What is the primary function of the ureter in the urinary system?

The primary function of the ureter is to connect the kidneys to the bladder. After the kidneys filter the blood to remove waste and excess fluid, they produce urine. This urine then flows from each kidney into the ureter, which serves as a tube that transports urine to the bladder for temporary storage. This anatomical connection is crucial for the proper functioning of the urinary system, ensuring that urine produced by the kidneys is efficiently delivered to the bladder where it can be held until it is ready to be eliminated from the body.
