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. WebTranscribed image text: QUESTION 43 1 points Save Answer When the afferent arteriolar resistance is increased, O A. GFR decreases, slowing production of filtrate. This occurs … photo cdsWebIt is intuitive that increased resistance in either arteriole reduces total renal blood flow. However, differential or relative resistances can lead to various effects on renal blood flow and, subsequently, GFR. When the afferent arteriole resistance is high, P GC is reduced. photo cd viewer

How does changing the afferent and efferent arteriole affect GFR?

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 the … 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.
