Question

Quizplus · Accepted Answer

Sympathetic stimulation of the kidney results in vasoconstriction of the afferent arterioles, triggering renin release and reducing blood flow to the kidneys. These actions result in renal ischemia, but they also help to maintain blood pressure. However, sympathetic stimulation does not increase the glomerular filtration rate. In fact, it may reduce GFR due to reduced blood flow to the kidney.
