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 ...
