A)has a basement membrane

D)is impermeable to most substances

Question

Quizplus · Accepted Answer

The glomerulus is unique in that it is drained by an efferent arteriole, which leads to the formation of a secondary capillary bed in the peritubular network of the renal medulla. This allows for the selective reabsorption of certain substances from the filtrate, such as water and electrolytes. The glomerulus also has a high blood pressure, which is maintained by the afferent arteriole, and a porous basement membrane that allows for the filtration of blood plasma into Bowman's capsule. Therefore, choices A, C, and D are incorrect.
