_______ Acts on the Collecting Ducts and Causes an Increase

Question

_______ acts on the collecting ducts and causes an increase in water excretion by the kidneys.
A) Antidiuretic hormone (ADH)
B) ATP
C) Aldosterone
D) Angiotensin

Accepted Answer

Antidiuretic hormone (ADH), also known as vasopressin, acts on the collecting ducts of the kidneys to increase water reabsorption and decrease water excretion. Therefore, the opposite effect would occur in the absence of ADH, which would lead to an increase in water excretion.
