Which term refers to the condition where the skin has been scraped off?

The correct term for the condition where the skin has been scraped off is "abrasion." An abrasion occurs when the top layer of skin is removed, often due to friction against a rough surface. This type of injury typically results in superficial damage and may cause some bleeding, depending on the depth of the scrape. Abrasions are commonly seen in sports and physical activities, where falls or slides on the ground can lead to skin being worn away.

In contrast, a laceration refers to a deeper and more irregular tear in the skin, often caused by sharp objects or injuries. A contusion, also known as a bruise, results from blunt force trauma, leading to bleeding under the skin without breaking the skin's surface. An avulsion involves a portion of the skin being forcibly torn away, which is more severe than an abrasion and may lead to significant tissue loss. Therefore, among these options, abrasion specifically describes the scraping away of skin.
