Contractions in childbirth.

Explanation: During labor, uterine stretching stimulates oxytocin release, which increases contractions, causing more stretching and more oxytocin release until delivery — a classic positive-feedback loop. The other examples (blood glucose, pH, body temperature) are maintained by negative feedback mechanisms that restore values toward a set point.
