Match the items given in Column I with those in Column II and select the correct option given below:
| Column I | Column II |
| a. Tidal volume | i. 2500 – 3000 mL |
| b. Inspiratory Reserve volume | ii. 1100 – 1200 mL |
| c. Expiratory Reserve volume | iii. 500 – 550 mL |
| d. Residual volume | iv. 1000 – 1100 mL |
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) - a-iii, b-i, c-iv, d-ii
| Column I | Column II |
| a. Tidal volume | iii. 500 – 550 mL |
| b. Inspiratory Reserve volume | i. 2500 – 3000 mL |
| c. Expiratory Reserve volume | iv. 1000 – 1100 mL |
| d. Residual volume | ii. 1100 – 1200 mL |
Tidal volume is volume of air inspired or expired during normal respiration. It is approximately 500 mL.
Inspiratory reserve volume is additional volume of air a person can inspire by a forceful inspiration. It is around 2500 – 3000 mL.
Expiratory reserve volume is additional volume of air a person can be expired by a forceful expiration. This averages 1000 – 1100 mL.
Residual volume is volume of air remaining in lungs even after forceful expiration. This averages 1100 – 1200 mL.
