/Ortho/ phosphate is absorbed from, and to a limited extent secreted into, the gastrointestinal tract. The transport of phosphate from the lumen of the gut is an active, energy-dependent process, and there are factors that appear to modify the degree of its intestinal absorption. ... Vitamin D stimulates phosphate absorption, and this effect has been reported to precede the action of the vitamin on transport of calcium ion. In general, in adults, about two thirds of the ingested phosphate is absorbed from the bowel, and that which is absorbed from the gut is almost entirely excreted into the urine. In growing children, there is a positive balance of phosphate. Concentrations of phosphate in plasma are higher in children than in adults. This "hyperphosphatemia" decreases the affinity of hemoglobin for oxygen and is hypothesized to explain the physiological "anemia" of childhood. /Phosphates/
