in the liver
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.

Yes they do. Many organisms including mammals, fish, fungi and microorganisms do excrete urea.
The kidneys remove urea from the blood and excrete it in urine. Urea is a waste product formed from the breakdown of proteins in the liver.

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.
It's called the Bosch-Meiser urea process. See https://en.wikipedia.org/wiki/Urea
The waste form of nitrogen formed in the liver and carried in the bloodstream is urea. Urea is produced in the liver through the breakdown of proteins and is removed from the body through the kidneys in urine.
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.
Urea is a waste product formed in the liver from ammonia and is excreted by the kidneys in urine. Its main consequence is the removal of nitrogenous waste from the body, helping to maintain proper nitrogen balance. High levels of urea in the blood can indicate kidney or liver dysfunction.
The molecular formula of the urea is NH2-CO-NH2. The proteins are long chain of many amino acids. Urea is formed out of metabolism ( break down) of the amino acids.
