AP PSYCHOLOGY

Detailed explanation-1: -If the temperature is too high, the hypothalamus can initiate several processes to lower it. These include increasing the circulation of the blood to the surface of the body to allow for the dissipation of heat through the skin and initiation of sweating to allow evaporation of water on the skin to cool its surface.

Detailed explanation-2: -When your hypothalamus senses that you’re too hot, it sends signals to your sweat glands to make you sweat and cool you off. When the hypothalamus senses that you’re too cold, it sends signals to your muscles that make your shiver and create warmth. This is called maintaining homeostasis.

Detailed explanation-3: -If the body is exposed to cold external temperatures and the internal temperature drops below the set point, the brain sends a message to the muscles. Muscles then shiver in order to produce heat. A message is also sent to the peripheral blood vessels to constrict.

Detailed explanation-4: -Sweating plays an important role in the regulation of human body temperature through dissipating thermal energy from the skin surface when water in the sweat evaporates. Sweat counteracts heat stress after we exercise and allows us to survive in extreme climates.

Detailed explanation-5: -Sweating: Your sweat glands release sweat, which cools your skin as it evaporates. This helps lower your internal temperature.
