Correct Answer is C
Explanation
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.

D. Inspiratory reserve volume: This is included in the calculation of vital capacity.
