Urinary system, illustration. Urine is produced in the kidneys (top) where waste products are filtered from the blood. The urine is passed the bladder (bottom) via the ureters. It is evacuated from the body via the urethra by relaxing a set of sphincter muscles. The urinary system can be divided into the upper and lower urinary tracts. | |
