The remaining calcium is in the extracellular fluid and in various tissues, where it regulates numerous processes, including vascular tone, muscle contraction-dilation, nerve impulse transmission, intracellular signaling, ATP production, and hormonal secretion.

The physiological concentration of calcium in the blood is tightly regulated (Table 1) within a range of 8.8–10.4 mg/dL by parathyroid hormone (parathormone, PTH), 1,25-dihydroxyvitamin D3 (active metabolite of vitamin D), and calcitonin (CT).
