In the nephron (left), tiny blood vessels intertwine with urine-collecting tubes. Each 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.
The kidneys are bilateral bean shaped organs, located in the posterior abdomen. They are reddish-brown in colour. The main function of the kidneys is to filter and excrete waste products from the blood.They are also responsible for water and electrolyte balance in the body.Metabolic waste and excess electrolytes are excreted by the kidneys to form urine. Urine is transported from the kidneys to the bladder by the ureters.he kidneys lie retroperitoneally (behind the peritoneum) in the abdomen, either side of the vertebral column. The left and right kidneys are located at different vertebral levels: 1  Left kidney: T11- L2. 2  Right kidney: T12 â L3 (it is lower due to the presence of the liver).
