The third largest city in Morocco also boasts one of the most magnificent sights: tanneries in midst of an old medina. Hailed as a UNESCO World Heritage Site, Fez has made a name for itself as a must-go destination for numerous travelers.
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.
As with calcium, the majority of body phosphate (approximately 85%) is present in the mineral phase of bone. The remainder of body phosphate is present in a variety of inorganic and organic compounds distributed within both intracellular and extracellular compartments. Stimulating net resorption of bone mineral releases calcium and phosphate into blood, and suppressing this effect allows calcium to be deposited in bone. 2  The kidney is critcally important in calcium homeostasis.
