Thirst activates osmoreceptors following an increase in which blood plasma component?
A)Antidiuretic hormone
B)Aldosterone
C)Hydrostatic pressure
D)Osmotic pressure

Question

Quizplus · Accepted Answer

Thirst is experienced when water loss equals 2% of an individual's body weight or when osmotic pressure increases. Dry mouth, hyperosmolality, and plasma volume depletion activate osmoreceptors (neurons located in the hypothalamus that are stimulated by increased osmotic pressure). Increased antidiuretic hormone, aldosterone, and hydrostatic pressure do not activate osmoreceptors.
