The glomerular capillary blood pressure is higher than capillary pressure elsewhere in the body, primarily because the afferent arteriole has a larger diameter than the efferent arteriole.

Question

Quizplus · Accepted Answer

The larger diameter of the afferent arteriole compared to the efferent arteriole creates a resistance difference, which results in increased pressure within the glomerular capillaries. This higher pressure allows for filtration of blood through the glomerulus and formation of urine.
