Question

Which of the following statements are correct?

1. An excessive loss of body fluid from the body switches off osmoreceptors.
2. ADH facilitates water reabsorption to prevent diuresis.
3. ANF causes vasodilation.
4. ADH causes increase in blood pressure.
5. ADH is responsible for decrease in GFR.

Choose the correct answer from the options given below:

Options

• B, C and D only

• A, B and E only

• C, D and E only

• A and B only

Answer 1

B, C and D only

Explanation:

ADH prevents water loss (diuresis) by helping the kidneys reabsorb fluid. In contrast, Atrial Natriuretic Factor (ANF) acts as a vasodilator, widening blood vessels to lower blood pressure. While ADH focuses on maintaining fluid balance through the kidneys, this regulation indirectly helps stabilize blood pressure.
