Which hormone causes an increase in permeability to water in the collecting ducts of the kidney? A. antidiuretic hormone B. aldosterone C. angiotensin II D. atrial natriuretic hormone
Option A. Antidiuretic hormone causes an increase in permeability to water in the collecting duct. If the collecting ducts are permeable to water, greater water may be reclaimed from the filterate. This will lower its quantity and there will be much less diuresis. Hence anti-diuretic hormone.
