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 kidney s. The afferent arterioles later diverge into the Capillary capillaries of the glomerulus kidney glomerulus . Regulation When renal blood flow is reduced indicating hypotension or there is a decrease in sodium and chloride ion concentration, the macula densa of the distal tubule releases prostaglandins , which cause the juxtaglomerular cells lining the afferent arterioles to release renin , activating the renin angiotensin aldosterone system , to increase blood pressure and increase retention of sodium ions via aldosterone . The macula densa cell can also increase the local blood pressure of the afferent arterioles by increasing the synthesis of nitrous oxide or decreasing the synthesis of adenosine or adenosine triphosphate ATP . If the afferent arterioles are constricted then the blood pressure in the capillaries of the kidneys will drop.
