The genitourinary system includes organs involved in the formation and excretion of urine (kidneys, ureters, urinary bladder, two sphincter muscles, urethra) together with those involved in sexual reproduction. Also called urogenital system.
The urinary system is the organ system that produces, stores, and eliminates urine. In humans it includes two kidneys, two ureters, the urinary bladder, two sphincter muscles, and the urethra. The analogous organ in invertebrates is the nephridium.
