Solución
The hormone that regulates blood sodium concentration by stimulating
conservation in the kidneys is Aldosterone.
Explanation:
-
Aldosterone is a mineralocorticoid hormone produced by the adrenal cortex. It plays a crucial role in regulating sodium and potassium levels in the blood. Aldosterone promotes the reabsorption of sodium (
) and the excretion of potassium ( ) in the distal tubules and collecting ducts of the nephron in the kidneys. This action helps maintain blood sodium balance and, consequently, blood pressure. -
Antidiuretic Hormone (ADH), also known as vasopressin, primarily regulates water balance in the body by increasing water reabsorption in the kidneys’ collecting ducts. While it indirectly affects sodium concentration by influencing water retention, its primary role is not the direct regulation of sodium ions.
-
Cortisol is a glucocorticoid hormone that has multiple functions, including glucose metabolism, immune response modulation, and stress response. While high levels of cortisol can influence electrolyte balance, it is not the primary hormone responsible for sodium conservation in the kidneys.

Extra Insights
Aldosterone is a crucial hormone produced by the adrenal cortex, and it plays a significant role in maintaining electrolyte balance. When sodium levels in the blood drop, aldosterone kicks into gear, signaling the kidneys to retain sodium and excrete potassium, effectively helping to regulate blood pressure and fluid balance. This process is essential for your overall health and can impact everything from athletic performance to how you feel every day!
Understanding the role of aldosterone can also help in real-world scenarios, especially for individuals with conditions like hypertension or heart disease. By managing sodium intake and medication that influences aldosterone levels, patients can better control their blood pressure and overall cardiovascular health. It’s a powerful reminder of how hormones affect our daily lives and health outcomes!
