Which factor would reduce the net filtration pressure the most?
A)vasodilation of the afferent arteriole
B)vasoconstriction of the efferent arteriole
C)a large increase in blood colloid osmotic pressure
D)a low capsular hydrostatic pressure
E)a high glomerular hydrostatic pressure

Question

Quizplus · Accepted Answer

Blood colloid osmotic pressure opposes filtration and is determined by the presence of proteins in the blood. A large increase in blood colloid osmotic pressure would reduce the net filtration pressure the most by opposing the hydrostatic pressure that drives filtration. Vasoconstriction of the afferent arteriole and vasodilation of the efferent arteriole would increase the net filtration pressure. A low capsular hydrostatic pressure and a high glomerular hydrostatic pressure would also increase the net filtration pressure.
