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.
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.fferent always means a road IN, while efferent always means the way out. So this arteriole is a connector between the (interstate highway) _renal artery_ and the (residential street) capillaries of a nephron's glomerulus. This is where filtration occurs in your kidney.
