Quizplus · Accepted Answer

Intense sympathetic stimulation of the kidney leads to vasoconstriction of renal blood vessels, which decreases renal blood flow and subsequently can reduce the glomerular filtration rate (GFR), not increase it. This mechanism is part of the body's response to stress, diverting blood flow away from the kidneys and towards muscles and other organs more immediately necessary for a fight or flight response.
