WebApr 5, 2024 · The hormone that most affects the osmolarity of the blood is antidiuretic hormone (ADH). ADH is released by the pituitary gland, and it helps regulate the body's water balance. It does this by increasing the reabsorption of water from the urinary system back into the bloodstream, resulting in an increase in the osmolarity of the blood. WebRemember that in this setting ADH secretion will increase to conserve water, thus complementing the effect of low aldosterone levels to decrease the osmolarity of bodily fluids.
