Answer:
Hypothalamus of human body system interact to perform temperature regulation along with nervous system and endocrine system.
Explanation:
Hypothamus is an important part of our lower brain that play a significant role in regulation of body temperature.
Hypothalamus works with nervous system along with the other parts of our body such as blood vessels,skin and sweat gland to maintain temperature homeostasis of human body.
When our body temperature rises at that time hypothalamus slows down the rate of metabolism of our body to restrict further increase in our body temperature and also dilates the blood vessels present beneath the skin so that body can liberate heat to the environment.
on the other hand when the body temperature decreases at that time hypothalamus increases the metabolic rate of our body to increase the body temperature and also the constrict the blood vessels present under the skin.
