Calcium homeostasis refers to the regulation of the concentration of calcium ions in the extracellular fluid [Ca++]ECF.This parameter is tightly controlled because the calcium ions have a stabilizing effect on voltage-gated ion channels.alcium homeostasis refers to the regulation of the concentration of calcium ions in the extracellular fluid [Ca++]ECF.
The hormones parathyroid hormone (PTH) and calcitonin help regulate blood calcium levels. Calcitonin, secreted by the thyroid gland inhibits osteoclasts and stimulates osteoblasts, thus decreasing blood calcium levels. Parathyroid hormone is secreted by the parathyroid glands, which are on the posterior side of the thyroid. Parathyroid hormone inhibits osteoblasts, stimulates osteoclasts, reduces the output of calcium by the kidneys and promotes the absorption of calcium by the small intestines, thus increasing blood calcium levels.
