* Here the potassium and chloride symporter actually excretes the two ions into the lumen of the tubule

* Na<sup>+</sup> / K<sup>+</sup> ATPases in the basolateral membrane move potassium into epithelial cells from the intercellular spaces in order to remove sodium. The potassium then diffuses into the lumen via channels
