Quizplus · Accepted Answer

Autoregulation in the kidney refers to the ability of the kidneys to maintain a relatively constant glomerular filtration rate (GFR) despite changes in systemic blood pressure. This is achieved through changes in the degree of constriction of afferent arterioles, which can dilate or constrict in response to changes in blood pressure to maintain a stable GFR. Sympathetic stimulation, aldosterone secretion, and ADH secretion can all affect renal function, but they are not part of the autoregulatory mechanism that maintains GFR.
