Describe the flow of blood through the kidney starting with the renal artery and ending with the renal vein

The renal artery provides the blood flow to the kidney. The renal artery first divides into segmental arteries, followed by further branching to form multiple interlobar arteries that pass through the renal columns to reach the cortex. The interlobar arteries, in turn, branch into arcuate arteries, cortical radiate arteries, and then into afferent arterioles. The afferent arterioles service about 1.3 million nephrons in each kidney.
