In mammals, an increase in the concentration of sodium in the blood triggers the release of antidiuretic hormone (ADH) from the pituitary gland. As the concentration of sodium in the blood returns to previous levels, the release of ADH from the pituitary gland is reduced. Based on the information presented, what describes the most likely role of ADH in maintaining blood osmolarity?

In order to perform a more balanced form of processes inside the mammals body or as whole system there is always the requirement for  having a more specific form of mechanism called as the homeostasis. This process is required to attain a very balanced state of solutes and other liquids inside the body system of the humans. As, to have this position the mammals have certain secretions like the release of antidiuretic hormone (ADH) from the pituitary gland. Which, acts on the nephrons present inside the kidneys and directs it to absorb more amount of water and solutes, in order to prevent any more water loss.So, basically the secretion is done for avoiding any water and solute losses from the mammals body system in any form. Which would also result in a more balanced form of blood pressure and as a whole a more balanced form of water volume inside the body.
