Basic Homeostasis

• Pathophysiology

  Physiological processes associated with disease or injury
• Homeostasis


  The stable condition of an organism and of its internal environment
• Feedback control

  1. Feedback loop: Body's general control system

  2. Nerve endings feed information to a control center in the brain that compares actual temp to the normal temp

  3. Negative feedback: Opposes change in controlled condition

  4. Positive feedback: Amplifies occurring change
• Normal fluctuations
