What is involuntary contractions of voluntary muscles to warm up?
  • Shivering
  • Sweating
  • Vasodilation
  • Vasoconstriction
If the environment gets cold, we will often shiver in order to:
  • keep body temperature the same as the external temperature
  • decrease body temperature
  • increase body temperature
  • regulate blood pressure
Homeostasis
  • allows for a wildly fluctuating internal environment
  • is impossible in vertebrates
  • is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation
When you are cold, you shiver and your blood vessels contract, which warms you up. When you are hot, you sweat and your blood vessels expand, which cools you down.
