Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The concentration of water in the blood is controlled by the kidneys in response to the presence of a hormone released from the brain. Select any of these actions that would alter the water potential/concentration of the blood plasma.
A
Consumption of fatty foods
B
Consumption of salty foods
C
Excess sweating
D
Excess consumption of water
E
Using certain medications (diuretics)
Explanation: 

Detailed explanation-1: -Water levels in the body are controlled by antidiuretic hormone (ADH), which is produced in the hypothalamus and triggers the reabsorption of water by the kidneys. Underproduction of ADH can cause diabetes insipidus.

Detailed explanation-2: -Antidiuretic hormone (ADH) is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced.

Detailed explanation-3: -ADH primarily affects the ability of the kidney to reabsorb water; when present, ADH induces expression of water transport proteins in the late distal tubule and collecting duct to increase water reabsorption. Several disease states arise when the body loses control of ADH secretion or responds to its presence.

Detailed explanation-4: -The water content of the blood is controlled by a hormone called anti-diuretic hormone (ADH). Different amounts of ADH are released into the bloodstream by a gland in the brain according to the concentration of the blood plasma .

Detailed explanation-5: -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.
