Clinical Significance
Sodium (Na) is the primary extracellular cation. Sodium is responsible for almost one half the osmolality of the plasma and, therefore, plays a central role in maintaining the normal distribution of water and the osmotic pressure in the extracellular fluid compartment. The amount of Na in the body is a reflection of the balance between Na intake and output. The body requires only 1-2 mmol/day, and the excess is excreted by the kidneys, which are the ultimate regulators of the amount of Na (and thus water) in the body.
