Which of the following stimulate the thirst center in the hypothalamus? Group of answer choices None of these stimulate the thirst center in the hypothalamus. Angiotensin II levels in the blood increase. All of these stimulate the thirst center in the hypothalamus. Osmoreceptors detect an increase in the extracellular fluid osmolarity. Baroreceptors detect a decrease in blood pressure.
