Urea is formed in which organ?

Explanation:
Urea formation occurs in the liver. When amino acids are deaminated, ammonia is produced, and the liver detoxifies this ammonia by converting it into urea through the urea cycle. The urea then travels in the bloodstream to the kidneys, where it is filtered and excreted in urine. The kidneys handle excretion, not production; the lungs dispose of carbon dioxide, and the heart isn’t involved in making urea.
