ABSTRACT
Scabs are kind of gross. The brown crusty gunk that covers a nasty cut or scrape isn’t pretty, but it is very necessary. When the body gets a cut, scrape, or break in the skin, special blood cells called platelets form at the site. The platelets stick together like glue and form a clot that stops the bleeding. In the clot can also be found thread-like fibers called fibrin. They hold the clot together. The scab protects the body from infection entering the blood and skin.
