A scab is largely consisted of Platelets, clot forming cells. And, fibrin, thread like make that holds the clots together. When you cut yourself platelets stop the bleeding by clotting and fibrin helps hold the clots together to make a natural bandage we call a scab.
A scab is a collection of red blood cels called ‘platelets’ that gather over an area of broken skin like a cut or scrape. The platelets stick together and form a clot that prevents more bleeding. Scab formation is the first rection the body has to begin the healing process, and it can sometimes itch. Once the clot is no longer needed and the new skin cells have replaced it underneath, the scab falls off, revealing new, usually red-tinged skin.
