Question

Listed below are four respiratory capacities (i-iv) and four jumbled respiratory volumes of a normal human adult.

Respiratory volumes and capacities	Volume of air
(i) Residual volume	2500 mL
(ii) Vital capacity	3500 mL
(iii) Inspiratory reserve volume	1200 mL
(iv) Inspiratory capacity	4500 mL

Which one of the following is the correct matching of two capacities and volumes?

• A. (ii) 2500 mL, (iii) 4500 mL
• B. (iii) 1200 mL, (iv) 2500 mL
• C. (iv)3500mL, (i) 1200 mL
• D. (i) 4500 mL; (ii) 3500 mL

Answer 1

The correct option is C (iv)3500mL, (i) 1200 mL

Respiratory volumes and capacities Volume of air

Residual volume 1200 mL Vital capacity 4500 mL

Inspiratory reserve volume 2500 mL Inspiratory capacity 3500 mL.
