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 afferent arteriole in a nephron is a larger diameter then the outgoing efferent arteriole and this increase the blood pressure in the glomerulus capillaries resulting in t â¦ he ultrafiltration of the blood into the Bowman's capsule.
