THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Urine has large amounts of nitrogen, phosphorus, and potassium. Nitrogen content in urine is high, mostly in urea, which makes up more than 50 percent of the total organic acids. This includes urea from protein metabolism, sodium and potassium both of which come from food.

Detailed explanation-2: -Urea is a major organic component found in human urine, which is a waste product expelled by animals after being excreted from the kidneys. Urea, also known as carbamide, is a waste product after the production of proteins from the breakdown of amino acids.

Detailed explanation-3: -Urea (also known as carbamide) is a waste product of many living organisms, and is the major organic component of human urine. This is because it is at the end of chain of reactions which break down the amino acids that make up proteins.

Detailed explanation-4: -In humans, the synthesis of urea is the main route for the removal of waste nitrogen, which is generated by protein and amino acid metabolism. This process takes place in the liver via the urea cycle. Urea is then removed from the blood and excreted into urine by the kidneys.
