Explanation:
Detailed explanation-1: -Blood clotting is an example of positive feedback since the action of the effector amplifies that of the stimulus. Negative feedback results in a response that opposes that of the original deviation from normal.
Detailed explanation-2: -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. The release of oxytocin result in stronger or augmented contractions during labor.
