Renin from JG cell via switching off the osmoreceptors
ANF from atria of the heart
Aldosterone from adrenal medulla
Vasopressin from Neurohypophysis
Solution
The correct answer is option (4) because,
- Diuresis is prevented by vasopressin or anti-diuretic hormone from neurohypophysis or posterior pituitary. When there is excessive loss of fluid from the body the secretion of, ADH facilitates water reabsorption from latter part of renal tubules.
- Option (1) is incorrect because renin from JG cells convert angiotensinogen in blood to angiotensin I and further to angiotensin II; which is a powerful vasoconstrictor and increases the glomerular blood pressure and thereby GFR.
- Option (2) is incorrect because ANF causes vasodilation and thereby decrease GFR.
- Option (3) is incorrect because aldosterone is released from adrenal cortex and causes reabsorption of $\mathrm{Na}^{+}$and water from distal parts of renal tubules.
