Which two factors affect how many gas molecules move across the respiratory surface in any given time?
A) moisture and transport proteins
B) moisture and surface area
C) partial pressure gradient and moisture
D) partial pressure gradient and surface area
E) transport proteins and surface area

Question

Quizplus · Accepted Answer

The rate of gas exchange across a respiratory surface is primarily influenced by the partial pressure gradient and the surface area available for diffusion. A higher partial pressure gradient increases the rate of diffusion, and a larger surface area provides more space for gas exchange to occur.
