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 |

Asthma is caused by:
| 1. | Inflammation of the bronchi and bronchioles, causing difficulty in breathing |
| 2. | Damage to alveolar walls due to smoking |
| 3. | Accumulation of fluid in the pleural cavity |
| 4. | Swelling of the nasal cavity |

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. |

Due to increasing airborne allergens, people suffering from respiratory disorder manifest wheezing due to
| 1. | Reduction in the secreation of surfactants by pneumocytes |
| 2. | Proliferation of fibrous tissue and damage of alveolar walls |
| 3. | Inflammation of bronchi and bronchioles |
| 4. | Benign growth on mucous lining of alveoli |
