If you were to cut a kidney in half, you would see the following parts:
- Renal Capsule - a thin, outer membrane that helps protect the kidney
- Cortex - a lightly colored outer region
- Medulla - a darker, reddish-brown, inner region
- Renal Pelvis - a flat, funnel-shaped cavity that collects the urine into the ureters
If you look closely at the cortex and medulla, you can see many tiny, tubular structures that stretch across both regions perpendicular to the surface of the kidney. In each kidney, there are one million of these structures, called nephrons. The nephron is the basic unit of the kidney. It's a long, thin tube that is closed at one end, has two twisted regions interspaced with a long hairpin loop, ends in a long straight portion and is surrounded by capillaries.
