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.
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.
Yes, oxaloacetate contributes to the urea cycle by combining with carbamoyl phosphate to form citrulline. This is an important step in the conversion of ammonia into urea for excretion.
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.

Urea
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 and Salts
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.
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.
