The Total Lung Capacity Equals

Question

The total lung capacity equals
A)TV + IRV + ERV + RV
B)IRV + ERV + RV + MV
C)TV + IRV
D)FRC + ERV + RV
E)TV + ERV + IRV

Accepted Answer

Total lung capacity is the sum of all the four lung volumes, i.e., tidal volume (TV), inspiratory reserve volume (IRV), expiratory reserve volume (ERV), and residual volume (RV). Therefore, option A is the correct choice.
