Question

how is urine prevented from flowing back to you ureters

Answer 1

The urine formed in both the kidney is carried to the bladder by two narrow tubes, known as ureters. Ureters prevent the back flow of urine during urination, when the bladder contracts to pass urine to the urethra. If this function of the ureters is impaired, then diseases like, cystitis and kidney infection may occur. The urinary bladder is a triangular hollow organ, which stores urine, until it is expelled from the body. It is located in the lower abdomen region, and it has the ability to expand for storing urine and then, contract to expel it.
