Urea is the most abundant nitrogenous waste found in urine. It is a byproduct of protein metabolism in the liver and is excreted by the kidneys. Uric acid is another nitrogenous waste, but it is not as abundant in urine as urea. Ammonia is toxic to the body and must be converted to urea before it can be excreted. Creatinine is a waste product of muscle metabolism and is also excreted by the kidneys, but it is not as abundant in urine as urea.
