What is the percentage of `O_(2)` transported in
dissolved form through the plasma?

Options

A. About 7%
B. About 3%
C. About 20-25%
D. About 15%

Answer

To determine the percentage of oxygen transported in dissolved form through the plasma, we can follow these steps:

### Step-by-Step Solution

1. **Understand the Transport of Oxygen**: Oxygen is transported in the blood in two main ways:
- Bound to hemoglobin in red blood cells (RBCs).
- Dissolved in the plasma.

2. **Identify the Percentage of Oxygen Transported**:
- It is known that approximately 97% of oxygen is transported bound to hemoglobin in RBCs.
- The remaining percentage of oxygen is transported in a dissolved state through the plasma.

3. **Calculate the Percentage of Dissolved Oxygen**:
- Since 97% of oxygen is carried by hemoglobin, the percentage of oxygen that is dissolved in plasma can be calculated as:
\[ 100\% - 97\% = 3\% \]

4. **Select the Correct Answer**:
- Based on the calculation, the percentage of oxygen transported in dissolved form through the plasma is **3%**.

### Final Answer
The percentage of `O2` transported in dissolved form through the plasma is **3%**.
