Inspiratory Capacity (IC) = Tidal Volume + Residual Volume
Incorrect, Incorrect, Correct, Correct,

Vital Capacity (VC) = Tidal Volume (TV) + Inspiratory Reserve Volume (IRV) + Expiratory Reserve Volume (ERV).
Incorrect, Correct, Correct, Incorrect,

Residual Volume

Vital Capacity (VC) -Inspiratory Reserve Volume (IRV)
Incorrect, Incorrect, Incorrect, Correct,

Tidal Volume (TV)

Inspiratory Capacity (IC) -Inspiratory Reserve Volume (IRV) Correct Correct Correct Incorrect

Text Solution

Verified by Experts

The correct answer is:

NOT AVAILABLE

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