Question

Match the items given in column I with those in column II and select the correct options given below:

	Column I		Column II
a.	Tidal volume	1	2500-3000 mL
b.	Inspiratory Reserve volume	2	1100-1200 mL
c.	Expiratory Reserve volume	3	500-550 mL
d.	Residual volume	4	1000-1100 mL

• A. $a-1,b-4,c-2,d-3$
• B. $a-3,b-2,c-1,d-4$
• C. $a-4,b-3,c-2,d-1$
• D. $a-3,b-1,c-4,d-2$

Answer 1

The correct option is D $a-3,b-1,c-4,d-2$

a) Tidal volume is the volume of air displaced between normal inspiration and expiration without an extra effort. In a healthy human, it is approximately 500-550 mL.

b) Inspiratory reserve volume (IRV) is the maximal amount of air that can be inhaled into the lungs by after normal inspiration. In a healthy human, it is approximately 2500-3000 mL.

c) Expiratory reserve volume (ERV) is the maximal amount of air that can be expelled out from the lungs after normal expiration. In a healthy human, it is approximately 1000-1100 mL.

d) Residual volume (RV) is the volume of air that remains in the lungs after the most forcible expiration. In a healthy human, it is approximately 1100-1200 mL.

Thus, the correct answer is option D.
