WHERE YOUR ELEMENTS CAME FROM | APOD
The hydrogen in your body , present in every molecule of water , came from the Big Bang .
There are no other appreciable sources of hydrogen in the Universe .
The carbon in your body was made by nuclear fusion in the interior of stars , as was the oxygen .
Much of the iron in your body was made during supernovas of stars that occurred long ago and far away .
The gold in your jewelry was likely made from neutron stars during collisions that may have been visible as short duration gamma ray bursts or gravitational wave events .
Elements like phosphorus and copper are present in our bodies in only small amounts but are essential to the functioning of all known life .
The featured periodic table is color coded to indicate humanity's best guess as to the nuclear origin of all known elements .
The sites of nuclear creation of some elements , such as copper , are not really well known and are continuing topics of observational and computational research .
HUMAN BODY CHEMICAL COMPOSITION | FORESIGHT.ORG
The human body consists of ~7 x 1027 atoms arranged in a highly aperiodic physical structure . Although 41 chemical elements are commonly found in the body's construction ( Table 3-1 ) , CHON comprises 99% of its atoms . Fully 87% of human body atoms are either hydrogen or oxygen .
