Q. No.Each terminal bronchiole gives rise to a cluster of very thin, irregular-walled pouch-like structures called alveoli. Functionally, this structural organisation increases:
| 1. | Rate of diffusion by increasing surface area |
| 2. | Diffusion distance |
| 3. | Air turbulence |
| 4. | Dead space |

Emphysema is characterized by:
| 1. | Excess mucus production blocking bronchioles. |
| 2. | Inflammation of pleural membranes. |
| 3. | Constriction of trachea due to excess fluid accumulation. |
| 4. | Damage to alveolar walls, reducing surface area for gas exchange. |
