Question

importance of residual volume of air in cell​

Answer 1

Answer:

Residual volume is the amount of gas remaining in the lungs at the end of a maximal exhalation. Residual Volume is important because it prevents the lungs from collapsing. Even after we have expelled as much air as possible (expiratory reserve volume) gaseous exchange is still occurring by residual volume in the lungs.

Answer 2

Answer:

The residual volume functions to keep the alveoli open even after maximum expiration.
