Calcium Phosphorus Homeostasis
The integrated physiological system that maintains optimal blood levels of calcium and phosphorus through hormonal and renal interactions.
Key Facts
- Parathyroid hormone, calcitriol, and fibroblast growth factor 23 coordinate to regulate mineral balance.
- Bone tissue serves as a dynamic storage reservoir that releases or absorbs calcium based on systemic demand.
- The kidneys act as the primary excretory pathway, adjusting phosphorus retention based on hormonal signals.
- Disruption of this balance rapidly leads to systemic complications affecting musculoskeletal and cardiovascular health.
