Question

During the activation of the stress response, there is an increased secretion of aldosterone. Which finding is not an effect you will see with the release of this hormone?

1- Water retention
2- Potassium excretion
3- Calcium excretion
4- Sodium retention

Answer 1

Among the listed options, calcium excretion is not an effect of increased aldosterone secretion, as aldosterone primarily influences sodium reabsorption, potassium excretion, and water retention.

Step-by-step explanation:

When considering the effects of the aldosterone hormone during the stress response, there are several consequences including sodium retention, water retention, and potassium excretion. Of the given options, the one that is not an effect seen with the release of aldosterone is calcium excretion. Aldosterone's primary functions include the reabsorption of sodium ions (Na+) from kidney tubules, which promotes water retention and increases blood pressure. Additionally, it regulates potassium ions (K+) by promoting their excretion. However, aldosterone does not directly trigger the excretion of calcium ions (Ca2+). This is reflected in the lack of an increase in calcium excretion when aldosterone levels are elevated.
