Increased afferent arteriole resistance
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 … WebMay 10, 2024 · Angiotensin II acts on the kidneys to produce a variety of effects, including afferent and efferent arteriole constriction and increased Na+ reabsorption in the proximal convoluted tubule. These effects and …
Increased afferent arteriole resistance
Did you know?
WebOct 1, 2003 · In the kidney, increasing perfusion pressure causes myogenic constriction of preglomerular resistance vessels, especially the afferent arterioles, and acts to prevent an excessive rise in the PGC when the systemic pressure is elevated. WebWhat happens when the efferent arteriole dilates? Increased blood volume and increased blood pressure will increase GFR. Constriction in the afferent arterioles going into the …
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 … 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.
WebMay 4, 2024 · An increase in the afferent arteriolar diameter (decrease in resistance) causes an increase in the glomerular capillary hydrostatic pressure and an increase in GFR. A … WebWhy increased resistance in AFFERENT arterioles results in reduced glomerular filtration rate (GFR) while increased resistance in EFFERENT arterioles results in elevated GFR? (2 points) This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer Question: 2.
WebKidney Perfusion As kidney perfusion pressure rises, an increase in afferent arteriole resistance occurs, thereby preventing the transmission of the increased pressure to the glomerulus.
