NEET Zoology (general) MCQ Question
Type: MCQ-numerical-Medium-Class 11
If the average residual volume (RV) in the lungs is 1150 mL, what is the functional residual capacity (FRC) if the expiratory reserve volume (ERV) is 1100 mL?
A
2250 mL
B
1100 mL
C
1200 mL
D
225 mL
Correct Answer
Option A
Detailed Explanation
Functional Residual Capacity (FRC) is the volume of air remaining in the lungs after a normal expiration and is the sum of the expiratory reserve volume (ERV) and the residual volume (RV). Thus, FRC = ERV + RV = 1100 mL + 1150 mL = 2250 mL.
