Considering the arrangement of blood vessels in the vertebrate kidney bringing blood to and from the glomerulus, a(n) _______ in the diameter of the _______ could result in an increased rate of filtration.

Question

Quizplus · Accepted Answer

The afferent arteriole is the vessel that brings blood into the glomerulus, and an increase in its diameter would increase the rate of blood flow into the glomerulus, resulting in an increased rate of filtration. A decrease in the diameter of the afferent arteriole would have the opposite effect, decreasing the rate of filtration. Changes in the diameter of the efferent arteriole or peritubular capillaries would not have as direct an effect on filtration, and the renal venule carries blood away from the kidney and does not directly affect filtration.
