Negative Feedback Temperature

• Temperature levels increase

  Normal body temperature
• High temperatures


  Enzymes denature (change shape) and will no longer work
• Negative feedback loop

  Levels decrease
• Effectors

  • Body sweats
  • Muscles cause hairs to lie flat allowing heat loss
• Coordination centre


  • Receives and processes information
  • Organises the response (electrical impulse or hormone release)
• Homeostasis is dependent on a negative feedback loop
• Respiration

  Needs enzymes
• Body temperature needs to remain constant to allow enzymes to work optimally
• Receptor cells
