Verified step by step guidance

Understand the role of adrenal hormones: The adrenal glands produce several hormones, including norepinephrine, epinephrine, cortisol, and aldosterone, each with distinct functions.

Identify the function of aldosterone: Aldosterone is a mineralocorticoid hormone that helps regulate sodium and potassium levels in the blood. It is secreted by the adrenal cortex in response to low blood sodium levels.

Consider the physiological response to low sodium: When blood sodium levels drop, the body needs to retain sodium to maintain electrolyte balance and blood pressure. Aldosterone acts on the kidneys to increase sodium reabsorption.

Differentiate between the hormones: Norepinephrine and epinephrine are catecholamines involved in the 'fight or flight' response, not directly related to sodium regulation. Cortisol is a glucocorticoid involved in stress response and metabolism, not specifically in sodium regulation.

Conclude the correct hormone response: Based on the function of aldosterone in sodium regulation, it is the hormone secreted in response to a drop in blood sodium content.
