The urinary system is compriesed of the organs, tubes, muscles, and nerves that work together to create, store, and carry urine.  This includes two kidneys, two ureters, the bladder, two sphincter muscles, the urethra, and - in men - the prostate.  Your body takes nutrients from food and uses them to maintain all bodily functions including energy and self-repair. After your body has taken what it needs from the food, waste products are left behind in the blood and in the bowel. The urinary system works with the lungs, skin, and intestines-all of which also excrete wastes-to keep the chemicals and water in your body balanced. Adults eliminate about a quart and a half of urine each day. The amount depends on many factors, especially the amounts of fluid and food a person consumes and how much fluid is lost through sweat and breathing. Certain types of medications can also affect the amount of urine eliminated.
