Summary Introduction

To review:

The major regulatory hormone of Ca⁺² in blood, and the effects of hypercalcemia and hypocalcemia.

Introduction:

Ca⁺² is an important ion in body fluids, which is mainly found in bones. It is present in the form of calcium phosphate and provides strength to the skeleton system. Balance of plasma Ca⁺² is important for several processes, such as blood clotting, cell membrane permeability, and secretion of contents from vesicles. Hypocalcemia and hypercalcemia are homeostatic imbalances that are lifethreatening.
