The liver is the organ that produces urea in mammals. Here are the steps of how it happens:

1. Protein Breakdown: The process begins with the breakdown of proteins in the liver. Proteins are made up of amino acids, which contain nitrogen. When proteins are broken down, this nitrogen is released.

2. Ammonia Formation: The nitrogen then combines with hydrogen to form ammonia. Ammonia is toxic to the body, so it needs to be converted into a less harmful substance.

3. Urea Cycle: This is where the urea cycle comes in. The liver cells convert the ammonia into urea through a series of chemical reactions known as the urea cycle.

4. Urea Transportation: The urea is then transported from the liver to the kidneys via the bloodstream.

5. Urea Excretion: Finally, the kidneys filter out the urea from the blood, which is then excreted from the body in the form of urine.
