'''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.
