Which of the following disorders represents decrease in respiratory surface due to damaged alveolar walls?
1. Hypocapnia
2. Bronchitis
3. Asthma
4. Emphysema
Due to increasing air-borne allergens and pollutants, many people in urban areas are suffering from respiratory disorder causing wheezing due to:
1. | reduction in the secretion of surfactants by pneumocytes |
2. | benign growth on mucous lining of nasal cavity |
3. | inflammation of bronchi and bronchioles |
4. | proliferation of fibrous tissues and damage of the alveolar walls |
1. | Inflammation of bronchioles; decreased respiratory surface |
2. | Increased number of bronchioles; increased respiratory surface |
3. | Increased respiratory surface; inflammation of bronchioles |
4. | Decreased respiratory surface; inflammation of bronchioles |
