Web10.2.1 Role of the kidney in phosphate homeostasis. In states of neutral phosphate balance, the amount of phosphate excreted in the urine is equal to the net amount of intestinal phosphate absorption. Virtually, all inorganic phosphate in the serum is filtered by the glomerulus [35–37]. About 80%–90% of filtered phosphorus is reabsorbed in ...

WebPhosphate homeostasis is maintained by a counterbalance between efflux from the kidney and influx from intestine and bone. FGF23 is a bone-derived phosphaturic hormone that acts on the kidney to increase phosphate excretion and suppress biosynthesis of 1,25 (OH) 2 D 3. WebNormal serum phosphorus is defined as serum phosphorus levels between 2.5 and 4.5 mg/dl (0.81-1.45 mmol/L). Phosphorus homeostasis is a complex interplay between several organs and hormones.

WebSep 10, 2024 · Physiologically, the maintenance of calcium and phosphorus homeostasis is achieved via a variety of concerted actions of hormones such as parathyroid hormone (PTH), vitamin D, and fibroblast growth factor (FGF23), which could be regulated mainly at three organs, the intestine, kidney, and bone.
WebAug 8, 2024 · When phosphate intake was excessive relative to the number of functioning nephrons, circulating levels of FGF23, a hormone that increases the excretion of phosphate per nephron, were increased to maintain phosphate homeostasis. FGF23 suppressed phosphate reabsorption in renal tubules and thus raised the phosphate concentration in …
