Breakdown of alveoli of lungs resulting in the reducing surface area for gas exchange is known as

Options

A. Emphysema
B. Sneezing
C. Pneumonia
D. Tuberculosis.

Answer

**Step-by-Step Solution:**

1. **Understanding the Alveoli**: The alveoli are tiny air sacs in the lungs where gas exchange occurs. They are crucial for the exchange of oxygen and carbon dioxide during breathing.

2. **Identifying the Condition**: The question refers to a condition where the walls of the alveoli are damaged or destroyed. This damage leads to a reduction in the surface area available for gas exchange.

3. **Consequences of Alveolar Breakdown**: When the surface area for gas exchange is reduced, it results in symptoms such as shortness of breath, coughing, and wheezing. In severe cases, it can lead to decreased oxygen intake, causing headaches and impaired mental ability.

4. **Naming the Condition**: The medical term for the breakdown of alveoli resulting in reduced surface area for gas exchange is known as "emphysema."

5. **Final Answer**: Therefore, the breakdown of alveoli of lungs resulting in the reducing surface area for gas exchange is known as emphysema.
