Describe how adh secretion maintains plasma osmolarity levels during dehydration and water loading

Antidiuretic hormone (ADH) acts on the vascular system and the urinary system to regulate solute-water content in the body. During dehydration, secreted by the posterior pituitary gland, the hormone promotes reabsorption of water from urine in the renal tubules hence decreasing plasma osmolarity.
