Because of autoregulation, changes in mean arterial blood pressure between the range of 80 to 180 mm Hg do not directly produce changes in the GFR.

Question

Quizplus · Accepted Answer

Autoregulation of the GFR allows for the maintenance of a relatively constant filtration rate despite changes in mean arterial blood pressure within a range of 80 to 180 mm Hg. This is achieved through the constriction or dilation of afferent and efferent arterioles, which regulates the glomerular hydrostatic pressure and filtration rate. Therefore, direct changes in mean arterial blood pressure within this range do not significantly affect the GFR. However, outside this autoregulatory range, changes in mean arterial blood pressure can have significant effects on the GFR.
