Homeostasis: Principles and Negative Feedback

Homeostasis: Principles and Negative Feedback

  • Positive feedback amplifies changes, accelerating the system away from its equilibrium.
  • Negative feedback counteracts changes, pushing the system back towards its equilibrium.
  • In homeostasis context, positive feedback could be labour where contractions become stronger until a baby is delivered.
  • An example of negative feedback in homeostasis is body temperature regulation (getting goosebumps when cold, sweating when hot).
  • A comparison table might include aspects such as whether the feedback amplifies or counteracts changes, instances where they occur, and their effect on homeostasis.
  • The task also mentions possible interpretation of information relating to either negative or positive feedback.
