The pathway that assures the proper transport of phosphate in the body. The kidney plays a major role in the filtration and reabsorption of phosphate while bone is a principal form of storage. Several types of sodium phosphate cotransporters are involved; the role of type 2 and 3 has been established. Renal phosphate transport is under the control of parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF23) signaling.
