Examples of positive feed back mechanisms are very few. One example is that of uterine contractions during child birth. Normal state of uterus is un contacted, one contraction instead of commanding to come to normal gives a message to continue further (positive feedback till the delivery is completed).

'Too much, slow down or too little, speed up' -this is the feedback mechanism. the body has a mechanism to maintain a normal state. Whenever there is a change in this state there are messages through the body systems to increase if there is a fall below the normal, or decrease, if there is a rise above the normal. This kind of ordering for the opposite Is negative feedback to restore the normal state.
