    The human body is organized into different hierarchical levels. First distinguishes the apparatus (digestive, respiratory ... etc.). which in turn are composed of organs (heart, liver ...) , which in turn are made ​​up of cells. And of course, the cells are composed of molecules. Given that when the human reaches adulthood, the body consists of about one hundred billion cells, you can guess that the number of molecules for which we are made is enormous. In this ranking you can find the percentage that each chemical element in the total of our body.

    1               Hydrogen         63.00
    2         Oxygen         25.50
    3         Carbon         9.50
    4         Nitrogen         1.40
    5         Calcium         0.31
    6         Phosphorus         0.22
    7         Potassium         0.06

      Water is the most abundant molecule. But water is made up of two elements - hydrogen and oxygen.

    by number of atoms- hydrogen

    by weight - oxygen

    The most abundant element in the human body is oxygen. About two thirds (65%) of the human body is oxygen by mass.

    The most abundant metal in the human body is calcium.
