Rationale: An
increase in precapillary resistance caused by arteriolar
vasoconstriction lowers capillary hydrostatic pressure and reduces
filtration of water out of the circulation.
Increasing postcapillary resistance as with venoconstriction has the
opposite effect, as does elevating capillary hydrostatic pressure or
dilating precapillary sphincters. Hypoalbuminemia reduces plasma oncotic
pressure and thus favors osmotic loss of water out of the capillaries.
