  1. Electrolyte
    1. Body fluid substances that dissociate into anions and cations including Sodium, Potassium, Magnesium and calcium
    2. Electrolytes have broad functionality in human physiology including fluid hemeostasis and cellular function

III. Physiology

  1. Electrolyte homeostasis is a core function of the Kidney (esp. Sodium, water and acid-base)

Definition (NCI) Substances that ionize into anions and cations in body fluids. Electrolytes regulate nerve and muscle function and water distribution between cells, plasma, and interstitial fluid. Imbalances can cause serious physiologic effects, including seizures, cardiac arrhythmias and convulsions.
Definition (MSH) Substances that dissociate into two or more ions, to some extent, in water. Solutions of electrolytes thus conduct an electric current and can be decomposed by it (ELECTROLYSIS). (Grant & Hackh's Chemical Dictionary, 5th ed)
Definition (CSP) substance that while in solution or its pure state will conduct an electric current by means of the movement of ions; in physiology, usually refers to compounds such as sodium, potassium, magnesium and calcium which dissociate fluids into ions that conduct electric currents and that constitute the major force in controlling fluid balance within the body.
