Urinary System


The urinary system is a part of the body that clears waste from the blood and sends it to the bladder, where it’s stored until and released during urination.

The urinary system includes:

  • Kidneys: These bean-shaped organs filter the blood and remove waste products.
  • Ureters: Urine travels from each kidney through the ureters to the bladder.
  • Bladder: This balloon-shaped organ stores urine until urination. It has muscles that relax and squeeze to expel the urine.
  • Urethra: This tube carries urine from the bladder outside the body during urination.
