Oxygen is the most abundant element found in the human body, making up about 65% of the total mass of a human. It is a critical component of many biological compounds, including water and most organic molecules. Carbon and hydrogen are also important constituents of many biological molecules, but they are not as abundant as oxygen. Calcium is present in bones and teeth, but it is not as abundant as oxygen either. Water is not an element, but a compound made up of hydrogen and oxygen.
