In man, over the normal dietary intake, inorganic phosphate (Pi) absorbed from the gut is a linear function of Pi intake1. Pi absorption measured in man by the intubation-perfusion technique shows that at low Pi concentrations, Pi absorbed rises steeply with increasing Pi perfused; at increasing concentrations Pi absorption falls but never saturates1. According to these data it has been suggested that Pi absorption consists of two processes: the first, a saturable,carrier mediated, active transport and the second a linear concentration-dependent diffusion process.
