Arrange the following terms based on their volumes in an ascending order

a. Tidal Volume (TV)


b. Residual Volume (RV)


c. Inspiratory Reserve Volume (IRV)


d. Expiratory Capacity (EC)



Hence, the arrangement of these terms according to their volume in ascending order would be :


Tidal Volume (TV) <Residual Volume (RV) <Expiratory Capacity (EC) <Inspiratory Reserve Volume (IRV) .
