The chief force pushing water and solutes out of the blood across the filtration membrane is ________.
A) the ionic electrochemical gradient
B) glomerular hydrostatic pressure (glomerular blood pressure)
C) protein-regulated diffusion
D) the size of the pores in the basement membrane of the capillaries

Question

Quizplus · Accepted Answer

The chief force pushing water and solutes out of the blood across the filtration membrane is glomerular hydrostatic pressure (glomerular blood pressure). This pressure is created by the pressure of blood flowing into the glomerulus and is responsible for the bulk flow of water and small solutes out of the blood and into the surrounding Bowman's capsule.
