Final answer:
True, the thirst center is located in the hypothalamus and the SFO of the brain, which regulates the body's water balance through autonomic and endocrine systems.
Step-by-step explanation:
The statement that the thirst center is located in the hypothalamus and the subfornical organ (SFO) of the brain is true. The hypothalamus is a critical area of the brain responsible for regulating many autonomic system processes, including the sensation of thirst.
When there is a decrease in water levels in the blood, indicating dehydration, osmoreceptors located in the hypothalamus detect the increased concentration of solutes, which is referred to as osmolality. These osmoreceptors then trigger a physiological thirst response, signaling the body to increase water intake.
Additionally, the hypothalamus releases antidiuretic hormone (ADH) to reduce water loss and manage hydration levels. The hypothalamus, considered the master control center for homeostasis through the autonomic and endocrine systems, plays a key role in maintaining the body's water balance.
