Vedclass · Answer

(D) Vital Capacity $(VC)$ is defined as the maximum volume of air a person can breathe in after a forced expiration.It includes the Expiratory Reserve Volume $(ERV)$,Tidal Volume $(TV)$,and Inspiratory Reserve Volume $(IRV)$.Mathematically,$VC = ERV + TV + IRV$.Since Total Lung Capacity $(TLC)$ is the sum of all lung volumes including Residual Volume $(RV)$,i.e.,$TLC = IRV + TV + ERV + RV$,we can derive that $VC = TLC - RV$.
