Uterine contractions during childbirth
Step-by-step explanation:
Positive feedback mechanisms amplify or reinforce changes that have occurred in the body rather than counteracting them. In the case of uterine contractions during childbirth, the initial contractions of the uterus cause the release of the hormone oxytocin, which then stimulates further contractions. This positive feedback loop continues until the baby is born.
In contrast, body temperature control, maintenance of blood pressure, and control of blood sugar are all examples of negative feedback mechanisms, which work to maintain a stable internal environment by counteracting changes that occur in the body.
