Question

The breakdown of alveoli that reduces the surface area for gas exchange leads to a disease called:

• A. Asphyxia
• B. Hypoxia
• C. Anorexia
• D. Emphysema

Answer 1

Answer:

D. Emphysema

Emphysema is a chronic lung disease caused by the breakdown of alveoli, which are tiny air sacs in the lungs In emphysema, the walls of the alveoli break down, causing them to rupture and create one large air pocket instead of many small ones. This reduces the surface area available for the exchange of oxygen and carbon dioxide. The damage is permanent and irreversible, but there are ways to manage the condition.
