Calcium and Phosphate Homeostasis Endotext NCBI Bookshelf

Jan 19, 2018· Calcium and phosphate are critical to human physiology (e.g. neuromuscular function) and are also needed for skeletal mineralization. An understanding of calcium and phosphate metabolism is required for the clinician to evaluate disorders of the levels of calcium and phosphorus as well as metabolic skeletal disorders.

Calcium and Phosphate Homeostasis

Facilitates mobilization of calcium and phosphate from bone. To prevent detrimental increases in phosphate, parathyroid hormone also has a potent effect on the kidney to eliminate phosphate (phosphaturic effect). Maximizes tubular reabsorption of calcium within the kidney. This activity results in minimal losses of calcium in urine.

Jun 03, 2015· Hormonal regulation of calcium metabolism is summarized in Figure 17-1. Calcium and phosphorus are absorbed in the small intestine under the influence of 1,25-dihydroxyvitamin D (1,25-[OH] 2 D), which stimulates calcium-binding protein carriers. PTH mobilizes calcium and phosphorus in bone by stimulating osteolysis.

Jun 11, 2016· Therefore, it is not surprising that, like calcium, phosphate metabolism is closely regulated. Total body phosphorus is 500–800 g (16.1–25.8 moles), 85–90% of which is in the skeleton. Total plasma phosphorus is about 12 mg/dL, with two-thirds of this total in organic compounds and the remaining inorganic phosphorus (P i ) mostly in PO 4
