Explain the concept of positive feedback. Give an example of a hormone that works through
positive feedback.
.
1- Positive feedback is the action of a hormone increasing the production of that hormone.
(This is the opposite of negative feedback).
2- One example is the action of oxytocin causing the uterus to contract during labor.
Oxytocin enhances the effect of the uterus contractions, causing more oxytocin to be
released. The positive feedback loop is stopped once the baby is born and the uterus no
longer needs to contract, stopping the production of oxytocin.
