| 1. | Alveolar walls are damaged |

| I. | Asthma | inflammation of bronchi and bronchioles |
| II. | Emphysema | alveolar walls are damaged due to which respiratory surface is decreased |
| III. | Occupational Respiratory Disorders | fibrosis [proliferation of fibrous tissues] |
| 1. | Emphysema | 2. | Asthma |
| 3. | Tuberculosis | 4. | Common cold |
| 1. | Asthma is characterized by excessive mucus production while emphysema involves the destruction of alveoli. |
