Body? Human body is made up of six elements: 1. Oxygen 43% , 2. Carbon 16%, 3. Hydrogen 7%, 4. Nitrogen 1.8%, 5. Calcium 1%, and 6. Phosphorus 0.780%. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium. All are necessary to life.
Oxygen: Element Name : Oxygen Symbol : O Presence in : 1. 70 kg Person : 43 kg 2. Body : 65 % 3. Earth Crust : 46 % 4. Earth Ocean : 86 % 5. Universe : 1 % Oxygen is important for human respiration. It is also used to kill bacteria that causes gangrene.
: C Presence in 70 kg Person : 16 kg Body : 23 % Earth Crust : 0.18 % Earth Ocean : 0.0028 % Universe : 0.5 % Carbon is used in formation of cytoskeleton, enzymes, hormones and regulation of physiology of body.
H Presence in 70 kg Person : 7 kg Body : 10 % Earth Crust : 0.15 % Earth Ocean : 11 % Universe : 75 % Hydrogen is used in the fixation of nitrogen from the air in the Haber ammonia process and for the hydrogenation of fats and oils.
N Presence in 70 kg Person : 1.8 kg Body : 3 % Earth Crust : 0.002 % Earth Ocean : 0.00005 % Universe : 0.1 % Your body needs the nitrogen in amino acids from protein foods to make other amino acids it uses to synthesize human proteins.
Ca Presence in 70 kg Person : 1.0 kg Body : 1.5 % Earth Crust : 5 % Earth Ocean : 0.00042 % Universe : 0.007 % Calcium is the most plentiful mineral found in the human body.
P Presence in 70 kg Person : 780 g Body : 1.1 % Earth Crust : 0.099 % Earth Ocean : 0.000007 % Universe : 0.0007 % Phosphorus is one mineral that performs a number of important functions. It combines with calcium to form a relatively insoluble compound calcium phosphate, which gives strength and rigidity to bones and teeth.
