Question

Quizplus · Accepted Answer

The glomerulus is unique in that it is drained by an efferent arteriole as opposed to most capillaries that are drained by a venule. This allows for the formation of a pressure gradient in the glomerulus, which is necessary for the process of filtration.

Other choices are incorrect because: 
A) Many capillaries in the body have a basement membrane. 
B) The glomerulus is actually highly permeable and allows for the filtration of many substances. 
D) The blood pressure in the glomerulus is actually higher than in most other capillary beds in the body.
