The urinary system, also known as the renal system, consists of the kidneys, ureters, bladder, and the urethra. Each kidney consists of millions of functional units called nephrons.
The Urinary System is a filtering systm. Just like you have an air filter in your home or an oil filter in your car, you have a filtering system in your body. The urinary system filters out excess fluid and other substances and biochemical goo from your bloodstream. Some fluid will get reabsorbed by your body but for the most part, the excess fluid is expelled as urine (fluid waste).
