Type: MCQ-numerical-Medium-Class 11
If the residual volume (RV) in the lungs is 1200 mL and the expiratory reserve volume (ERV) is 1100 mL, what is the functional residual capacity (FRC)?
A
2300 mL
B
1100 mL
C
1200 mL
D
2400 mL
Correct Answer
Option A
Detailed Explanation
Functional Residual Capacity (FRC) is the volume of air remaining in the lungs after a normal expiration. It is the sum of the Expiratory Reserve Volume (ERV) and the Residual Volume (RV). Given ERV = 1100 mL and RV = 1200 mL, FRC = 1100 mL + 1200 mL = 2300 mL.
