiratory cycle.

tidal volume (tv)
residual volume (rv)
total lung capacity (tlc)
vital capacity (vc)

Explanation:

Tidal volume (TV) is the volume of air that is inhaled or exhaled in a single respiratory cycle during normal breathing. Residual volume (RV) is the volume of air remaining in the lungs after maximum exhalation. Total lung capacity (TLC) is the total volume of air in the lungs after maximum inhalation. Vital capacity (VC) is the maximum volume of air that can be exhaled after maximum inhalation.
