Unformatted text preview: the sum of those that oppose filtration. The following contribute to the NFP: • The glomerular hydrostatic pressure (blood pressure in the glomerulus) promotes filtration. • The glomerular osmotic pressure inhibits filtration. This pressure is created as a result of the movement of water and solutes out of the glomerular capillaries, while proteins and blood cells remain. This increases the concentration of solutes (thus decreasing the concentration of water) in the glomerular capillaries and therefore promotes the return of water to the glomerular capillaries by osmosis. • The capsular hydrostatic pressure inhibits filtration. This pressure develops as water collects in the glomerular capsule. The more water in the capsule, the greater the pressure....
