There are two types of nephrons, distinguished by their location in the kidney. Cortical nephrons are located in the renal cortex on the outside of the organ, while juxtamedullary nephrons are located deeper in the kidney, in the renal medulla. Each nephron is made up of a renal corpuscle and a renal tubule.The renal corpuscle provides the initial filtering component, while the renal tubule is responsible for reabsorption. The corpuscle is composed of the glomerulus and Bowman's capsule.he nephron is the basic functional and structural unit of the kidney, and each human kidney contains from 800,000 to one million of these units.
Your kidneys are bean-shaped organs, each about the size of your fist. They are located near the middle of your back, just below the rib cage. The kidneys are sophisticated trash collectors. Every day, your kidneys process about 200 quarts of blood to sift out about 2 quarts of waste products and extra water.ach kidney contains about 1 million nephrons. In addition to removing wastes, your kidneys release three important hormones: 1  Erythropoietin (eh-RITH-ro-POYeh-tin), or EPO, which stimulates the bones to make red blood cells. 2  Renin (REE-nin), which regulates blood pressure.
