Homeostasis is a natural phenomenon which is body’s tendency to maintain internal stable and favorable environment against any situation that would tend to disturb its normal condition and function. Such as, If the temperature rises, the body loses heat by sweating or panting, via the latent heat of evaporation. If it falls, this is counteracted by increased metabolic action, by shivering and in fur or feather coated animals, by thickening the coat. Like temperature our body can sense the change in osmolarity and to maintain a stable condition body needs to persist on a certain osmolarity. Secretion of certain hormones can be stimulated by any change in the osmolarity to help maintain a certain level of osmolarity - briefly discuss the mechanism of action and biochemical function of such a hormone.
