WebDilation of the afferent arterioles has the opposite effects. Constriction of the efferent arterioles also increases the vascular resistance so it reduces RBF. The pressure within the glomerular capillaries may increase, however, because the flow is slowed by efferent arteriolar constriction. WebConstriction of the afferent arterioles means that there is a decrease in vessel diameter, which further means that there is an increase in resistance.

The Afferent And Efferent Arterioles Of The Glomerulus

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. WebAn afferent arteriole connects the renal artery to the glomerular capillary network in your kidney's nephron, starting the filtering process. It also takes action that controls blood … list of traditional christian christmas songsWebConstriction of either the afferent or efferent arterioles can alter the glomerular hydrostatic pressure, P GC, that drives ultrafiltration.

WebMar 8, 2024 · The efferent arteriole has a smaller diameter in the basal state; as a result, further constriction at this site will produce a greater increase in resistance than at 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.
