Final answer:
An abrasion is a wound in which the skin is still intact. It occurs when the outer layer of the skin is scraped or rubbed away, but the deeper layers remain intact.
Step-by-step explanation:
A wound in which the skin is still intact is called an abrasion. An abrasion occurs when the outer layer of the skin is scraped or rubbed away, but the deeper layers remain intact. It is typically caused by friction or scraping against a rough surface. Examples of abrasions include skinned knees or elbows from falling on pavement. Unlike lacerations or open fractures, there is no break in the skin with an abrasion.
