What is the term for the wearing away or rubbing away of tissue by friction?

• A. Abrasion
• B. Contusion
• C. Laceration
• D. Friction Burn

Answer: (A)

The term for the wearing away or rubbing away of tissue by friction is abrasion. An abrasion occurs when the skin or surface of an organ is scraped or rubbed off, typically due to contact with a rough surface. This type of injury often affects the outer layer of the skin, known as the epidermis, which may result in pain, bleeding, or the formation of a scab as the body heals. Other terms provided do not effectively describe this specific type of injury. A contusion refers to bruising, which is the result of blood vessels breaking under the skin due to blunt force trauma, but it does not involve the wearing away of the tissue. A laceration describes a tear or cut in the skin or tissue that may vary in depth and shape, typically caused by sharp objects. A friction burn, while it relates to skin injury from rubbing, specifically involves heat generated by friction causing a burn rather than merely the removal of tissue. Thus, abrasion is the most accurate term for the scenario presented in the question.
