Aldosterone is the most potent mineralocorticoid produced in the adrenal cortex and is produced when there is rise in blood potassium and BP. True / False.

Answer: False

Explanation:

Aldosterone is the main mineralocorticoid, acting in the regulation of electrolyte homeostasis in extracellular fluid, mainly sodium (Na) and potassium (K). Exerts its effect on distal and distorted Nephron tubules collecting duct. Aldosterone production is under the control of serum renin, angiotensin and K levels. Because of its relation with potassium levels, it is released in response to elevated blood K+, resulting in an increase in Na + reabsorption and K excretion, leading to an increase in water reabsorption. It is also related to low blood pressure. With the consequent increase in water reabsorption, we have an increase in blood volume and cardiac output, leading to an increase in blood pressure.
