Question
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 |
a b c d iii ii i iv a b c d iii i iv ii a b c d iv iii ii i a b c d i iv ii iii
Solution
B.
| a | b | c | d |
| iii | i | iv | ii |
- Tidal volume is the volume of air inspired or expired during normal respiration. It is approximately 500 mL.
- Inspiratory reserve volume is an 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 be expired by a forceful expiration. This averages 1000 – 1100 mL.
- Residual volume is the volume of air remaining in lungs even after forceful expiration. This averages 1100 – 1200 mL.
