The only hormone here wich control water reabsorption is antidiuretic hormone (vasopressin).
Antidiuretic hormone (ADH), also known as vasopressin, is involved in the reabsorption of water by the body. This hormone plays a role in the regulation of blood volume and the concentration of water in the body. It is secreted by the hypothalamus and released by the pituitary gland. Its secretion is regulated by the osmoreceptors of the brain and by the baroreceptors of carotids, auricles and pulmonary vessels.
Plants absorb carbon dioxide (CO2) and release oxygen for humans and animals to breathe in. Afterward, they'll release CO2 for plants to absorb, which forms a cycle.
