∙ 13y agoIt depends on if you are measuring by mass or by moles.
The human body is estimated to be over 65% water (H2O) by varying estimates.
Hydrogen is also part of every "hydrocarbon" in the body. However, it is also the lightest of the elements.
So, in moles, your top 3 elements would be: Hydrogen, Oxygen, and Carbon.
However, in mass they are reversed as: Oxygen, Carbon, and Hydrogen.
