Each arcuate artery supplies several interlobular arteries that feed into the afferent arterioles that supply the glomeruli.
2.
The interlobar arteries then supply blood to the arcuate arteries that run through the boundary of the cortex and the medulla.
3.
The larger blood vessels ( interlobar and arcuate arteries ) show reduplication of internal elastic lamina along with fibrous thickening of the media ( fibroelastic hyperplasia ) and the subintima.
4.
The renal artery enters into the kidney at the level of the first segmental artery, which divides into 2 or 3 lobar arteries, then further divides into interlobar arteries, which further divide into the arcuate artery, which leads into the interlobular artery, which form afferent arterioles.
5.
"' Interlobular arteries "'( or "'cortical radiate arteries "'or "'cortical radial arteries "') are renal blood vessels given off at right angles from the side of the arcuate arteries looking toward the cortical substance.
