Looking at the excretion of Urea (nitrogen – toxic to the body and cannot be stored) the original form is amino acids. This is the role of the liver and kidneys
Liver – amino acids are broken down and turned into urea. Released into the blood stream where it circulates to the kidneys
Kidneys – will filter urea from blood, it is added to water to form urine, where it collects in the bladder to be excreted (peeing) the filtered blood returns to circulation.
