explain the role of bone in calcium homeostasis
Calcium Homeostasis. 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.he role of PTH is to stimulate the regulated kidney enzyme, resulting in the production of 1,25(OH) 2 D. This is extremely important for bone health and Ca ++ homeostasis because 1,25(OH) 2 D works in the small intestine to promote Ca++ absorption.
