MICROANATOMY

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: -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.
