Path of Blood Through Kidney At rest, about 25% of cardiac output enters the kidneys to be filtered. The renal arteries branch off the descending aorta. Once in the kidney it branches into several interlobar arteries which travel up the renal columns, between the lobes. The arcuate arteries arch over the pyramids. From the arcuate arteries the interlobular arteries branch up into the cortex. The afferent arterioles branch off the interlobular arteries and enter the glomerular capsule. This cluster of capillaries in the glomerular capsule is called the glomerulus and is the only place filtration takes place. The efferent arterioles exit the glomerular capsule and branch into peritubular capillaries that reabsorb many of the nutrients filtered out of the blood in the glomerulus. Another branch of the efferent arterioles are the vasa recta which descend into the renal medulla and will be discussed later. The peritubular capillaries and vasa recta lead into the interlobular veins to the
