PATHOLOGY

Detailed explanation-1: -Avulsion. Also known as a skin tear, an avulsion is a deep break to the skin, tearing it away from the underlying tissue. Wounds of this type are usually more serious and extensive.

Detailed explanation-2: -The term “scab” is used when a crust has formed by coagulation of blood or exudate. Scabs are found on superficial or partial-thickness wounds. Scab is the rusty brown, dry crust that forms over any injured surface on skin, within 24 hours of injury.

Detailed explanation-3: -The larger and deeper the scrape, the longer it will take to heal. A large, deep scrape may take up to 1 to 2 weeks or longer to heal. It’s common to have small amounts of fluid drain or ooze from a scrape. This oozing usually clears up gradually and stops within 4 days.
