Calcium Metabolism

Meaning

Calcium Metabolism is the complex, tightly regulated physiological process that governs the absorption, distribution, mobilization, and excretion of calcium ions to maintain their concentration within a narrow, non-negotiable range in the extracellular fluid. This process is essential because calcium is critical for bone mineralization, neuromuscular transmission, blood clotting, and cellular signaling. The constancy of calcium homeostasis is paramount for life, with deviations leading to severe complications like tetany or pathological calcification.
