Question

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

Respiratory capacities	Respiratory volumes
(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) 3500 mL, (i) 1200 mL
• D. (i) 4500 mL, (ii) 3500 mL

Answer 1

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

Following are the correct values of the given respiratory volumes:

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