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.
An increase in extracellular potassium concentration also stimulates aldosterone secretion (via angiotensin II), and aldosterone increases K+ excretion. In the steady state, K+ excretion matches intake, and approximately 90% is excreted by the kidneys and 10% in the stool.
