Biological system: Difference between revisions

The urinary system is a bodily system responsible for producing, storing, and secreting [[urine]] (waste). It includes the [[kidneys]], [[urinary bladder]], urethra, and ureters. It also serves several important roles other than filtering out wastes; including maintain the [[water]] levels in the body, and control [[blood pressure]] and [[pH]] levels. After taking nutrients and vitamins from digested food and converting it to energy for the body to use, certain waste materials are left behind that need to be excreted from the body. Waste materials, both solid and liquid, are left in the bowel and in the [[blood]]. This is where the urinary system comes into play. Urea, which is the primary waste removed by the kidney, is the result of the breakdown of foods and vegetables that have [[protein]]. The urea is carried by the bloodstream to the [[kidneys]] where the filtration process begins.<ref name=intro1>[http://medicalcenter.osu.edu/patientcare/healthcare_services/urinary_bladder_kidney/anatomy_urinary_system/pages/index.aspx Anatomy of the Urinary System] The Ohio State Medical Center, 2007.</ref>
