Transcript text: Question 10
Antidiuretic hormone (ADH) $\qquad$
(A) increases urine production
(B) promotes dehydration
(C) is produced by the anterior pituitary
(D) secretion is inhibited by alcohol
Solution
The answer is (D): secretion is inhibited by alcohol.
Explanation for each option:
(A) Increases urine production - This is incorrect. Antidiuretic hormone (ADH) actually decreases urine production by promoting water reabsorption in the kidneys, which concentrates the urine and reduces its volume.
(B) Promotes dehydration - This is incorrect. ADH helps prevent dehydration by conserving water in the body. It does this by increasing water reabsorption in the kidneys, thus reducing water loss through urine.
(C) Is produced by the anterior pituitary - This is incorrect. ADH is produced by the hypothalamus and stored and released by the posterior pituitary gland, not the anterior pituitary.
(D) Secretion is inhibited by alcohol - This is correct. Alcohol inhibits the secretion of ADH, which leads to increased urine production and can contribute to dehydration.
In summary, the correct answer is (D): secretion is inhibited by alcohol.
