Identify the incorrect match about lung volumes.

Options

A. TV-500 ml
B. IRV-3000 ml
C. RV-2000 ml
D. ERV- 1100 ml

Answer

To identify the incorrect match about lung volumes, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understand Tidal Volume (TV)**:
- Tidal Volume (TV) is the volume of air displaced during normal inhalation and exhalation without any extra effort.
- The typical value for TV is around **500 ml**.
- **Match**: Option 1 (TV = 500 ml) is **correct**.

2. **Understand Inspiratory Reserve Volume (IRV)**:
- Inspiratory Reserve Volume (IRV) is the amount of air that can be inhaled after a normal inhalation.
- The typical value for IRV is approximately **2500 to 3000 ml**.
- **Match**: Option 2 (IRV = 3000 ml) is **correct**.

3. **Understand Residual Volume (RV)**:
- Residual Volume (RV) is the amount of air remaining in the lungs after a forced expiration.
- The typical value for RV is around **1100 to 1200 ml**.
- **Match**: Option 3 (RV = 2000 ml) is **incorrect** because it exceeds the normal range.

4. **Understand Expiratory Reserve Volume (ERV)**:
- Expiratory Reserve Volume (ERV) is the amount of air that can be forcibly exhaled after the end of a normal expiration.
- The typical value for ERV is about **1100 to 1200 ml**.
- **Match**: Option 4 (ERV = 1100 ml) is **correct**.

### Conclusion:
The incorrect match about lung volumes is **Option 3: RV = 2000 ml**, as the actual value should be around **1100 to 1200 ml**.
