The urinary tract is a vital part of the human body's excretory system, responsible for eliminating waste products from the body in the form of urine. It consists of a series of organs that are involved in the production, storage, and elimination of urine. The urinary tract starts with the kidneys, which filter the blood and produce urine. The urine then flows through the ureters, which are tubes that connect the kidneys to the bladder.
