The urinary system filters the blood and removes liquid waste products from the body in the form of urine. Picture 1 shows where the organs of the urinary system are located inside the body. Picture 2 is an enlarged diagram of these organs.

Parts of the Urinary System

The major organs of the urinary system are:

  • Kidneys - filter the blood, keep the right balance of water in body tissues, and change liquid waste products into urine.
  • Ureters - long narrow tubes that carry urine from the kidneys to the urinary bladder.
  • Urinary bladder - a muscular pouch where urine collects and is stored until it is passed out of the body.
  • Urethra - narrow tube that passes through the penis and carries urine from the bladder to the outside.
