ADH Exerts Its Effects Primarily on The

Question

ADH exerts its effects primarily on the
A) proximal convoluted tubule.
B) afferent arteriole.
C) collecting duct.
D) renal pelvis.

Accepted Answer

ADH, also known as vasopressin, primarily acts on the collecting ducts in the kidneys, increasing their permeability to water and promoting reabsorption of water into the bloodstream. This results in the production of more concentrated urine and helps maintain fluid balance in the body. ADH does not directly affect the proximal convoluted tubule, afferent arteriole, or renal pelvis.
