Question

Quizplus · Accepted Answer

Autoregulation 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 constriction or dilation of the afferent arterioles in response to changes in perfusion pressure, which helps to maintain a stable GFR. Secretion of atrial natriuretic peptide and renin, as well as actions of the parasympathetic nervous system, are not related to autoregulation.
