The renal medulla is split up into a number of sections, known as the renal pyramids. Blood enters into the kidney via the renal artery, which then splits up to form the arcuate arterioles. The arcuate arterioles each in turn branch into interlobar arterioles, which finally reach the glomeruli.he renal medulla only receives about 10% of all the blood flowing through the kidneys. You could say that the function of the renal medulla, or the kidney in general, is maintaining homeostasis of a large number of solutes and water.
