Quizplus · Accepted Answer

The antidiuretic hormone (ADH) works through a negative feedback loop that encourages the kidneys to reabsorb water. When the body senses dehydration, ADH is released by the hypothalamus and travels to the kidneys. ADH stimulates the kidneys to reabsorb water from the urine, returning it to the bloodstream, thus reducing urine output and increasing overall blood volume. When the body is properly hydrated, ADH secretion decreases, and less water is reabsorbed, allowing for more urine production.
