Q. No.The pulmonary function of a person reveals the following values:
a. tidal volume = 500 mL
b. residual volume = 1000 mL
c. inspiratory reserve volume = 2500 mL
d. expiratory reserve volume = 1000 mL
His vital capacity is

Lungs are made up of air-filled sacs, the alveoli. They do not collapse even after forceful expiration, because of
1. Residual Volume (RV)
2. Inspiratory Reserve Volume (IRV)
3. Tidal Volume (TV)
4. Expiratory Reserve Volume (ERV)
| Column I | Column II | ||
| a. | Tidal volume | (i) | 2500-3000 mL |
| b. | Inspiratory Reserve | (ii) | 1100-1200 mL |
| c. | Expiratory Reserve | (iii) | 500-550 mL |
| d. | Residual volume | (iv) | 1000-1100 mL |
| a | b | c | d | |
| 1. | iii | ii | i | iv |
| 2. | iii | i | iv | ii |
| 3. | i | iv | ii | iii |

The given graph shows the pulmonary volumes of a healthy man recorded on spirometer.
Which of the following would be correct?
1. D can be exhaled only after maximum expiratory efforts
2. The value of B will be different for inhalation and exhalation
3. The amount of air remaining in lungs after a normal exhalation is C + D
4. Total lung capacity cannot be calculated from this graph as it includes residual volume
