Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What does ADH do to the collecting duct?
A
Allow more water to be absorbed into blood
B
Prevent water moving between nephron and blood
C
Allow more water to be absorbed into nephron
D
Allow glucose to be absorbed back into blood
Explanation: 

Detailed explanation-1: -[2] Therefore, slight elevations in osmolarity result in the secretion of ADH . ADH then acts primarily in the kidneys to increase water reabsorption, thus returning the osmolarity to baseline.

Detailed explanation-2: -If plasma osmolality increases, it stimulates secretion of ADH, which acts at the collecting duct of the nephron where it causes reabsorption of only water and producing concentrated urine.
