Which of the following is NOT a factor that influences the rate of gas diffusion through the respiratory membrane?
A) The partial pressure gradient of the gases
B) The thickness of the respiratory membrane
C) The diffusion coefficient of the gases
D) The temperature of the gases
E) The surface area of the membrane
Respiratory Membrane
The respiratory membrane is the thin barrier in the lungs where gas exchange occurs, allowing oxygen to enter the blood and carbon dioxide to be expelled.
Diffusion Coefficient
Measure of how easily a gas diffuses through a liquid or tissue.
- Understand the principles of gas exchange and the factors affecting it.

Final Answer :
D
Explanation :
The rate of gas diffusion through the respiratory membrane is primarily influenced by the partial pressure gradient of the gases, the thickness of the respiratory membrane, the diffusion coefficient of the gases, and the surface area of the membrane. The temperature of the gases is not a direct factor influencing the rate of gas diffusion in the context of the respiratory system, as the body maintains a relatively constant temperature.
