Lungs are made up of air-filled sacs, the alveoli. They do not collapse even after forceful expiration, because of:
1. Inspiratory Reserve Volume
2. Tidal Volume
3. Expiratory Reserve Volume
4. Residual Volume

Hints
Which of the following statements correctly distinguishes between functional residual capacity (FRC) and residual volume (RV)?
| 1. | FRC is the volume of air remaining in the lungs after a normal expiration, while RV is the volume of air remaining after a forced expiration. |
| 2. | FRC is the volume of air inhaled during a normal inspiration, while RV is the volume of air exhaled during a normal expiration. |
| 3. | FRC is the total lung capacity minus tidal volume, while RV is the total lung capacity minus vital capacity. |
| 4. | FRC is the volume of air that can be exhaled after a normal expiration, while RV is the volume of air that can be inhaled after a normal inspiration. |

| Assertion (A): | The value of tidal volume in a healthy human is about 6000-8000 mL/min. |
| Reason (R): | The volume of air remaining in the lungs even after forcible expiration is 1100-1200 mL. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | Both (A) and (R) are false. |
