excess amino acids in the liver break down in a process called deamination,this splits the amino acids into ammonia which is broken down into urea using carbon dioxide, and carbohydrates which is broken down into glycogen and stored in the liver.In other words urea is formed in the liver as a result of deamination.

Urine is produced by most multicellular animals as a way of releasing waste and excess fluid from the body.
the source being waste and unfiltered liquids and minerals from the liver and kidneys
Many processes in the body produce nitrogen-containing wasted-products. This nitrogen will sometimes form ammonia, which is poisonous to the body.
In order to remove this poisonous ammonia from the body, ammonia is converted to urea which is non-toxic for the body, and more easily removed. This happens in the urea cycle.
Thus urea is a way of disposing leftover waste-nitrogen from our nitrogen metabolism.
Urea is a by-product of protein metabolism in the liver. It forms when the liver breaks down proteins in the body.
The blood passes through the liver at an increase lever of approximately 2 mg per cent.
The term for waste products of protein metabolism eliminated by the kidneys is urea. Urea is formed in the liver as a byproduct of protein metabolism and is filtered by the kidneys and excreted in urine.
The three waste products in living things are carbon dioxide, urea, and feces. Carbon dioxide is a byproduct of cellular respiration, urea is a byproduct of protein metabolism, and feces contain undigested food and waste products from the digestive system.
Ammonia is a toxic byproduct produced when the body breaks down proteins and lipids. It is converted to urea in the liver and excreted in urine.
Urea in mammals is formed from the breakdown of amino acids in the liver. Ammonia is first generated as a byproduct, which is then converted into urea through the urea cycle. This process involves several enzymes and cofactors that help transform ammonia into urea for excretion in the urine.
Three metabolic waste products excreted and eliminated by the urinary system are urea, a byproduct of protein metabolism, creatinine, a byproduct of muscle metabolism, and uric acid, a byproduct of nucleic acid metabolism.
