Storyboard Text

  • You know, today is a perfect day for a jump in the pool!
  • Here I go!!
  • I forgot we don't have a heated pool and that it's the middle of December...
  • One lovely "summer" afternoon, Tommy decided to jump into the pool.
  • That probably wasn't my best idea, I'm still shivering, as my body is trying to create warmth to maintain homeostasis!
  • He ran outside so fast he didn't realize...
  • Oh man, now I'm sweating because the fire's heat is too hot! My body is trying to cool me down and regulate my body temperature!!
  • was the middle of December, and it was freezing cold.
  • I'm feeling much better now that homeostasis in my body was reached again!
  • Tommy quickly ran back inside as his skin had already sent afferent signals to his brain which made the brain send efferent signals to tell his muscles to shiver (to produce heat).
  • Once he sat directly next to the fire for a while, his skin started getting hot and sent afferent signals to his brain AGAIN, except this time the brain sent efferent signals to the sweat glands, so that he could cool down.
  • As Tommy's body temperature reverted to a homeostatic condition, he decided to not blindly jump in the pool in the middle of December. Ever. Again.
