Question

What type of wound occurs when the skin scrapes against a hard surface and tiny blood vessels break in the outer layer of skin?

Answer 1

A, Abrasion. An avulsion would be when the flesh is basically torn away, as if someone took a spoon and removed flesh. A laceration would be a large cut, such as a wound inflicted by a knife. Puncture wounds would be when something punctures the skin, i. e., I stepped on a nail, giving me a puncture wound.

Answer 2

When the skin scrapes against a hard surface and tiny blood vessels break in the outer layer of skin, this is called an "A. abrasion". Lacerations affect deeper tissue layers.
