- Pie charts of typical human body composition by percent of mass, and by percent of atomic composition (atomic percent). Almost 99% 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.

Elemental Composition of the Human Body Updated March 15, 2017. Here's a look at the chemical composition of the human body, including element abundance and how each element is used. Elements are listed in order of decreasing abundance, with the most common element (by mass) listed first. Approximately 96% of body weight consists of only four elements: oxygen, carbon, hydrogen, and nitrogen.

- The elemental composition of the human body can be looked at from the point of view of either mass composition, or atomic composition. To illustrate both views, the adult male human body is approximately 57% water, and water is 11% hydrogen by mass but 67% by count of atoms (i.e. 67 atomic percent). Thus, most of the mass of the human body is oxygen, but most of the atoms in the human body are hydrogen atoms. Both mass-composition and atomic composition figures are given below (see pie graphs and table).

- Oxygen is element that is found in the highest percentage by weight in the human body. The body consists of 65% oxygen, 18% carbon, 10% hydrogen, 3% nitrogen, 1.5% calcium, 1% phosphorus, and other elements with increments of less than 1%.

Elemental Composition of the Human Body By mass, oxygen is the most abundant element in the human body. If you think about it, this makes sense, since most of the body consists of water or H2O. Oxygen accounts for 61-65% of the mass of the human body.

Questions and Answers Hydrogen, oxygen and carbon make up about 99% of the average human. I'm going to cheat a little and leave out the other 1%, which is made up of trace elements (that is, stuff there's only a trace of in the body). Then, let's assume an average adult weighs 70 kilograms.

What Chemical Compounds Does the Human Body Consist of? Nitrogen (3%) is found in many organic molecules, including the amino acids that make up proteins, and the nucleic acids that make up DNA. Calcium (1.5%) is the most common mineral in the human body-nearly all of it found in bones and teeth.odium (0.15%) is another electrolyte that is vital for electrical signaling in nerves. It also regulates the amount of water in the body. Chlorine (0.15%) is usually found in the body as a negative ion, called chloride. This electrolyte is important for maintaining a normal balance of fluids.

Human body consists of Inorganic and Organic compounds 1 Carbohydrates are sugars and starches. 2  They are used as fuel by the body and to store energy. 3  Glucose is a simple sugar that is a main source of energy for the body. 4  The liver and muscles can link glucose molecule into long chains, producing glycogen, a large molecule that can be stored.he human body is made up of atoms, ions and molecules. Life processes depend on the organization and interaction of these chemical units. An atom is the smallest amount of the chemical element that has the characteristic properties of that element.

Human body Nervous system. As commonly defined, the human body is the physical manifestation of a human being, a collection of chemical elements, mobile electrons, and electromagnetic fields present in extracellular materials and cellular components organized hierarchically into cells, tissues, organs ,and organ systems.he largest organ in the human body is the skin. Covering the entire body, even the eyes, which have a transparent layer of skin called the conjunctiva, the skin offers protection from water, air, sunlight, injury, dirt, chemicals, and microorganisms.

- Most of the human body is made up of water, H2O, with cells consisting of 65-90% water by weight. Therefore, it isn't surprising that most of a human body's mass is oxygen. Carbon, the basic unit for organic molecules, comes in second. 99% of the mass of the human body is made up of just six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. 1  Oxygen (O) - 65% - Oxygen together with hydrogen form water, which is the primary solvent found in the body and is used to regulate temperature and osmotic pressure.

Dental Terms Bone: Bone is the substance that forms the skeleton of the body. It is composed chiefly of calcium phosphate and calcium carbonate. It also serves as a storage area for calcium, playing a large role in calcium balance in the blood. The 206 bones in the body serve several other purposes.

Skeletal System The skeleton makes up about 30-40% of an adult’s body mass. The skeleton’s mass is made up of nonliving bone matrix and many tiny bone cells. Roughly half of the bone matrix’s mass is water, while the other half is collagen protein and solid crystals of calcium carbonate and calcium phosphate.

- The human body includes the entire structure of a human being and comprises a head, neck, trunk (which includes the thorax and abdomen), arms and hands, legs and feet. Every part of the body is composed of various types of cells, the fundamental unit of life.he average height of an adult male human (in developed countries) is about 1.7–1.8 m (5'7 to 5'11) and the adult female is about 1.6–1.7 m (5'2 to 5'7). Height is largely determined by genes and diet. Body type and body composition are influenced by factors such as genetics, diet, and exercise.

- Skin is considered to be the largest organ of the human body with an average surface. area of 1.6–2 m2 and accounts for about 15% of the total body weight of an adult. human. It is the outer covering of the body and has multiple layers (2-3 mm thick) which protect underlying muscles, bones, ligaments and internal organs.
