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

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.
