Document Summary

We can calculate blood flow (f) (p1 p2) is the pressure gradient: simply the pressure change between two points (p1 and p2, r is the resistance. Exchange of substances across the capillary capillaries are the main sites for the exchange of oxygen, nutrients, water, carbon dioxide, and waste. +6 mmhg (in the brain and kidneys) assume that there is no hydrostatic pressure in the interstitial fluid. If) will pull fluid out of the interstitial fluid contains little proteins, this force is low around 3 mmhg. Net direction of fluid movement, we need to calculate the net filtration pressure (nfp) using the following equation: Nfp = (pc pif ) ( p . Edema accumulation of fluid in the interstitial space causing swelling is called edema under normal circumstances, edema does not occur because the lymphatic system can remove any excess fluid certain conditions cause the accumulation of fluid, producing edema. Control of blood flow local control mechanisms (auto regulation)
