The secretion of which hormone increases the permeability of cells in the collecting ducts to water so more can be reabsorbed?
Aldosterone hormone
Atrial natriuretic peptide hormone
Antidiuretic hormone
Parathyroid hormone
The Correct Answer is C
A. Aldosterone hormone: Aldosterone affects sodium and potassium reabsorption, increasing water retention indirectly, but it does not directly increase water permeability in the collecting ducts.
B. Atrial natriuretic peptide hormone: This hormone decreases blood volume by inhibiting sodium reabsorption, leading to more water excretion, not reabsorption.
C. Antidiuretic hormone (ADH): ADH increases the permeability of the collecting ducts to water, allowing more water to be reabsorbed into the bloodstream.
D. Parathyroid hormone: This hormone primarily regulates calcium levels, not water permeability.
