Which of the following determines the direction of respiratory gas movement?
A)gas solubility in water
B)partial pressure gradient
C)molecular weight of the gas molecule
D)temperature

Question

Quizplus · Accepted Answer

The direction of respiratory gas movement is determined by the partial pressure gradient. Respiratory gases will move from an area of higher partial pressure to an area of lower partial pressure until equilibrium is reached. Gas solubility in water, molecular weight of the gas molecule, and temperature do not play a significant role in determining the direction of respiratory gas movement.
