Residual volume is

A

Lesser than tidal volume

B

Greater than inspiratory volume

C

Greater than vital capacity

D

Greater than tidal volume

Text Solution

Verified by Experts

The correct Answer is:
D
the residual volume is that part of the air in the lung which cannot be exhaled , it represents the remaining volume of lung when forced exhalation of the lung has occurred.
