Hormonal coordination in humans

Question

A. To regulate body temperature
B. To prevent dehydration and maintain cell function
C. To control blood pressure only
D. To enhance muscle performance

Answer

The correct option is To prevent dehydration and maintain cell function. This answer is correct because it matches the approved learning objective to explain (HT only) how ADH release is controlled by negative feedback to maintain blood water concentration in the subtopic Maintaining water and nitrogen balance in the body (biology only).

Explanation

The correct option is To prevent dehydration and maintain cell function. To prevent dehydration and maintain cell function is correct because it directly supports the approved learning objective to explain (HT only) how ADH release is controlled by negative feedback to maintain blood water concentration. This belongs to the subtopic Maintaining water and nitrogen balance in the body (biology only) within Hormonal coordination in humans, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Maintaining water and nitrogen balance in the body (biology only).

Common mistake

Misunderstanding ADH Function

Students often confuse the role of ADH with other hormones, thinking it directly increases blood water concentration rather than controlling its release through negative feedback.

Clarify that ADH regulates water reabsorption in the kidneys and that its release is controlled by negative feedback mechanisms that respond to blood water concentration levels.
