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.
Released in response to increased atrial pressure. Afferent and efferent arteriole, distal convoluted tubule (DCT). Afferent arteriolar dilation and efferent arteriolar constriction leading to an overall increase in GFR and increase in sodium filtration. At the DCT, it inhibits sodium uptake to ensure volume loss.
