NEET Zoology Gas Exchange MCQ Question
Type: MCQ-numerical-Easy-Class 11
If a person has a tidal volume (TV) of 500 mL and an expiratory reserve volume (ERV) of 1000 mL, what is their functional residual capacity (FRC) if their residual volume (RV) is 1100 mL?
A
2100 mL
B
1600 mL
C
2600 mL
D
2200 mL
Correct Answer
Option A
Detailed Explanation
Functional Residual Capacity (FRC) is the volume of air remaining in the lungs after normal expiration and is calculated as the sum of Expiratory Reserve Volume (ERV) and Residual Volume (RV). Given ERV = 1000 mL and RV = 1100 mL, FRC = ERV + RV = 1000 mL + 1100 mL = 2100 mL.
