Positive Feedback Mechanism

Positive feedback is a mechanism that is much rarer in a healthy body. Instead of restoring the body to a normal state, the positive feedback mechanism causes an even greater change. An example of positive feedback can be found in the release of oxytocin, a hormone that intensifies the contractions that take place during childbirth. As the baby’s head is ready to move out of the mother’s body, oxytocin increases and the levels of contractions increase thus pushing the baby out. In this instance, the body responds to an event with more “force” or in a stronger way.
