Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
ADH is released by the pituitary gland when ____
A
The blood is too concentrated
B
The blood has the same osmolarity as urine
C
The blood is too dilute
D
The blood is too weak
Explanation: 

Detailed explanation-1: -ADH is normally released by the pituitary in response to sensors that detect an increase in blood osmolality (number of dissolved particles in the blood) or decrease in blood volume. The kidneys respond to ADH by conserving water and producing urine that is more concentrated.

Detailed explanation-2: -This hormone helps the kidneys control the amount of water your body loses through the urine. SIADH causes the body to retain too much water. ADH is a substance produced naturally in an area of the brain called the hypothalamus. It is then released by the pituitary gland at the base of the brain.

Detailed explanation-3: -ADH is released by the pituitary gland when the blood is too concentrated and it causes the kidney tubules to become more permeable . This allows more water to be reabsorbed back into the blood during selective reabsorption.
