Explanation:
Detailed explanation-1: -Vasodilatation of the afferent arteriole will increase blood supply to the capillaries resulting in a higher hydrostatic pressure and increased urine production. Vasoconstriction of the efferent arteriole decreases outflow, and so increases glomerular pressure and urine output.
Detailed explanation-2: -An 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 pressure.
