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. On average, a person’s RV is about 1200 ml and doctors can run special tests to find a person’s RV, as it can indicate lung health.
