Major Elements in the Human Body


Major Elements in the Human Body:

All matter, living or not, be it any form solid, liquid, or gas is made up of one or more, of only 106 elements found on Earth. Ninety-two of these elements occur naturally. The other 14 are man-made, and they break down in a fraction of second. The 92 natural elements can likewise break down, but only over millions of years. For most purposes, scientists don’t consider them as breaking down.

Of the 92 normally naturally found elements, just 26 are found in the human body. Of these 26 elements, 6 of them make up about the whole weight of living things. The other 20 components are though important to sustain life but they occur in such minute quantities that they’re referred to as “trace” elements.

The six major elements found in living things are hydrogen, oxygen, carbon, nitrogen, phosphorus, and calcium.


Hydrogen, a gas, is the most abundant element in the universe. Even though it’s a gas, about 10 percent of the total weight of plants and animals is hydrogen.


Oxygen is likewise a gas. Oxygen accounts for about 63 percent of a typical animal’s weight, and about 77 percent of a typical plant’s weight.


Carbon is a component that is natural to nearly everybody. Carbon makes up nearly 19 percent of a typical animal’s weight and 12 percent of a typical plant’s weight.


Nitrogen, another gas, makes up around 79 percent of the Earth’s air. It’s also an important component of the genes and proteins of all living things. About 4 percent of an animal’s weight and 1 percent of a plant’s total weight is made up of nitrogen.


Phosphorus is not found is a pure form in nature. It is highly reactive gas and it reacts with everything including with air. But a certain amount is necessary for life. Phosphorus comprises just less than 1 percent of an animal or plant’s total weight.


Calcium is likewise reactive and is also not found in natural form in nature. Hardly any plants have calcium in significant amounts, but for animals, especially mammals, calcium makes up about 2 percent of their total body weight, mostly in the form of bone tissue. Calcium is also necessary for muscle contraction.
