The Human Body Elements

The Human Body elements The  human body   is made up of a number of certain   elements  including  oxygen,  carbon ,  hydrogen, nitrogen,  calcium  ,  phosphorus  and potassium.  Oxygen is the most abundant element in the body. The body's 43 kilograms (Mass of element in a 70-kg person) of oxygen is found mostly as a component of water, which makes up 70% of total body weight. Oxygen is also an integral component of all proteins, nucleic acids (DNA and RNA), carbohydrates, and fats. Rubidium is the most abundant element in the body (0.68 g) that has no known biological role (silicon, which is slightly more abundant, may or may not have a metabolic function). Vanadium is the body's least abundant element (0.11 mg) that has a known biologic role, followed by cobalt (3 mg), the latter being a constituent of vitamin B 12 . The last of the body's elements to be discovered was fluorine, by Moissan in 1886     ...
