WebHistamine decreases the resistance of the afferent and efferent arterioles and thereby increases RBF without elevating the GFR. Dopamine The vasodilator dopamine is produced by the proximal tubule. Dopamine has several actions within the kidney, such as increasing RBF and inhibiting renin secretion. WebAn increase in the afferent arteriolar diameter/radius results in decreasing the resistance causes an increase in the glomerular capillary hydrostatic pressure and an increase in GFR. A decrease in the diameter of the afferent arteriole has the opposite effect. PLEASE RATE IT AS HELPFUL, IF YOU UNDERSTAND IT.

WebThe afferent arterioles' constriction results in the increase in the pressure exerted on the walls of the afferent arterioles by the renal blood. This further, causes a decrease in the flow of the blood into the glomerulus and, in turn, the hydrostatic pressure of the glomerulus. Hence, the GFR (glomerular filtration rate) is decreased.

WebConstriction of the afferent arterioles has two effects: it increases the vascular resistance which reduces renal blood flow (RBF), and it decreases the pressure downstream from … WebNormally the afferent arteriole is of larger diameter than the efferent. This means there is high resistance as the blood is forced from a wider vessel to a narrower one and this promotes filtration. If the arterial blood pressure remains constant then contracting either vessel reduces blood flow as it increases resistance.
