Question

What is meant by residual volume of the air in the lungs?

Answer 1

Answer:

Residual volume (RV) is the amount of air that remains in a person’s lungs after maximum exhalation. In other words, this is the volume of air that we can’t possibly get out of our lungs, meaning that the lungs are never completely empty of air. Otherwise, they would collapse as the tissue sticks together.

Answer 2

Answer:

volume of air still remaining in the lungs after the most forcible expiration possible and amounting usually to 60 to 100 cubic inches (980 to 1640 cubic centimeters) — called also residual air as compare supplemental air.
