MICROANATOMY

Detailed explanation-1: -Our internal body temperature is regulated by a part of our brain called the hypothalamus. The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C. If our temperature is too low, the hypothalamus makes sure that the body generates and maintains heat.

Detailed explanation-2: -The hypothalamus is an area of the brain that produces hormones that control: Body temperature. Heart rate. Hunger. Mood.

Detailed explanation-3: -In homeotherms, temperature homeostasis is regulated primarily in the preoptic area (POA) of the hypothalamus.

Detailed explanation-4: -On most days, the hypothalamus reacts to increases in outdoor temperature by sending messages to the blood vessels, telling them to dilate. This sends warm blood, fluids and salts to the skin, setting off the process of evaporation.
