Final answer:

Aldosterone plays a crucial role in maintaining electrolyte balance by responding to changes in blood sodium, potassium levels, and volume/pressure.


Explanation:

Aldosterone is a hormone released from the adrenal cortex in response to a decrease in blood sodium levels, an increase in blood potassium levels, or alterations in blood volume or pressure. This hormone helps regulate the balance of ions in urine, sweat, and saliva. For example, aldosterone promotes sodium reabsorption and water retention while facilitating potassium excretion.
