The internal structure of the kidney is divided into two main areas... a light outer area called the renal cortex, and a darker inner area called the renal medulla. Within the medulla there are eight (8) or more cone-shaped sections known as renal pyramids.
The most actively working parts of the kidneys are tiny structures called nephrons. Each normal nephron, generally, works day and night to get rid of wastes in the blood. And each kidney has about 1 million tiny filtering units. Two major parts of the nephron are the renal corpuscle and the renal tubule.
