What is the most important element in the human body?
The most important structural element, and the reason we are known as carbon-based life forms. About 12 per cent of your body’s atoms are carbon. The hydrogen atoms in your body were formed in the Big Bang.
Why is hydrogen important to the human body?
The most important function of hydrogen in the human body is to keep you hydrated. Water is made up of hydrogen and oxygen and is absorbed by the cells of the body. Therefore, it is a crucial element which is used not in our body but also as a fuel, in military weapons etc.
Why we are made of stardust?
When stars get to the end of their lives, they swell up and fall together again, throwing off their outer layers. If a star is heavy enough, it will explode in a supernova. So most of the material that we’re made of comes out of dying stars, or stars that died in explosions. And those stellar explosions continue
