Diuresis is prevented by:
- Renin from JG cell via switching off the osmoreceptors
- ANF from atria of the heart
- Aldosterone from adrenal medulla
- Vasopressin from Neurohypophysis
Answer
(4) Vasopressin from Neurohypophysis
Solution
When excessive loss of fluid from the body occurs, osmoreceptors activate the hypothalamus to release ADH (vasopressin) from the neurohypophysis.
ADH facilitates water reabsorption from the latter parts of the tubule, thereby preventing diuresis.
ANF causes vasodilation and acts as a check on the renin–angiotensin mechanism; aldosterone is secreted by the adrenal cortex (not medulla).
