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 kidney is a complex organ made of thousands of tiny units called nephrons. Nephrons are the basic functional and structural unit of the kidney. The mammalian kidneys have two types of nephrons, namely, juxtamedullary nephron and cortical nephron.
