How do cuts and grazes heal themselves

cuts and grazes

When we cut or graze ourselves, the body is able to heal itself. When the skin incurs a wound, platelets in the blood congregate at the site of the wound to form a temporary clot. This usually happens as soon as a wound is exposed to the air. This quickly plugs the wound.
White blood cells gather around the wound site of the wound to form a temporary clot. This usually happens as soon as a wound is exposed to the air. This quickly plugs the wound.

White blood cells gather around the wound site to kill invading microbes, helping to prevent infection.

New cells eventually grow into the wound replacing the damaged tissue. For a small cut or graze , this usually takes a couple of days. Soon the clotted material, which has formed a scab, falls off to reveal clean, new skin underneath. Sometimes we protect our grazes and cuts with plasters whilst our bodies deal with the repair.
