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.
the average amount of residual volume in healthy lungs is 1 litre and generally higher in men.

Residual Volume is the difference between the functional residual capacity , which is amount of air left in the lungs after a natural exhalation , and the expiratory reserve Volume , which is the maximum amount of air in a person can still let out after natural exhalation
