Physiology of Potassium Handling. Potassium (K+) is the most abundant cation in the body. About 90% of total body potassium is intracellular and 10% is in extracellular fluid, of which less than 1% is composed of plasma.
Concentrations of intracellular and extracellular cations are as follows: 1  Intracellular potassium concentration averages 140 mEq/L. 2  Extracellular potassium concentration is 3.5 to 5 mEq/L. 3  Intracellular sodium concentration is 12 mEq/ 4 L. Extracellular sodium concentration averages 140 mEq/ L.
