Hydrostatic-osmotic Pressure Interactions: Net Filtration Pressure (NFP) NFP—comprises all forces acting on capillary bed NFP = (HPc + OPif) – (HPif + OPc) Net fluid flow out at arterial end Net fluid flow in at venous end More leaves than is returned Excess fluid returned to blood via lymphatic system. Figure 18.17 Bulk fluid flow across capillary walls causes continuous mixing of fluid between the plasma and the interstitial fluid compartments, and maintains the interstitial environment 39
