Abstract
The kidney is an important determinant of endogenous Pi pools in the mammal. Pi is filtered with plasma water and the major fraction of the filtered load is then reabsorbed by the tubule; a variable remainder is excreted (1–3). Many endogenous factors including PTH, Ca2+ and pH influence the process of net reabsorption, or reclamation, and it is now apparent that transepithelial transport of Pi in mammalian kidney is more complex than was anticipated from the classic observations of Pi reclamation (4, 5). Accordingly, we will consider the phenomenon of transepithelial transport which underlies net reabsorption, and the evidence for heterogeneity between nephrons, and within nephrons, in the response to regulatory events which influence Pi transport.
