Kidneys and urinary tract

The urinary system is made up of the kidneys, urethra, ureter, and bladder. This organ system is responsible for creating and excreting urine. Urinary system disorders range from generally harmless bladder infections to serious diseases such as renal cell carcinoma (kidney cancer) or chronic kidney failure.
