what is the chief nitrogenous waste product present in the urine of the human being which organ produces it
Answers
Urea is the major nitrogenous waste product, making up some 80% of it. Urea is formed in the liver, and is excreted by the kidneys in the urine along with the other types of protein waste products. The destruction of proteins in the body gives rise to two classes of waste products: nitrogenous and non-nitrogenous.
Mammals, including humans, are the primary producers of urea. Because they secrete urea as the primary nitrogenous waste product, they are called ureotelic animals. Urea serves an important role in the metabolism of nitrogen-containing compounds by animals.
Two major nitrogenous waste products, urea and ammonium (NH₄⁺), are produced in humans when proteins are oxidized, and in this manuscript their excretions are examined from two perspectives.
