1 Sodium plays a large role in fluid balance, with different variations of sodium determining the shift of water by osmosis from one area of the body to another.  Along with chloride and bicarbonate, sodium is important for the proper regulation of the acid-base balance of the body.
Salt (sodium chloride) is essential for life. The tight regulation of the body's sodium and chloride concentrations is so important that multiple mechanisms work in concert to control them.odium (Na +) and chloride (Cl -) are the principal ions in the fluid outside of cells (extracellular fluid), which includes blood plasma. As such, they play critical roles in a number of life-sustaining processes (2) .
