Urinary System, systema urinarium — General Overview

The Urinary system is a system comprising the Urinary Organs, organa urinaria, which are responsible for the Formation and Excretion of Urine. The Organs of the urinary system share a common embryological origin with the reproductive systems and are closely related both morphologically and functionally.

The urinary organs, organa urinaria, are subdivided into urine-producing organs, organa uropoetica, and urine-excreting organs, organa uroefferentia. The Kidneys, renes, [nephros], serve as the primary urine-producing organs and play a vital role in maintaining the overall Homeostasis of the Organism. The urinary organs eliminate Metabolic waste products in the urine, predominantly nitrogenous compounds such as urea, uric acid, creatinine, and ammonia (which is synthesized in the kidneys). In addition, salts of oxalic, orthophosphoric, and carbonic acids, as well as Vitamins and Hormones, are excreted in the urine. The kidneys also eliminate microbes and toxic substances from the body.
