The Variation of the Kidneys

As these are branch, as these continue to branch out, we're going from the little center entry point of the Harlem, all the way out to the outer exterior of the kidneys. You can actually have between about five to 18 variations in kidney structure. And if you were to cut the kidney into an anterior posterior or front and back section, you would actually see that the medulla is much darker than the cortex.
