Question

If ADH secretion is inhibited, which of the following would initially result?

a) The person would produce greater amounts of dilute urine.
b) The number of aquaporins would increase in response to the inhibition of ADH.
c) The person would decrease oral water intake to compensate for the inhibition of ADH.
d) Blood filtration would increase to compensate for the lack of aquaporins.

Answer 1

When ADH secretion is inhibited, the person would produce greater amounts of dilute urine.

Step-by-step explanation:

When ADH secretion is inhibited, the number of aquaporin channels inserted into the apical membrane of principal cells in the kidney collecting ducts decreases. This leads to a decrease in water reabsorption and the production of greater amounts of dilute urine. So, the correct answer is a) The person would produce greater amounts of dilute urine.
