Reduction in respiratory surface of lungs due to breakdown of partition in the alveoli is known as

Options

A. Asphyxia
B. Bronchitis
C. Asthma
D. Emphysema

Answer

**Step-by-Step Text Solution:**

1. **Identify the Condition**: The question describes a reduction in the respiratory surface of the lungs due to the breakdown of partitions in the alveoli. This condition is characterized by the destruction of alveolar walls.

2. **Understanding Alveoli**: Alveoli are tiny air sacs in the lungs where gas exchange occurs. They provide a large surface area for the diffusion of oxygen and carbon dioxide. When the partitions (walls) between the alveoli break down, it reduces this surface area.

3. **Name the Disease**: The condition described is known as **Emphysema**. In emphysema, the alveoli lose their elasticity and surface area, leading to difficulty in breathing and impaired gas exchange.

4. **Effects of Emphysema**: As a result of the destruction of alveoli, there is defective air diffusion. This leads to an increase in carbon dioxide (CO2) levels and a decrease in oxygen (O2) levels in the body, which can cause symptoms such as shortness of breath.

5. **Conclusion**: Therefore, the answer to the question is that the reduction in the respiratory surface of the lungs due to the breakdown of partitions in the alveoli is known as **Emphysema**.
