What Would Happen If the Arteriole That Supplies Blood to the Glomerulus

Question

What would happen if the arteriole that supplies blood to the glomerulus constricts?
A) Blood flow into the efferent arteriole would increase.
B) The glomerular filtration rate would decrease.
C) The hydrostatic pressure in the glomerulus would increase.
D) The protein concentration of the glomerular filtrate would increase.
E) The glomerular filtration rate would increase.

Accepted Answer

When the arteriole that supplies blood to the glomerulus constricts, it leads to a decrease in blood flow into the glomerulus, which in turn reduces the glomerular filtration rate (GFR) due to lower hydrostatic pressure in the glomerular capillaries.
