Respuesta :
Afferent arteriolar vasoconstriction decreases blood flow into the glomerulus, which causes the glomerular-capillary blood pressure to decrease, leading to a(n) decrease in the net filtration pressure and a resultant decrease in the GFR.
What happens if the afferent arteriole is vasoconstriction?
Constriction of the afferent arterioles has two inpact
it increases the vascular resistance which lessens renal blood flow (RBF), and it lowers the pressure downstream from the constriction, which lower the GFR.
Thus, Afferent arteriolar vasoconstriction reduces blood flow into the glomerulus, which causes the glomerular-capillary blood pressure to lessens .
