Verified step by step guidance1
Understand the function of each organ listed in the urinary system: Kidney, Ureter, Urethra, and Bladder.

The ureter is a tube that carries urine from the kidney to the bladder, and does not play a role in water reabsorption.
The urethra is a tube that carries urine from the bladder to the outside of the body, and does not play a role in water reabsorption.
