What functions do the electrolytes do in the body (Part 3.) ?😤

Finally, here is the last part about the electrolutes. 

Chlorine

Cl^- is one of the most important anions in the extracellular fluid, which can regulating the osmotic pressure and acid-base balance of the cell body.

Chlorine is mainly came from sodium chloride in the food. Therefore, the change of chlorine in the body is basically equaled to the sodium. However, there is an opposite relationship between the level of chlorine and the level of bicarbonate. It is because the anions in the body also need to be maintained at a certain concentration. As the two most important anions in the body, chlorine and bicarbonate are normally keeping at a balance way.

Normal serum Cl^- is 96-108 mmol/L. Increased serum Cl^- is common in hypernatremia and high chlorine metabolic acidosis.

In clinical, decreased serum Cl^- is more common and its cause is insufficient intake or increased loss of sodium chloride.
