Storyboard Text

  • Thanks for taking me out Jay, I'm starving!
  • With the pizza being consumed and digested by both teens it causes their blood glucose levels to rise.
  • This pizza is so good!
  • In response to the rise of her blood glucose levels, Aly's body receptors sends a signal to the control center, the brain, which then allows the effector, the organ or cell that acts in response to stimulus, in our case the pancreas, to secrete insulin into the blood.
  • The insulin allows your body to use the sugars.
  • Afferent neurons are sensory neurons that carry nerve impulses from sensory stimuli towards the central nervous system and brain, while efferent neurons are motor neurons that carry neural impulses away from the central nervous system and towards muscles to cause movement.
  • So Aly, how does your body get these signals?
  • Thanks for dinner! Sleep well
  • After Aly's effectors reacted to the stimuli responses, her blood glucose levels went back to normal. Due to the negative feedback loop.
