Electrolytes

Pronunciation (i-lek-truh-lahyt)

Minerals in your blood and other body fluids that carry an electric charge. It is important for the balance of electrolytes in your body to be maintained, because they affect the amount of water in your body, blood pH, muscle action, and other important processes. Electrolytes exist in the blood as acids, bases, and salts (such as sodium, calcium, potassium, chlorine, magnesium, and bicarbonate) and can be measured by laboratory studies of the blood serum.
