If a person has an expiratory reserve volume (ERV) of 1000 mL and a residual volume (RV) of 1200 mL, what is the functional residual capacity (FRC) of this individual?
A
2200 mL
B
1200 mL
C

D
2000 mL
Correct Answer
Option A
Detailed Explanation
Functional Residual Capacity (FRC) is the volume of air remaining in the lungs after a normal expiration, which includes the expiratory reserve volume (ERV) and the residual volume (RV). Thus, FRC = ERV + RV = 1000 mL + 1200 mL = 2200 mL.
