The liver
Our bodies use it to facilitate the synthesis of amino acids.
The liver produces urea when it metabolises (breaks down) proteins. This is done in hepatocytes (liver cells). Amino acids are first broken down into ammonia, which is highly soluble and toxic in the blood plasma, so ammonia is joined with carbon dioxide to make urea, this is less soluble and less toxic but a build up of urea is toxic in the blood. Urea is then transported in the blood to be filtered out by the kidneys.
All cells make urea, it is a waste product. The urea is processed by the kidneys (reabsorbing most of the water) then transfered by the ureters to the urinary bladder.
Urea acts as a ligand in the synthesis of chromium acetylacetonate (acac) complex by coordinating to the chromium ion. It helps to stabilize the complex by forming bonds with the chromium center, thereby influencing the geometry and properties of the resulting complex. Urea also assists in controlling the reaction conditions and promoting the formation of the desired chromium acac complex.
Urea can be dangerous if ingested in large quantities as it can cause irritation to the gastrointestinal tract and potentially lead to dehydration and electrolyte imbalances. Exposure to high levels of urea in the blood can also lead to kidney damage and organ failure.
In the Kidneys
All amino acids
It's called the Bosch-Meiser urea process. See https://en.wikipedia.org/wiki/Urea
The organ that excretes Urea compounds are the kidneys, BUT they do not excrete HEAT. No organ of the human body EXCRETES heat.
The skin uses sweat to excrete water and urea.
They've lost the subsequent enzymes required for catalyzing the synthesis of urea into ammonia.

yes they can.The bacteria in their forstomach use the N of it to synthesis protein.
Urea is primarily produced in the liver as a waste product of protein metabolism. It is then excreted by the kidneys through urine.
