Detailed explanation-1: -Antidiuretic hormone stimulates water reabsorbtion by stimulating insertion of “water channels” or aquaporins into the membranes of kidney tubules. These channels transport solute-free water through tubular cells and back into blood, leading to a decrease in plasma osmolarity and an increase osmolarity of urine.
Detailed explanation-2: -Sensors in your body detect when your blood volume changes and needs more ADH. These sensors talk to your brain and the pituitary gland releases ADH into your bloodstream. When ADH makes it to your kidneys, it signals them to conserve water and produce more concentrated urine.
Detailed explanation-3: -ADH then acts primarily in the kidneys to increase water reabsorption, thus returning the osmolarity to baseline.
