Multiple Choice

Which of the following statements is true regarding aldosterone?

Aldosterone is responsible for the regulation of calcium levels in the blood.

Aldosterone is produced by the adrenal cortex and helps regulate sodium and potassium levels.

Aldosterone is secreted by the pituitary gland and is involved in the fight-or-flight response.

Aldosterone is a hormone that primarily targets the pancreas to regulate blood sugar levels.

Verified step by step guidance

Begin by identifying the primary function of aldosterone. Aldosterone is a hormone that plays a crucial role in regulating electrolyte balance, specifically sodium and potassium levels in the blood.

Understand the source of aldosterone production. Aldosterone is produced by the adrenal cortex, which is part of the adrenal glands located on top of the kidneys.

Differentiate aldosterone from other hormones. Unlike hormones involved in calcium regulation (such as parathyroid hormone) or those secreted by the pituitary gland (like ACTH), aldosterone specifically targets the kidneys to influence sodium and potassium balance.

Recognize the physiological effects of aldosterone. It acts on the distal tubules and collecting ducts of the nephron in the kidneys, promoting sodium reabsorption and potassium excretion, which helps maintain blood pressure and fluid balance.

Clarify misconceptions about aldosterone's role. Aldosterone does not regulate calcium levels, is not secreted by the pituitary gland, and does not target the pancreas for blood sugar regulation. Its primary function is related to sodium and potassium balance.
