Enhancement of labor contractions is a good example of positive feedback mechanism because during labor, the hormone oxytocin is released, which stimulates contractions. The contractions then push the baby towards the birth canal and more oxytocin is released as a result, amplifying the contractions and leading to the birth of the baby. This is an example of a positive feedback mechanism because the initial stimulus (contraction) leads to a response (release of more oxytocin) that further enhances the stimulus (contraction), leading to a cascade of events that ultimately result in the birth of the baby.
