The ureter in the urinary system serves to transport urine from the kidneys to the urinary bladder. Each kidney is connected to a ureter, and the ureters play a crucial role in the unidirectional flow of urine. Peristaltic contractions of smooth muscle in the ureter walls propel urine downward, overcoming gravity and facilitating its transport to the urinary bladder. The ureters prevent the backflow of urine by employing one-way valves and contribute to maintaining urinary system function by ensuring the efficient elimination of urine from the kidneys to the bladder for temporary storage until micturition occurs.
