Total lung capacity is

Options

A. 1200 mL
B. 2400 mL
C. 500 mL
D. 5800 mL

Answer

**Step-by-Step Solution:**

1. **Understanding Total Lung Capacity (TLC)**:
- Total Lung Capacity is defined as the maximum amount of air that the lungs can hold after a maximum inhalation. It includes all the air in the lungs and the respiratory passages.

2. **Components of Total Lung Capacity**:
- Total Lung Capacity (TLC) is the sum of two main components:
- **Vital Capacity (VC)**: The maximum amount of air that can be exhaled after a maximum inhalation.
- **Residual Volume (RV)**: The amount of air that remains in the lungs after a maximum exhalation.

3. **Formula for Total Lung Capacity**:
- The formula to calculate Total Lung Capacity is:
\[ TLC = VC + RV \]

4. **Values of Vital Capacity and Residual Volume**:
- For an average adult, the typical values are:
- Vital Capacity (VC) is approximately 4800 ml.
- Residual Volume (RV) is approximately 1200 ml.

5. **Calculating Total Lung Capacity**:
- Using the average values:
\[ TLC = 4800 \, \text{ml} + 1200 \, \text{ml} = 6000 \, \text{ml} \]
- However, the typical value for Total Lung Capacity is often cited as approximately 5800 ml in various references.

6. **Choosing the Correct Option**:
- Among the options provided (1200 ml, 2400 ml, 500 ml, or 5800 ml), the closest and most accurate value for Total Lung Capacity is **5800 ml**.

**Final Answer**: The correct option for Total Lung Capacity is **5800 ml**.
