Question

The factor, which does not affect the rate of alveolar diffusion is

• A. Solubility of gases
• B. Thickness of the membranes
• C. Pressure gradient
• D. Concentration gradient
• E. Reactivity of the gases

Answer 1

The correct option is E Reactivity of the gases

The solubility of the gases in blood, the concentration gradient of gases, which is the same as the pressure gradient, as well as the thickness of the membranes involved in diffusion, are some important factors that can affect the rate of diffusion.
Whereas, the reactivity of the gases does not affect the rate of alveolar diffusion.
