GENERAL HISTOLOGY

Detailed explanation-1: -Scabs usually decrease in size and fall off as the new skin under the scab is formed. During healing, a scab may accidentally get rubbed off, which causes the wound to start bleeding again. Treat the wound and protect the area so the healing process can begin again.

Detailed explanation-2: -The preferred medical term is crust or eschar, the latter being Greek for scab. The edge of an eschar can keep a wound from closing by secondary intention. And an eschar is a sign that a wound is too dry to heal as fast as possible. Having noted that, a crust is the best nature can do in many situations.
