Final answer:
An eschar is a scab that forms over a wound during the healing process.
Step-by-step explanation:
An eschar is a scab that forms over a wound during the healing process. It is a dry, dark-colored crust that protects the underlying tissue from infection and further damage. The formation of an eschar is a normal part of the healing process and indicates that the wound is in the later stages of healing. It is important to keep the eschar clean and dry to promote healing and prevent infection.
