The urinary tract is the network of organs and tubes that process and carry urine out of the body. The kidneys, ureters, bladder, and urethra are part of the urinary tract.

Each part of the urinary tract has a specific function.

• The kidneys make urine.
• The ureters are tubes that carry urine from the kidneys to the bladder.
• The bladder stores urine.
• The urethra is a tube that carries urine from the bladder to the outside of the body.

The kidneys and ureters are the upper urinary tract. The bladder and urethra are the lower urinary tract.
