A reduction in renal perfusion normally results in dilatation of the glomerular afferent arteriole and constriction of the glomerular efferent arteriole so that glomerular capillary hydrostatic ...
ATP hydrolysis releases free adenosine into the extracellular space, which in turn acts on adenosine A1 receptors in the afferent arterioles and causes local constriction, thereby reducing RBF and ...
