Smooth muscle cells in the walls of the afferent and efferent arterioles dilate or constrict as needed in response to changes in blood pressure. This process of autoregulation is called the ________.
A) myogenic mechanism
B) tubular secretion
C) tubuloglomerular feedback
D) glomerular filtration
E) tubular reabsorption

Question

Quizplus · Accepted Answer

The myogenic mechanism is a process of autoregulation where smooth muscle cells in the walls of arterioles (including afferent and efferent arterioles of the nephron) respond to changes in blood pressure by dilating or constricting. This helps maintain a relatively stable glomerular filtration rate despite fluctuations in systemic blood pressure.
