Answer
When there is a decrease in plasma VOL about 10 to 15% and/or when there is an increase in plasma osmolality which ranges 2 to 3% which in turns causes a dry mouth and the drinking center begins to excite. This excitement happens due to the osmorecptors ges triggered and depolaries while the water is controlled by the hypertonic ECF, it goes through osmosis. All of these parts create a sense of thirst. This sense begins because of hte mucosa in the mouth and the throat are moistened. This then continues on as the intestines and the stretch receptors are activated and in result a feeback occurs that impedes the thirst center.
