Positive feedback loops enhance or amplify changes; this tends to move a system away from its equilibrium state and make it more unstable. Negative feedbacks tend to dampen or buffer changes; this tends to hold a system to some equilibrium state making it more stable.

• Positive and negative feedbacks are control systems that help regulate process rates and homeostasis in the body.
• Both feedbacks are important for an organism to regulate its internal processes.
• In positive feedback, there is a direct positive correlation between the concentration and the process rate.
• Negative feedback controls the process rate to prevent substance accumulation.
• As compared to negative feedback, positive feedback is less frequent, stable, and intuitive.
• Negative feedback resists change but positive feedback enhances it.
• Generally, positive feedback has a wider range than negative feedback.
• Positive feedback may be associated with vicious cycles and illnesses while negative feedback is closely related with maintaining good health.
