The kidneys are a pair of bean-shaped organs, each about the size of your fist.
They are located near the spine, below the rib cage, one on each side.
Your kidneys keep the blood clean and chemically balanced.
The kidneys filter 200 quarts of blood and produce 2 quarts of waste products and water each day. Wastes in the blood come mostly from the breakdown of food and beverages. If the kidneys did not remove these wastes, they would build up in the blood and damage the body.
The removal of wastes and water occurs in tiny structures in the kidneys called nephrons.
Your kidney has about a million nephrons. The nephron consists of a blood filtering component,
the glomerulus, that keeps proteins and cells in the bloodstream and allows fluid and wastes to pass through. It is connected to a long cylindrical tube know as a tubule. A complicated chemical exchange takes place in the tubule, as waste materials and water pass along it to become urine.
The wastes and water become urine, which flows to the bladder through tubes called ureters.
The bladder stores urine until releasing it through urination.
