The afferent arterioles are a group of blood vessels that supply the nephrons in many excretory systems.They play an important role in the regulation of blood pressure as a part of the tubuloglomerular feedback mechanism.he afferent arterioles are a group of blood vessels that supply the nephrons in many excretory systems.
The glomerulus is a tuft of small blood vessels called capillaries located within Bowman's capsule within the kidney. Between the capillaries and Bowman's capsule lies mesangium. Blood enters the capillaries of the glomerulus by a single arteriole called an afferent arteriole and leaves by an efferent arteriole.The capillaries are lined by a layer of cells (an endothelium) that has a unique structure, allowing blood components to be filtered, and resulting ultimately in the formation of urine. glomerulus receives blood from a single artery called the afferent artery. The afferent artery is a branch of an interlobular artery in the cortex of the kidney.
