Which one of the following gives the correct description of a health disorder?

Options

A. Asthma- Inflamniation of pleural membranes of the lung
B. Jaundice - Bilirubin is not produced in the body
C. Emphysema- Alveolar walls are damaged
D. Constipation- Increased frequency of bowel movement

Answer

To solve the question regarding which description correctly identifies a health disorder, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Disorders**: The question presents four health disorders: asthma, jaundice, emphysema, and constipation. We need to evaluate the descriptions associated with each disorder.

2. **Evaluate Asthma**:
- Asthma is characterized as a breathing condition often triggered by allergens.
- The description states that asthma is a condition where the airways tighten due to allergies.
- **Conclusion**: The description is partially correct, but it lacks specificity about the nature of asthma and its triggers. Therefore, this option is incorrect.

3. **Evaluate Jaundice**:
- Jaundice occurs due to a buildup of bilirubin in the blood, which can be caused by liver issues or bile duct obstruction.
- The description states that bilirubin is not produced in the body, which is incorrect since bilirubin is a natural byproduct of the breakdown of red blood cells.
- **Conclusion**: This description is incorrect.

4. **Evaluate Emphysema**:
- Emphysema is a chronic lung condition that causes breathing difficulties due to damage to the alveoli (air sacs in the lungs).
- The description states that the valves of the alveoli are damaged, which aligns with the known pathology of emphysema.
- **Conclusion**: This description is correct.

5. **Evaluate Constipation**:
- Constipation is defined as having fewer than three bowel movements per week, indicating infrequent bowel movements.
- The description states there is an increased frequency of bowel movements, which contradicts the definition of constipation.
- **Conclusion**: This description is incorrect.

6. **Final Answer**: Based on the evaluations, the correct description of a health disorder is associated with **Emphysema**, where the alveolar valves are damaged.
