Positive feedback is a mechanism that amplifies a response, leading to a greater change in the same direction. In childbirth, the hormone oxytocin stimulates the uterus to contract, which pushes the baby towards the birth canal. As the baby moves downwards, it stretches the cervix, which triggers the release of more oxytocin, leading to stronger contractions. This cycle of oxytocin release and stronger contractions continues until the baby is born.
