calcium

Definition

A chemical element with the symbol Ca, it is a soft silvery alkaline earth metal. It is essential for living organisms in particular in cell physiology, where movement of calcium ions into and out of the cells functions as a signal for many cellular processes. As a major material used in the mineralisation of bones, calcium is the most abundant metal by mass in many animals.
