5
Q

a local mechanism that tends to keep the rate of glomerular perfusion and there for the GFR fairly constant over a range of arterial pressures between 80 and 180 mmHg

6
Q

as arterial pressure declines, the stretch on the afferent arteriolar smooth muscle decreases and the arterial relaxes, causing an increase in glomerular perfusion, an increase in arteriolar pressure causes the arteriole smooth muscle to contract and decrease glomerular perfusion

A

myogenic mechanism

Q

as the GFR in an individual nephron increases or decreases, the macula dense cells in the distal tubule sense the increasing or decreasing amounts of filtered sodium, when sodium filtration increases the macula dense cells stimulate afferent arteriolar vasoconstriction to decrease GFR

A

Tubuloglomerular feedback
