Elements Found in the Body
Let's look at the top elements found in the body:
Oxygen contributes to 65% of the weight of the human body. Most of the oxygen in the body is found in water. Water accounts for 60% of the body. Oxygen can be found in various places in the body, including in proteins, the lungs, and the blood.
Carbon accounts for 18% of the weight of the human body. There are many organic compounds in the body, and they all contain carbon. Carbon is essential for the functioning of the body's metabolism.
Hydrogen is responsible for 10% of the body's weight. The majority of hydrogen is found in the water in the body. Hydrogen is in every organic compound in the body.
Nitrogen enters the body through the food we eat. It accounts for 3% of the body's weight. Nitrogen is another crucial element in amino acids. Nitrogen is also an important part of DNA and RNA.
Calcium accounts for 1.4% of the weight of the human body. It can mostly be found in bones and teeth. The body also uses calcium to contract its muscles.
Phosphorus accounts for 1% of the weight of the body. Like calcium, it's found in bones and teeth. ATP and other molecules that are energy sources contain phosphorus.
Potassium is a key component to the function of the nerves in the body. It also helps keep the heartbeat regular. It accounts for 0.25% of the body's weight.
Sulfur also makes up 0.25% of the body's weight and can be found in amino acids (the building blocks of proteins). While 0.25% may not seem like a significant percentage, could you imagine if the body didn't have the sulfur needed for amino acids? The body would be unable to produce the proteins essential for life.
Sodium accounts for 0.15% of the body's weight. You've probably heard that too much sodium is bad for you. However, too little sodium is also harmful. Sodium is essential for the functioning of the nerves and muscles in the body.
Chlorine is responsible for 0.15% of the body's weight. It helps transport enzymes for essential processes in the body. It also reacts with hydrogen to form hydrochloric acid. Hydrochloric acid digests food in the stomach.
Magnesium makes up 0.005% of the body's weight. Magnesium helps build teeth and bones.

Answer:
Almost 50% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium. All 11 are necessary for life.
