Best example of positive feedback is the release of oxytocin during childbirth. Oxytocin is a reproductive hormone in females. Though it is also secreted in males, its function is yet unclear. Secretion of oxytocin occurs in response to nervous stimulation of the hypothalamus. It stimulates and enhances labor contractions.
You see, oxytocin continues to be released as long as the baby is in the birth canal. But once labor is complete and the baby is no longer in the birth canal, the cervix is not being stretched anymore. This lack of the physical signal of stretching is what stops the positive feedback loop, and labor comes to an end.ut once labor is complete and the baby is no longer in the birth canal, the cervix is not being stretched anymore.
