Question

Identify the correct and incorrect match about respiratory volume and capacities and mark the correct answer.

i. Inspiratory capacity (IC) = Tidal Volume + Residual Volume
ii. Vital Capacity (VC) = Tidal Volume (TV) + Inspiratory Reserve Volume (IRV) + Expiratory Reserve Volume (ERV).
iii. Residual Volume (RV) = Vital Capacity (VC) - Inspiratory Reserve Volume (IRV)
iv. Tidal Volume (TV) = Inspiratory Capacity (IC) - Inspiratory Reserve Volume (IRV)

TestHub · Accepted Answer

Inspiratory capacity is the amount of air inhaled during normal breathing and also during forceful breathing. Thus $I C = T V + I R V$

Residual volume is the amount of air left in the lungs after forceful breathing.

Thus $R V = F R C - E R V$

Tidal volume is amount of air inhaled or exhaled during normal breathing

$T V = I C - I R V (I C i s T V + I R V)$

Vital capacity includes all the volumes except tidal volume.
