Explanation:
Detailed explanation-1: -A scab is a dry, rough protective crust that forms over a cut or wound during healing. A scab starts to form as soon as the skin is injured. Blood platelets begin to clump together, forming a loose clot to stem the bleeding. When the clot dries, it turns into a scab.
Detailed explanation-2: -Scabs are meant to protect the wound from germs and other harmful bacteria while the wound is healing. Sometimes scabs can take more than a few weeks to completely heal. In some cases, they may leave behind a scar.
