Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The hormone ADH usually acts on the
A
Glomerulus
B
Proximal convoluted tubule
C
Loop of Henle
D
Distal convoluted tubule and collecting duct
Explanation: 

Detailed explanation-1: -ADH facilitates water reabsorption from latter parts of the tubule (Distal convoluted tubule and Collecting duct), thereby preventing diuresis. An increase in body fluid volume can switch off the osmoreceptors and suppress the ADH release to complete the feedback.

Detailed explanation-2: -ADH increases the permeability to water of the distal convoluted tubule and collecting duct, which are normally impermeable to water. This effect causes increased water reabsorption and retention and decreases the volume of urine produced relative to its ion content.

Detailed explanation-3: -Excretory Physiology : Example Question #7 ADH acts on the collecting tubule of the kidney to allow for water reabsorption. The reabsorption of water will raise the blood volume and as a result, the blood pressure will also increase.
