PY - 2017 T2 - CURRENT Diagnosis & Treatment: Nephrology & Hypertension, 2e AB - Approximately 80–85% of phosphorus in the body is contained in bone, 14% in cells and soft tissues, and 1% in the extracellular fluid. A very small fraction of the intracellular pool is inorganic and available for synthesis of high-energy phosphorus-containing molecules. Neutral phosphate balance is maintained with dietary intakes over a wide range from 800 to 1500 mg/day. Phosphorus homeostasis is dependent upon the interaction of three organ systems: the gastrointestinal (GI) tract, bone, and kidney. A general overview of phosphorus metabolism is shown in Figure 7–1.
