In the human kidney, the part of nephron where receptors for antidiuretic hormone (ADH) are found is
Correct answer: D. Collecting duct
- A. Glomerulus
- B. Ascending loop of Henle
- C. Descending loop of Henle
- D. Collecting duct
Explanation
The correct answer is the collecting duct. The collecting duct is where the receptors for antidiuretic hormone (ADH) are located. ADH binds to these receptors to increase water reabsorption, thus concentrating the urine. The glomerulus, ascending loop of Henle, and descending loop of Henle do not have ADH receptors; they play different roles in the filtration and reabsorption processes within the nephron.

About Kidney and Urinary System
The kidney and urinary system remove nitrogenous wastes, regulate water and ion balance, and help maintain blood pH through filtration, selective reabsorption and secretion. Questions cover nephron structure, ultrafiltration, the loop of Henle, collecting ducts, urine formation and the roles of ADH and aldosterone, while distinguishing excretion from egestion.
