Female urinary tract. Computer artwork of a naked woman with her urinary tract shown in red. The kidneys (upper centre left and right) filter waste products from the blood. The filtrate (urine) is passed down the ureters (tubes) to the bladder (lower centre), where it is stored. Urine is expelled from the body through the urethra below the bladder.
