Urea is synthesised in the liver, from the oxidation of amino acids and/or ammonia. Look up "urea cycle" for details about this process. It is then transported (in the blood) to the kidneys and excreted to the bladder, and exits the body with the urine.
Not really. The excess amino acids are broken down to release the amine part which becomes ammonia. This ammonia combines with CO2 to form urea.
Yes they do. Many organisms including mammals, fish, fungi and microorganisms do excrete urea.
Urease breaks down the compound urea into ammonia and carbon dioxide.
A waste form of nitrogen formed in the liver and carried in the bloodstream to the kidneys is called urea. Urea is produced through the urea cycle, where ammonia, a toxic byproduct of protein metabolism, is converted into urea for safer excretion. The kidneys then filter urea from the blood and excrete it in urine.
Urea is predominantly carried in urine, which is produced by the kidneys and excreted through the urinary system. In the bloodstream, urea is carried in the form of urea nitrogen and is filtered by the kidneys to be excreted in urine.
Urea is a soluble form of nitrogen waste produced in the liver from ammonia. It is the primary nitrogenous waste product in mammals and most terrestrial animals.

They kidneys get rid of the urea produced by the liver. The skin also excretes a small amount of urea in the sweat.
Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals.
Yes they do. Many organisms including mammals, fish, fungi and microorganisms do excrete urea.
urea is a liquid in pee.
Urea is a form of chemical waste in mammals including humans that forms into urine. Urea is produced when the body breaks down proteins and amino acids and its liquid form can be combined with ammonia and carbon dioxide to be used in fertilizers and some medications.
Urea and Salts
Unlike mammals (which create urea) birds turn nitrogenous wastes into uric acid.This conserves water - as uric acid can be excreted as the thick white substance which is familiar in bird droppings. For mammals, urine consists of urea dissolved in water.
Urease breaks down the compound urea into ammonia and carbon dioxide.
