Renal Artery Renal artery arises directly from abdominal aorta and enters the kidney through the hilus While passing through renal sinus the renal artery divides into many segmental arteries Segmental Artery Segmental artery subdivides into interlobar arteries Interlobar Artery Interlobar artery passes in between the medullary pyramids At the base of the pyramid it turns and runs parallel to the base of pyramid forming arcuate artery Arcuate artery Each arcuate artery gives rise to interlobular arteries Interlobular Artery Interlobular arteries run through the renal cortex perpendicular to arcuate artery From each interlobular artery numerous afferent arterioles arise Afferent Arteriole Afferent arteriole enters the Bowman capsule and forms glomerular capillary tuft After entering the Bowman capsule the afferent arteriole divides into 4 or 5 large capillaries Glomerular Capillaries Each large capillary divides into small glomerular capillaries which form the loops And the capillary loops unite to form the efferent arteriole which leaves the Bowman capsule Efferent Arteriole Efferent arterioles form a second capillary network called peritubular capillaries which surround the tubular portions of the nephrons Thus the renal circulation forms a portal system by the presence of two sets of
