[QUOTE="PhilA, post: 2715675, member: 335010"] At first I was going to say carbon, with is the most common element on Earth, but remembering that a human body was almost 70% water , and knowing water is mainly hydrogen ( 2 atoms of hydrogen per every one atom of oxygen) why was the answer oxygen , and not hydrogen? I'm confused. Does the oxygen in the lungs tip it in favour of oxygen perhaps ? [/QUOTE]
