A) Inspiratory Reserve Volume (IRV) + Expiratory Reserve Volume (ERV) + Tidal Volume (TV) + Residual Volume (RV)
B) IRV + RV + ERV
C) IRV + TV + ERV
D) TV + RV + ERV
Correct Answer: C
Solution :
The maximum amount of air which can be breathed out through forceful expiration after a forceful inspiration is called Vital Capacity (VC). It is sum total of Tidal Volume (TV), Inspiratory Reserve Volume (IRV) and Expiratory Reserve Volume (ERV). The value for vital capacity is about 3.4 - 4.8 litres.You need to login to perform this action.
