Question

Why isn't the sum of inspiratory reserve volume (IRV) and expiratory reserve volume (ERV) equal to the slow vital capacity (SVC)?

Answer 1

The sum of IRV & GRV is not equal to slow . vital capacity because it also includes the Tidal volume at the resting state volume (lt.) JRV slow vital capacity Porced vital capacity Tidal volume ERU. Residual volum → Time(s)

slow vital capacity is the maximum voto volume of are than can be exhaled slowly after stora maximum inhalation & Ier case of airway dostruction, slow intal capacity is the larger than forced vital capacity indicating Air trapping

Felt great to answer. Good luck!
