Sympathetic stimulation of the afferent and efferent arterioles during exercise leads to increased net filtration pressure and decreased urinary output.

Question

Quizplus · Accepted Answer

Sympathetic stimulation during exercise causes vasoconstriction of both afferent and efferent arterioles, which decreases the glomerular filtration rate (GFR) and leads to decreased urinary output, but it does not increase net filtration pressure; it actually reduces the flow of blood through the kidneys, thus affecting filtration pressure negatively.
