- 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
- STAGE 1
