Which forces create passive transport of water in the proximal tubule? (Select all that apply.)
A)Peritubular capillary hydrostatic pressure
B)Peritubular capillary oncotic pressure
C)Interstitial hydrostatic pressure
D)Interstitial osmotic pressure
E)Peritubular capillary osmotic pressure

Question

Quizplus · Accepted Answer

The osmotic force generated by active sodium transport promotes the passive diffusion of water out of the tubular lumen and into the peritubular capillaries. The elevated oncotic pressure of the blood in the peritubular capillaries further enhances the passive transport of water. Peritubular pressures are not forces that create passive transport of water in the proximal tubule.
