Question

Identify the correct statement regarding urine formation

• A. Counter current mechanism works around the glomerulus and PCT
• B. To prevent diuresis, ADH facilitates water reabsorption from the latter parts of the tubule
• C. Maximum absorption of electrolytes occurs in the Henle’s loop
• D. A decrease in blood pressure can increase the glomerular filtration rate
• E. The collecting duct is impermeable to water and thus helps in diluting the urine

Answer 1

Answer: (B)

ADH is antidiuretic hormone or vasopressin or pitressin. It increases the reabsorption of water in the distal convoluted tubule and collecting ducts of the nephrons of kidney. As a result, water reabsorption from glomerular filtrate is increased and urine becomes concentrated
