Quizplus · Accepted Answer

Thirst is experienced when water loss equals 2% of an individual's body weight or when there is an increase in osmolality. Dry mouth, hyperosmolality, and plasma volume depletion activate osmoreceptors (neurons located in the hypothalamus that are stimulated by increased osmolality).
