The "Urinary System" may
also be called the "Renal System" because
this group of inter-connected body parts process a liquid substance called urine via
specialist organs called the kidneys. The word "renal" means "pertaining
to the kidneys", so this group of tissues and organs is either
named after the substance it processes (urine; "Urinary System"),
or the organ that does most of the work (kidneys, "Renal System").
