The role of the kidney:
- Excretion of Urea ( contains nitrogen - toxic to the body and cannot be stored)
- The original form of nitrogen are amino acids (used for growth but too much must be removed)
- Blood circulates into the liver and breaks down and converted into Urea.
- It re-enters the blood stream and circulates to both kidneys.
- The kidneys will filter the urea from the blood and will be added to water to form urine.
- The urine drains down the uterus to collect in the bladder. (in form of urine)
- The filtered blood returns to the circulation in the veins with the toxic amino acids and urea removed.
