Some examples of positive feedback are contractions in child birth and the ripening of fruit; negative feedback examples include the regulation of blood glucose levels and osmoregulation.

What is the most common feedback system?
Most biological feedback systems are negative feedback systems. Negative feedback occurs when a system's output acts to reduce or dampen the processes that lead to the output of that system, resulting in less output. In general, negative feedback loops allow systems to self-stabilize.
What are feedback in systems?
Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to feed back into itself.
What is an example of a system with positive feedback?
Positive feedback mechanisms are rare. It amplifies changes rather than reversing them. The release of oxytocin from the posterior pituitary gland during labor is an example of positive feedback mechanism. Oxytocin stimulates the muscle contractions that push the baby through the birth canal.

What is an example of a feedback system in the human body?
Regulating Temperature
A typical example of a negative feedback mechanism in the human body is the regulation of body temperature via endotherms. When the body's temperature rises above normal, the brain sends signals to various organs, including the skin, to release heat in the form of sweat.
