Detailed explanation-1: -Water homeostasis is achieved by regulation of water intake and water loss by the kidneys. The former is achieved by sensations of thirst that motivate water acquisition, whereas the latter is regulated by the antidiuretic action of vasopressin.
Detailed explanation-2: -The kidneys regulate the fluid and electrolyte balance of the body by continually filtering the blood. This is vital to maintain a constant extracellular fluid volume and composition.
Detailed explanation-3: -The experiments showed that the kidney plays a dual role in the system of the osmoregulatio mechanism. Since this organ is supplied with osmoceptors, apart from its excretory function it acts as an informant indinating the state of osmotic pressure in the local and general blood circulation.
