Calcium is the fifth element and the third-most abundant metal in the Earth’s crust. The distribution of calcium is very wide. In fact, it is found in almost every terrestrial area in the world. It is not found alone in nature, but it occurs abundantly as limestone, gypsum, fluorite and apatite. This element is essential for the life of plants and animals. In fact, it is present in the animal’s skeleton, in teeth, in the egg’s shell, in the coral and in many soils. It is also contained in the soft tissue, in fluids within the tissue and in the structure of every animal’s skeleton.
