The volume of air that remains in the lungs after maximum respiration is __________.

Options

A. 1000 to 1100 ml
B. 1100 to 1200 ml
C. 2000 to 3000 ml
D. 5200 to 5800 ml

Answer

To solve the question regarding the volume of air that remains in the lungs after maximum respiration, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the volume of air that remains in the lungs after maximum respiration. This is a specific term in respiratory physiology.

2. **Identifying the Relevant Term**: The term that describes the volume of air remaining in the lungs after maximum expiration is known as "Residual Volume."

3. **Definition of Residual Volume**: Residual Volume (RV) is the amount of air that remains in the lungs even after a person has exhaled as much air as possible. This volume prevents the lungs from collapsing and ensures that gas exchange can continue even between breaths.

4. **Typical Value of Residual Volume**: The average value of residual volume in a healthy adult is typically between 1100 ml to 1200 ml.

5. **Choosing the Correct Option**: From the given options:
- 1000 to 1100 ml
- 1100 to 1200 ml
- 2000 to 3000 ml
- 2200 to 5800 ml

The correct answer, based on the definition and average value of residual volume, is **1100 to 1200 ml**.

### Final Answer:
The volume of air that remains in the lungs after maximum respiration is **1100 to 1200 ml**.
