*Potassium is on the whole excreted from the '''principal cells of the collecting duct
*Potassium is on the whole excreted from the '''principal cells of the collecting duct
**This occurs via the paracellular route and via ion channels
**This occurs via the paracellular route and via ion channels
** The gradient for the loss via the ion channels is maintained by the sodium/pottasium ATPase in the basolateral membrane
