WebJul 12, 2010 · Catecholamine-induced vasoconstriction usually affects the efferent more than the afferent arterioles. The resultant increase in filtration fraction alters peritubular capillary hemodynamics so as to favor water and sodium reabsorption (i.e., decreased hydrostatic pressure and increased oncotic pressure). WebThe net filtration pressure (NFP) represents the interaction of the hydrostatic and osmotic pressures, driving fluid out of the capillary. It is equal to the difference between the CHP and the BCOP. Since filtration is, …
