The three primary function are to provide the “structural support, the storage of minerals and lipids, and the protections”. The skeletal system gives a basic support to the whole body. Individual bones or groups of bones give a structure to the connection of soft tissues and organs. The minerals are inorganic ions that add to the osmotic concertation of body fluid. Minerals additionally take part in different physiological procedures, and a few are imperative as enzyme cofactors. In the human body, the calcium is the most copious minerals. The calcium salts of bone are a significant mineral hold that keeps up the normal concentration of calcium and phosphate ions in the body fluid. Furthermore, the bones of the skeleton store energy as lipids
