AThe proximal convoluted tubule
BThe descending loop of Henle
CThe collecting ducts and tubules
DThe glomerulus and its capsule
Answer & Solution
Correct answer: C. The collecting ducts and tubules
1. Antidiuretic hormone, also called vasopressin, is made in the hypothalamus.
2. It is stored and released by the posterior pituitary gland into the blood.
3. Its renal target is the collecting ducts and tubules, where water is recovered.
4. The glomerulus filters plasma but is not where this hormone acts.
