From the following relationship between respiration volumes and capacities, mark the correct option.
(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) Correct

C

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

D

Text Solution

Verified by Experts

The correct Answer is:
b
(i) Inspiratory Capacity (IC) = Tidal Volume + Inspiratory Reserve Volume (TV + IRV)
(ii) Vital Capacity (VC) Tidal Volume +.lnspiratory Reserve Volume + Expiratory Reserve Volume. (TV+ ERV+ IRV)
(iii) Residual Volume (RV) Volume of air remaining in the lungs after a forcible expiration.
(iv) Tidal Volume (TV) Volume of air inspired or expired during a normal respiration.
