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.
This test measures the main electrolytes in your body: sodium, chloride, potassium, and carbon dioxide. The cells in your body carefully balance fluids and electrolytes, which are electrically charged minerals.Electrolytes move fluid in and out of your cells.They carry nutrients into the cells and waste products back out. Electrolytes also help keep your water level normal and your pH level stable.he cells in your body carefully balance fluids and electrolytes, which are electrically charged minerals.
