WebJan 1, 2007 · Autoregulation of renal blood flow (RBF) is caused by the myogenic response (MR), tubuloglomerular feedback (TGF), and a third regulatory mechanism that is independent of TGF but slower than MR. The underlying cause of the third regulatory mechanism remains unclear; possibilities include ATP, ANG II, or a slow component of MR. WebJun 22, 2009 · The phenomenon of renal autoregulation is believed to be mediated by the combined and interacting contributions of 2 mechanisms, a faster myogenic and a slower tubuloglomerular feedback (TGF) system. 13–16,35 Recently, additional and even slower mechanisms have been postulated. 15 Although the myogenic and TGF mechanisms are … WebA) RAAS and myogenic mechanism B) tubuloglomerular feedback and myogenic mechanism C) RAAS and atrial Glomerulonephritis, or inflammation of the glomerulus, will result in leaky glomerular capillaries and damaged glomeruli, both of which will cause the GFR to decrease. eating a crow
