Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When you drink a larger volume of water than is required by your body tissues:
A
ADH secretion will be increased
B
ADH secretion will be inhibited
C
ADH secretion will not be affected
D
None of the above
Explanation: 

Detailed explanation-1: -As a result, the reabsorption of water from the glomerular filtrate is increased. When someone drinks lots of water, requirement of absorption of water decreases, so ADH release is suppressed.

Detailed explanation-2: -The only previously known chemical inhibitor of ADH release other than water is ethanol.

Detailed explanation-3: -It’s a hormone made by the hypothalamus in the brain and stored in the posterior pituitary gland. It tells your kidneys how much water to conserve. ADH constantly regulates and balances the amount of water in your blood. Higher water concentration increases the volume and pressure of your blood.

Detailed explanation-4: -SIADH happens when your body makes excess amounts of antidiuretic hormone (ADH). SIADH causes your body to retain too much water and commonly leads to hyponatremia, which is low levels of sodium in your blood. It’s treatable.
