Solution
The correct option is C C
Tidal Volume (TV): Volume of air inspired or expired during a normal respiration. It is approximately 500 ml.
Inspiratory Reserve Volume (IRV): Additional volume of air, a person can inspire by a forcible inspiration. This averages 2500 ml to 3000 ml.
Expiratory Reserve Volume (ERV): Additional volume of air, a person can expire by a forcible expiration. This averages 1000 ml to 1100 ml.
Residual Volume (RV): Volume of air remaining in the lungs even after a forcible expiration. This averages 1100 ml to 1200 ml.
