Quizplus · Accepted Answer

Vasopressin is a hormone that is released by the pituitary gland in response to low water levels in the body. It works to conserve water by reducing urine output and increasing water reabsorption in the kidneys. Therefore, in the case of the explorer who has been lost in the desert for two days with very little water, we would expect to observe elevated vasopressin levels in order to conserve water and prevent dehydration.
