Question

Quizplus · Accepted Answer

The subfornical organ is a region of the brain that lacks a blood-brain barrier and is capable of monitoring angiotensin levels. When levels are high, it stimulates thirst and drinking behavior. The hypothalamus is also involved in regulating thirst and other basic physiological needs, but in this specific case, the subfornical organ is the more accurate answer. The cerebellum and thalamus are not directly involved in thirst regulation.
