'''Calcium''' is a very important element to human [[physiology]], as calcium-[[phosphate]] salts form the basis for the creation of [[bones]]. It is also a critical cellular component in all organisms, and in animals serves roles of particular importance in blood, the [[cardiovascular system]], and the [[nervous system]]. Consuming too much calcium can lead to [[kidney stone]]s, which are typically composed of calcium deposits.

Calcium in its pure form is referred to as "the white element" and is kept sealed in underground chambers due to the hazards involved in its handling.

Calcium in its pure form is referred to as "the white element" and must be kept isolated from air.
