This term is quite hard to memorise as there is not much chance to use it. It is a mineral that makes up 1% of a person's total body weight. It is present in every cell of the body, but most of the phosphorus in the body is found in the bones and teeth. Phosphorus works with the B vitamins. It also assists in the contraction of muscles, in the functioning of kidneys, in maintaining the regularity of the heartbeat, and in nerve conduction.
The main food sources are the protein food groups of meat and milk. A meal plan that provides adequate amounts of calcium and protein also provides an adequate amount of phosphorus. Although whole-grain breads and cereals contain more phosphorus than cereals and breads made from refined flour, this is a storage form of phosphorus called phytin, which is not absorbed by humans. Fruits and vegetables contain only small amounts of phosphorus.
And phosphorous ignites at a much lower temperature than other material, approximately 30 degrees, phosphorous what was melted from the corps buried on the cemetery seldom formed a blue round flame that floats on the tombs and was regarded as ghost or spirit in old days.
