Principles of Homeostasis

• Homeostasis= The regulation of the internal conditions of a cell to maintain optimum conditions for function from internal and external responses
• What internal conditions are controlled?

  • Body temperature
  • Water levels
  • Blood glucose concentration
• A control system must contain...


  • Receptor (detects stimuli)
  • Co-ordination Centers
  • Effectors
• Why do we need to do homeostasis to survive?


  To maintain balance the internal conditions like enzymes so everything works optimally alongside cell functions
• Negative Feedback: A system that responds to a change in the environment by returning the system to its original state
