Examples of positive feedback mechanisms

  1. Childbirth
During labor release of oxytocin intensifies and speeds up the contraction. The increase I contraction causes more oxytocin to be released and the cycle goes on until the baby is born 2. Blood clotting Once a vessel is damaged, platelets start to cling to injured site release chemicals that attract more platelets. The platelets continue to pile up and release chemicals until a clot is formed.
