Question

what disease associated with smoking is characterized by overexpansion and destruction of alveoli? a asthma b empyema c bronchiectasis d emphysema

Explanation:

To solve this, we analyze each option:

• Option A (asthma): It involves airway inflammation and constriction, not alveolar overexpansion/destruction.
• Option B (empyema): It is a collection of pus in the pleural space, unrelated to alveolar changes from smoking.
• Option C (bronchiectasis): It is the permanent dilation of bronchi, not focused on alveoli.
• Option D (emphysema): This disease, often caused by smoking, is characterized by the overexpansion and destruction of alveoli, leading to reduced gas exchange.

Answer:

D. emphysema
