Storyboard Text

  • 
  • Sally what is a negative feedback? 
  • 
  • A negative feedback is when your body changes a variable back to its original state.
  • 
  • oh okay, so would the control of blood sugar be a negative feedback?
  • 
  • Yes exactly! When your blood sugar rises the receptors in your body sense a change.
  • 
  • In return, the control center which is the pancreas in this case starts to create insulin into the blood to lower blood sugar levels. 
  • 
  • Once the blood sugar levels in our body return back to homeostasis your pancreas will stop releasing insulin.
