WebRecall that the Na-K ATPase moves 3 Na+ ions for 2 K+ ions. As Na+ is reabsorbed, a charge potential is established across these epithelial cells such that the luminal surface membrane is more negative than the basal surface facing the blood. This charge gradient is used to move Cl- in a paracellular manner from filtrate to blood and to ...

WebDecreased Na+,K+-pump activity can result in a rise in intracellular Na+ concentrations which in turn increase Na+/Ca2+ exchange, thereby raising intracellular Ca2+ levels. In cardiac and skeletal muscle, this could interfere with normal contractile activity. Similarly, in vascular smooth muscle the result would be resistance to vasodilation.
