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.
Each kidney contains about a million tiny structures called nephrons. A nephron has a cup-shaped Bowman's capsule leading into the renal tubule. The two sections of each nephron extend across the two different regions of the kidney:1  the Bowman's capsules are found within the outer cortex region. 2  the renal tubules run from the cortex into the darker medulla.ach kidney contains about a million tiny structures called nephrons.
