Unformatted text preview: s Bulk Flow - This is the principal mechanism by which the distribution of fluid is maintained between the blood and the extracel l u capillary blood pressure (Pc) - this is the hydrostatic pressure exerted on the inside of the walls of the capillaries. It acts to forc e plasma-colloid osmotic pressure (pp) - this is the osmotic force acting to move water into the capillaries from the interstitial flui d interstitial fluid hydrostatic pressure (PIF) - this is the hydrostatic pressure exerted on the outside of the capillary walls. It acts t o...
