What is the purpose of the urinary ducts?

The urinary ducts, primarily the ureters, serve to transport urine from the kidneys to the bladder. They are muscular tubes that use peristaltic contractions to propel urine downward. This ensures that urine is efficiently moved and stored until it is excreted from the body through the urethra. Additionally, the urinary ducts help regulate the flow and pressure of urine during storage and elimination.
