Antidiuretic hormone (ADH) affects the functioning of human nephron If ADH is secreted in low quantity, then it affects the
Correct answer: A. reabsorption of water in collecting duct.
- A. reabsorption of water in collecting duct.
- B. removal of hydrogen ions from peritubular capillaries.
- C. removal of water from ascending limb of loop of Henle
- D. reabsorption of sodium ions in the proximal convoluted tubule
Explanation
ADH affects reabsorption of water in collecting duct. Normally it increases the water reabsorption in collecting duct concentrating the urine. So option A is correct,. ADH has no role in the processes given in other options. So B,C and D are incorrect.

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.
