Which Section of the Nephron is Sensitive to Antidiuretic Hormone

Question

Which section of the nephron is sensitive to antidiuretic hormone?
A) distal convoluted tubule
B) nephron loop
C) collecting duct
D) proximal convoluted tubule

Accepted Answer

The collecting duct is sensitive to antidiuretic hormone (ADH), also known as vasopressin. ADH increases the water permeability of the collecting duct, allowing for reabsorption of water and concentration of urine. The distal convoluted tubule and proximal convoluted tubule are not directly affected by ADH. The nephron loop is involved in countercurrent multiplication, which helps create a concentration gradient in the medulla of the kidney, but it is not directly affected by ADH.
