Question

Match the Column-I with Column-II and select the correct option.
Column-I Column-II
A. Tidal volume (i) 2500–3000 ml
B. Inspiratory reserve volume (ii) 1000 ml
C. Residual volume (iii) 4500 ml
D. Vital capacity (iv) 500 ml

• A. A-iii, B-iv, C-i, D-ii
• B. A-ii, B-iii, C-iv, D-i
• C. A-iv, B-i, C-ii, D-iii
• D. A-iv, B-ii, C-iii, D-i

Hint:

Vital capacity equals tidal volume + inspiratory reserve volume + expiratory reserve volume.

Answer 1

The Correct Option is C

Step 1: Understanding respiratory volumes.
Different lung volumes represent the amount of air inhaled or exhaled during breathing and forced respiration.

Step 2: Matching each term.
Tidal volume is the normal air inhaled or exhaled during quiet breathing, which is about 500 ml.
Inspiratory reserve volume is the additional air inhaled forcibly, about 2500–3000 ml.
Residual volume is the air remaining in lungs after forced expiration, about 1000 ml.
Vital capacity is the maximum air exhaled after maximum inhalation, about 4500 ml.

Step 3: Conclusion.
Thus, the correct matching is A-iv, B-i, C-ii, D-iii.
