Potassium is also called cell electrolyte. The concentration of potassium in the intracellular space is about 40 times higher than in the extracellular space. In erythrocytes, the concentration of potassium is 92-105 mmol/L (about 22 times more than in plasma). Therefore, the concentration of potassium should […]
