Elements of Human Body

Clinical Composition of Human Body

More than 93 per cent of the human body consists of three chemical elements-oxygen (65%), carbon (18.5%), and hydrogen (10%). 

Nitrogen (3%), calcium (1.5%), and phosphorus(1%) are also present in significant amounts.

At least 54 chemical elements feature in total, but most of these are tiny traces.

Do you Know?

A10-YEAR-OLD'S BODY CONTAINS 66 GRAMS OF POTASSIUM, THE SAME AMOUNT AS IN 156 BANANAS.

Elements in the Human Body

1.Oxygen in Human Body- 65%

About two-thirds of the body is oxygen. 

Most of the oxygen is bonded with hydrogen to form H2O - the chemical formula for water.

2.Hydrogen  in Human Body- 10%

Hydrogen is the most common element in the universe.

The hydrogen has the tiniest atoms, and is mostly bonded with carbon or oxygen in the body.

3.Carbon in Human Body 18.5%

Nearly one-fifth of the body is carbon, the same element that coal,

diamond, and the lead of pencils are made from.

4.Others in Human Body- 6.5%

Other elements less than 1.0%

Iron 0.006%

Sodium 0.2%

Potassium 0.4%

Phosphorus 0.4%

Calcium 1.5%

Nitrogen 3.2%

5.Precious elements in Human Body

The human body contains a tiny amount of gold - less than the weight of a grain of sand. 

Most of the body's gold is in the blood.

6.Carbon Compounds in Human Body

The human body is made from substances containing the element carbon. 

These carbon compounds are called organic compounds, these often contain hydrogen and oxygen, too. 

Although organic compounds are based on only a few elements, they produce more than 10 million different compounds.

Four main types of carbon compounds exist inside the human body.

Nucleic acids

The molecules DNA and RNA carry all the instructions for making the proteins that our bodies are made of. 

They also carry code that controls how cells work and reproduce.

Proteins

Proteins are vital body molecules.

 Organs Such as the brain are made of protein, as well as muscles, connective tissues, hormones that send chemical messages and antibodies that fight infection.

Fats

Fats are made from carbon and hydrogen atoms. 

They form the outer barrier of cells. 

The layer of fat beneath the skin stores energy and helps the body to keep out the cold.

Carbohydrates

Carbohydrates are made from carbon, oxygen, and hydrogen, and are the body's main source of energy. 

Carbohydrates circulate in the blood as sugar, or are stored in the liver and muscles.
