Question

The solubility of $C{O}_2$ in the blood is

• A. 10-15 times higher than that of $O_2$
• B. 20-25 times higher than that of $O_2$
• C. slightly higher than that of $O_2$
• D. slightly lower than that of $O_2$

Answer 1

Answer: (B)

The solubility of $C{O}_2$ is $20-25$ times higher than that of $O_2$. Therefore, the amount of $C{O}_2$ that can diffuse through the diffusion membrane per unit difference in partial pressure is much higher as compared to that of $O_2$.
