So on this side of the kidney, we have the renal vein shown in blue. We have the renal arteries shown in red. And we have the ureter shown in green. On the other side we have the renal capsule, the renal cortex, the renal medulla, our renal pelvis, the renal pyramids, which are these brown sections here. And we have the nephron shown in purple. Now, this diagram only shows a single nephron, but actually we have over a million nephrons within this single kidney.
