NEET Zoology Gas Exchange MCQ Question
Type: MCQ-numerical-Medium-Class 11
If a person has a tidal volume (TV) of 500 mL, an inspiratory reserve volume (IRV) of 2500 mL, and an expiratory reserve volume (ERV) of 1000 mL, what is the functional residual capacity (FRC) if the residual volume (RV) is 1200 mL?
A
2200 mL
B
1700 mL
C
2500 mL
D
3700 mL
Correct Answer
Option A
Detailed Explanation
Functional Residual Capacity (FRC) is the volume of air remaining in the lungs after a normal expiration, calculated as ERV + RV. Therefore, FRC = 1000 mL (ERV) + 1200 mL (RV) = 2200 mL.
