E)none of the above

Question

Quizplus · Accepted Answer

All three mechanisms (autoregulation, myogenic activity, and vasoactive responses in the afferent arteriole) are involved in regulating the glomerular filtration rate. Autoregulation maintains a constant blood flow to the glomerulus despite changes in blood pressure, myogenic activity causes the afferent arterioles to constrict when blood pressure increases and dilate when blood pressure decreases, and vasoactive responses in the afferent arteriole can cause either constriction or dilation, depending on the signals received from hormones and other factors.
