Question

Quizplus · Accepted Answer

ADH (antidiuretic hormone) controls the balance of water in the body and is released in response to dehydration or low blood volume. On a hot day, the body loses water through sweating, leading to dehydration and triggering the release of ADH to conserve water. Therefore, a person working hard on a hot day and sweating a lot would have a higher concentration of ADH in their blood.
