Detailed explanation-1: -The release of oxytocin from the posterior pituitary gland during labor is an example of positive feedback mechanism. Oxytocin stimulates the muscle contractions that push the baby through the birth canal.

Detailed explanation-2: -Feedback loops are created when reactions affect themselves and can be positive or negative. Consider a thermostat regulating room temperature. This is an example of a negative feedback loop. As the temperature rises, the thermostat turns off the furnace allowing the room to rest at a predetermined temperature.

Detailed explanation-3: -The positive feedback cycle is maintained until the baby stops suckling. The production of oxytocin during childbirth is also self-limiting; release of the hormone is stopped once the baby is delivered.
