Negative Feedback Loop

Negative Feedback Loop

Storyboard Text

  • It's so hot today!
  • I KNOW! It's like 110 degrees in this desert!!
  • My receptor cells are actively reacting to this heat!
  • Yeah! Interesting, though, it sends this information to our control center through the afferent pathway.
  • Yes! Even though I'm not telling my brain to do it, it's sending important commands to our effectors via the efferent pathway, the sweat glands!
  • True! True! All of this making our sweat glands release sweat making us all clammy and sweaty.. ugh
  • Exactly and that's our response leading to heat loss!
  • Ugh its so hot!
  • And that's how we maintain homeostasis: the state of balance. Negative feedback loops are so cool, aren't they?
  • Exactly, but can we stop talking about homeostasis and just go home already!
  • Nah, let's enjoy the beautiful view and talk more about how other negative feedback loops maintain homeostasis! :)
  • NOO.. I want to go home :(
