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.
The afferent arterioles branch from the renal artery, which supplies blood to the kidneys.
The afferent arterioles later diverge into the capillaries of the glomerulus.
