  • EXCRETION
    • STAGE 1
      • Blood circulates to the liver and the amino acids are broken down and converted into UREA
    • STAGE 2
      • The Urea re-enters the bloodstream and circulates to both KIDNEYS
    • STAGE 3
      • Kidneys will filter the urea from the blood and the urea will be added to the water to form URINE
    • STAGE 4
      • Urine drains down the URETER to collect in the bladder
    • STAGE 5
      • Urea is now in the bladder in the form of urine and will be removed from the body
    • STAGE 6
      • The FILTERED BLOOD returns to the circulation and the process will happen again
