Multiple Choice

Which of the following statements about ADH (antidiuretic hormone) secretion is true?

ADH secretion increases when blood osmolarity decreases.

ADH secretion is stimulated by dehydration.

ADH is secreted by the anterior pituitary gland.

ADH decreases water reabsorption in the kidneys.

Verified step by step guidance

Understand the role of ADH (antidiuretic hormone) in the body: ADH is crucial for regulating water balance by controlling the amount of water reabsorbed by the kidneys.

Identify the conditions that stimulate ADH secretion: ADH is typically released in response to high blood osmolarity, which occurs during dehydration when the concentration of solutes in the blood is high.

Evaluate the statement about blood osmolarity: ADH secretion increases when blood osmolarity increases, not decreases. This is because the body needs to conserve water to dilute the solutes.

Clarify the source of ADH: ADH is produced by the hypothalamus and released by the posterior pituitary gland, not the anterior pituitary gland.

Assess the effect of ADH on the kidneys: ADH increases water reabsorption in the kidneys, helping to concentrate the urine and reduce water loss, which is the opposite of decreasing water reabsorption.
