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.
Former Republican President Ronald Reagan is widely recognized as one of America's best presidents for economic expansion. But his party's overall economic track record isn't nearly as sterling. Michael Evans/The White House/Getty Images.
The term Reaganomics was used by both supporters and detractors of Reagan's policies. Reaganomics was partially based on the principles of supply-side economics and the trickle-down theory. These theories hold the view that decreases in taxes, especially for corporations, offer the best way to stimulate economic growth.
