Question

Which of the following statements is FALSE about the glomerulus and the processes that occur there?

a. Capsular hydrostatic pressure refers to the pressure of fluid pressing on the capsule and opposes filtration
b. Net filtration pressure in the glomerulus is the difference between forces favoring filtration and forces opposing filtration
c. Blood from the afferent arteriole is filtered by size when it enters the glomerulus because of the many fenestrae.
d. Vasoconstriction of the efferent arteriole lowers glomerular filtration rate.

Answer 1

The correct answer is option D.

Step-by-step explanation:

The vasoconstriction or the narrowing of the blood vessels regulate the filtration rate of the glomerulus. The afferent arteriole vasoconstriction decreases the flow of blood to the glomerulus thus, decreases the filtration rate

The vasoconstriction of the efferent arteriole increases the glomerular filtration rate due to the increase in the blood level in the glomerular capillaries.

Thus, option D is the correct option.
