WebRelationship between parathyroid hormone (PTH) and calcitonin (CT) secretion and ionized calcium concentration. PTH and CT secretion are normalized to percent of maximum. The dashed line shows half-maximal secretion, which occurs at ∼1.2 mM Ca 2+. This is referred to as the set point. PTH secretion increases to defend calcium homeostasis. Calcitonin is a hormone that your thyroid gland makes and releases to help regulate calcium levels in your blood by decreasing it.
