Question

When fluid intake is HIGH, ADH is NOT secreted, resulting in:
Options
A More concentrated urine and less urine output
B Less reabsorption — increased and more dilute urine output
Correct Answer
C Decreased glomerular filtration
D More ADH released by the kidney
Correct Answer

Option B is the correct answer.

Detailed Explanation

When fluid intake is high, ADH is not secreted, resulting in less water reabsorption. This produces increased urine output that is relatively dilute, eliminating excess water from the body.

Hint

Without this hormone, the collecting ducts become impermeable to water, producing large volumes of dilute urine.
