HYPOTHALAMUS
Texto do Storyboard
- A healthy body functions best at an internal temperature of about 37°C.
- However, everyone has their own "natural" body temperature, which may be slightly higher or lower than the average. Our bodies often adjust their temperature in response to changes in their internal conditions.
- The hypothalamus, a part of our brain, controls our internal body temperature. It is responsible for many functions, but the two of the most important are maintaining homeostasis and controlling hormones.
- The hypothalamus ensures that the body produces and maintains heat when our temperature drops too low. If our current body temperature is too high, heat is released or sweat is produced to cool the skin.
- Thermoregulation is the process by which the body maintains its internal temperature stable. Its aim is to return your body back to homeostasis.
- The hypothalamus regulates body temperature by stimulating reflexes that cause vasodilation and sweating when the body is too hot and vasoconstriction and shivering when the body is too cold.
