STANDARD Zoology Respiratory Volumes and Capacities Multiple Correct Question

Type: Multiple Correct-conceptual-Medium

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)

A

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

B

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

C

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

D

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

Correct Answer

Option B

Detailed Explanation

Inspiratory capacity IC = Tidal Volume + inspiratory reserve volume. Vital Capacity (VC) = Tidal Volume (TV) + Inspiratory Reserve Volume (IRV) + Expiratory Reserve Volume (ERV). Residual Volume RV = ERV + RV. Tidal Volume (TV) = Inspiratory Capacity IC – Inspiratory Reserve Volume (IRV).
