Mineral homeostasis (storage and release): bone is important site of calcium storage: calcium level becomes too low & decreasing. Body starts to break down bone tissue & release that storage calcium. Brings calcium lv back to normal: calcium level becomes too high. Body starts to lay down bones to pull up that ca down and bring it back to normal.
