From the following relationships between respiratory

Question:

From the following relationships between 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 ReserveVolume (IRV)

a. (i) Incorrect, (ii) Incorrect, (iii) Incorrect, (iv) Correct

b. (i) Incorrect, (ii) Correct, (iii) Incorrect, (iv) Correct

c. (i) Correct, (ii) Correct, (iii) Incorrect, (iv) Correct
