| c. | Inspiratory reserve volume | (iii) | 1-1.1 L |
| d. | Tidal volume | (iv) | 1.1-1.2 L |
| (a) | It includes ERV, TV and IRV |
| (b) | Total volume of air a person can inspire after a normal expiration |
| (c) | The maximum volume of air a person can breathe in after forced expiration |
| (d) | It includes ERV, RV and IRV. |
| (e) | The maximum volume of air a person can breathe out after a forced 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. |
| i. | The approximate ratio of residual volume and total lung capacity is 1 : 5 |
| ii. | Haldane effect describes the dissociation of CO2 from Hb and facilitates its release into alveoli due to oxygenation of Hb |
| iii. | Maximum CO2 is carried in the blood as NaHCO3 |
| iv. | When a plain dweller move to high altitudes (3,500 m or more), he/she will have increase in RBC production and decreased breathing rate |
| v. | Under certain conditions, the P50 value of Hb rises, due to this the affinity of Hb of combining with O2 rises. |
