Which organ produces urea?

Explanation:
Production of urea happens mainly in the liver through the urea cycle, which detoxifies ammonia produced from amino acid breakdown. In hepatocytes, ammonia is converted first to carbamoyl phosphate and then through a series of reactions to form urea. This urea is released into the bloodstream and carried to the kidneys, where it is excreted in urine. The kidneys’ role is to excrete urea, not to produce it, while the pancreas and spleen are not involved in nitrogen disposal. So, the liver is the organ that produces urea.
