Positive feedback mechanisms are designed to bring about a rapid change in the body. These mechanisms amplify or reinforce the original stimulus to produce a larger response. This can be useful in situations where a rapid response is needed, such as blood clotting or childbirth. Positive feedback mechanisms do not help maintain a constant internal environment or anticipate changes in the environment, and they do not return a variable toward the set point.
