What do white blood cells do in a scab?
Scab is the rusty brown, dry crust that forms over any injured surface on skin, within 24hrs of injury.Whenever our skin is injured due to any cut or abrasion, it starts bleeding due to blood flowing from the severed vessels. This blood containing platelets, fibrin and blood cells, soon clots, to prevent further blood loss. The outer surface of this blood clot, that is exposed to air, dries up (dehydrates) to form a rusty brown crust, called a scab, which cover the underlying healing tissues like a cap.The purpose of a scab is:to prevent further dehydration of the healing skin underneath,to prevent it from infections,to prevent any entry of contaminants from the external environment.Scabs generally remain firmly in place until the skin underneath has been repaired and new skin cells have appeared, after which it naturally falls off.
