Detailed Solution

B, C and D are correct. A and E are incorrect.

A. An excessive loss of body fluid from the body switches on osmoreceptors. This leads to the relsease of ADH.

B. ADH facilitates water reabsorption from ADH and CD to prevent diuresis.

C. ANF is released in response to increased blood volume and stretching of the atria. ANF causes vasodilation leading
to a decreased blood pressure.

D. By promoting water reabsorption from DCT and CD, ADH helps to retain water in the body, leading to an increase in blood volume. The increased blood volume, in turn, can raise blood pressure.

E. ADH is responsible for an increase in GFR. ADH (vasopressin) can affect the kidney function by its stimulating the
constriction of arteries. This increases blood pressure, leading to an increase in GFR.
