The human body consists of six main elements, namely—
(i) Oxygen (ii) Carbon (iii) Hydrogen
(iv) Nitrogen (v) Calcium (vi) Phosphorus
Apart from these, elements like potassium, sodium, chlorine, magnesium, and sulphur are also present in tiny quantities in the body.
All of the above-mentioned elements are extremely vital for the proper functioning of our bodies. Let us have a detailed look at the elements—
|Name of the element||Quantity (in percentage)||Name of the element||Quantity (in percentage)|
|(i) Oxygen||65%||(vii) Potassium||0.4%|
|(ii) Carbon||18.5%||(viii) Sulphur||0.3%|
|(iii) Hydrogen||9.5%||(ix) Sodium||0.2%|
|(iv) Nitrogen||3.3%||(x) Chlorine||0.2%|
|(v) Calcium||1.5%||(xi) Magnesium||0.1%|
Functions of the main elements:
Calcification-A process in which calcium builds up in the body tissues and helps in the formation of bones.
Synthesis-Formation of a substance by the combination of different things.
