The major division is between the intracellular and extracellular portions: Hence, if the sodium concentration goes up in your extracellular fluid, water will tend to leave your cells and move to make up the difference there.odium and Water (1) - Body compartments. The human body is approximately 50-60% water (on the higher end for men, on the lower end for women). This water is distributed in two major compartments-the intracellular fluid compartment and the extracellular fluid compartment, in a ratio of roughly 2:1.
It differs from intracellular fluid (fluid within the cells) in that it generally has a high concentration of sodium and low concentration of potassium, while intracellular fluid is high in potassium and low in sodium. The fluid is often secreted by cells to provide a constant environment for cellular operations.
