Calcium homeostasis

Abstract

This review deals with calcium homeostasis, the calciotropic hormones and the effector organs. The extracellular calcium concentration is influenced by gains or losses of calcium via the bone remodelling system, the kidney and the gut. These fluxes are all influenced by hormones (parathyroid hormone, 1,25-dihydroxy vitamin D and calcitonin) whose secretion is partly governed by the plasma calcium level.
