Describe GFR autoregulation, and explain why it is important.
What will be an ideal response?
1. The myogenic response is the ability of the vascular smooth muscle to constrict or dilate to keep pressure and
flow constant, thereby keeping GFR constant. Vasoconstriction is more effective at this than vasodilation.
2. Tubuloglomerular feedback involves production of a paracrine, in response to increased GFR, which constricts
the afferent arteriole to decrease GFR. Autoregulation helps protect the filtration barriers from high blood pressures that could damage them.
