There are 6 stages which your body does to react to the cut and healing it. First, white blood cells come to the wound. Second, platelets activated by the damage start to stick together to form a loose plug. Third, fiber forms to trap blood cells and create clot that reinforces platelet plug. Fourth, clot halts bleeding and enables repairs to take place.Fifth, scab forms where scab forms. Finally, white blood cells hunt down the intruders before obliterating them, while blood stops leaking from the blood vessel.
