The kidneys remove wastes and excess water from the blood to produce urine. Urine passes from the kidneys to the bladder via two narrow tubes called ureters. To discharge waste when the bladder is full, a person urinates through the urethra. The ureters are two tubes that connect the kidneys to the bladder and discharge urine. Each ureter is a muscular tube that connects to the bladder and drains it. Smooth muscular contractions in the walls of the ureters convey urine in little spurts into the bladder, which stores pee before it can be removed, over time.
