The solubility of oxygen is

Options

A. 20 - 25 times higher than carbon dioxide
B. 20 - 25 times lower than carbon dioxide
C. 10 - 15 times higher than carbon dioxide
D. 10 - 15 times lower than carbon dioxide

Answer

To solve the question regarding the solubility of oxygen, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Gas Solubility**:
- Solubility of gases in liquids (like blood) is influenced by the partial pressure of the gas and its inherent solubility in that liquid.

2. **Comparing Oxygen and Carbon Dioxide**:
- It is known that carbon dioxide (CO2) has a much higher solubility in blood compared to oxygen (O2). Specifically, CO2 is 20 to 25 times more soluble than O2.

3. **Implications of Solubility**:
- This means that for every unit of partial pressure difference, carbon dioxide will diffuse through the pulmonary capillary membrane significantly more than oxygen.

4. **Conclusion**:
- Therefore, we can conclude that the solubility of oxygen is relatively low compared to carbon dioxide. The correct answer to the question about the solubility of oxygen is that it is much lower than that of carbon dioxide.

### Final Answer:
The solubility of oxygen is significantly lower than that of carbon dioxide, specifically 20 to 25 times lower.
