The most important regulator of electrolyte concentrations in extracellular fluids is . A. cortisol B. aldosterone C. glucagon D. insulin

The correct option is B. aldosterone

Explanation:

In organisms the most important electrolytes from the point of view of their concentration, therefore, of their osmotic effect, are the sodium and potassium ions. Aldosterone is a hormone produced by the adrenal glands, it helps to control blood pressure and it maintains healthy levels of sodium and potassium in the blood, preserving the balance of body fluids and allowing nerves and muscles to function well. The renin hormone, produced by the kidneys, normally stimulates the adrenal glands to release aldosterone.
