Xytocin is a hormone that controls many responses and functions in the body, including uterine contractions during labor. the movement of the baby down the uterus and into the cervix activates stretch receptors, which stimulate the hypothalamus to release more oxytocin and increase the frequency of contractions. this is an example of

a positive feedback loop

Explanation:

A positive feedback can be define as a process in this the end product of the reaction or action in the body causes more of the action to occur in the feedback loop. This process enhances the effect of original action.

The example of positive feedback is the process of childbirth and labor. During childbirth the fully developed fetus exerts pressure down the uterus, this stimulates the oxytocin hormone. The release of oxytoxin increases the contractions of the uterine muscles and cervix.
