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.
An example of positive feedback and homeostasis is when a person has a cut or damage to a blood vessel. To stop bleeding, a positive feedback response is initiated in which platelets in the blood accumulate and clot around the wound. This relatively quickly stops the cut from bleeding.
