How are the elements in the body related to each other?

Here’s a look at these elements in their pure form and their function in the human body. Note that the percentage are estimates. Hydration level (how much water you drink) makes a big impact on the amount of oxygen and hydrogen in your body and affects the relative composition of the rest of the elements in your body.
