                                Over 99% of the body's total calcium is stored in bone, forming a vital reservoir that provides both structural integrity and a source of ions for biological processes. Understanding what stores and releases calcium ions is crucial for comprehending fundamental cellular functions like muscle contraction, nerve signaling, and hormone regulation.
