When blood flows from a cut, the body’s response is to create clots which prevent the loss of blood through a positive feedback mechanism.

Platelets in the blood will begin to stick to the wounded area which produce substances that will attract platelets. As the platelets continue to be released, platelet plug will form which leads to the development of a clot.
