Match the items given in Column I with those in Column II and select the correct option given below:
Column I
- a. Tidal volume
- b. Inspiratory Reserve volume
- c. Expiratory Reserve volume
- d. Residual volume
Column II
- i. 2500 – 3000 mL
- ii. 1100 – 1200 mL
- iii. 500 – 550 mL
- iv. 1000 – 1100 mL
Correct answer: a → iii, b → i, c → iv, d → ii
Explanation
TV ≈ 500 mL, IRV 2500–3000 mL, ERV 1000–1100 mL, RV 1100–1200 mL.
Detailed Solution
Tidal volume is the volume of air inspired or expired during normal respiration; it is approximately 500 mL.
Inspiratory reserve volume is the additional volume of air a person can inspire by a forceful inspiration; it is around 2500–3000 mL.
Expiratory reserve volume is the additional volume of air a person can expire by a forceful expiration; this averages 1000–1100 mL.
Residual volume is the volume of air remaining in the lungs even after forceful expiration; this averages 1100–1200 mL.
Correct match: a-iii, b-i, c-iv, d-ii.
