State the volume of air remaining in the lungs after normal breathing.

Asked by Pragya Singh | 1 year ago |  73

##### Solution :-

The volume of air remaining within the lungs after a traditional expiration is understood as functional residual capacity (FRC). It comprises expiratory reserve volume (ERV) and residual volume (RV). ERV is the maximum volume of air that will be exhaled after a traditional expiration. It's about 1000 ml to 1500 ml. RV is the volume of air remaining within the lungs after maximum expiration. It's about 1100 mL to 1500 ml.

Hence,

FRC = ERV + RV

$$≅ 1500 + 1500$$

$$≅ 3000\; mL$$

Thus, the functional residual capacity of the lungs in human beings is nearly 2500 ml to 3000 ml
