WebChloride functions to balance cations in the ECF, maintaining the electrical neutrality of this fluid. The paths of secretion and reabsorption of chloride ions in the renal system follow the paths of sodium ions. Hypochloremia, or lower-than-normal blood chloride levels, can occur because of defective renal tubular absorption. WebK + ions have essential role in maintaining cellular resting membrane potentials and in generating functional activity in muscle cells, neurons, and cardiac tissue. • Overall, intracellular K + concentration is ∼30 times greater than extracellular K + concentration; this ratio is maintained by cell membrane Na + / K + ATPase. • darlene michaud mother
