Detailed explanation-1: -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.
Detailed explanation-2: -Myogenic mechanisms in the kidney are part of the autoregulation mechanism which maintains a constant renal blood flow at varying arterial pressure. Concomitant autoregulation of glomerular pressure and filtration indicates regulation of preglomerular resistance.
Detailed explanation-3: -Blood vessels also contain muscle, and that muscle controls just how wide or narrow your blood vessels are at any given time. When blood vessels get wider, that’s vasodilation. The opposite process, when blood vessels constrict and get narrower, is called vasoconstriction.
