Major Electrolytes Located Outside the Cell (Extracellular) Sodium and Calcium Sodium is a major electrolyte in extracellular fluid and it exercises most of its influence outside the cell. The concentration of sodium affects serum osmolality (solute concentration in 1 L of water) and extracellular fluid volume. Sodium also assists nerves and muscle cells to interact.
Electrolytes exist in the form of calcium, chlorine, magnesium, phosphate, potassium, and sodium that can be obtained from fluids, supplements, and foods. For example, bananas are excellent sources of potassium. The balance of electrolytes is constantly shifting due to fluctuating fluid levels in your body. For example, when you sweat as a result of exercise, hot weather, or illness, some electrolyte levels may be low. Vomiting and diarrhea are other causes of electrolyte imbalances, as they result in excessive fluid loss. You must replenish these fluids and electrolytes in order to prevent dehydration, a potentially life-threatening condition.
