Lesson 44 : Bioavailability and Ion Absorption Electrolyte Balance
Electrolytes are the chemicals dissolved in the body fluid. Sodium and potassium are two of the electrolytes essential for proper body function. Several foods that we eat provide these electrolytes, but often they are not in the correct proportion. Sodium chloride is found mostly in extracellular fluid, while potassium and phosphate are the main ions in the intracellular fluid.
