<prompt> Answer this question truthfullyWhat is the myogenic mechanism of renal autoregulation, and how do renal afferent arterioles respond to increased stretch on the arterial wall according to this mechanism?  <response>: <reason> The myogenic mechanism of renal autoregulation is a mechanism by which the renal system regulates its own blood flow. According to this mechanism, renal afferent arterioles contract in response to increased stretch on the arterial wall.
