Answer:
Abrasion, Laceration, Puncture, Avulsion
Explanation:
Abrasion: when the skin rubs or scrapes on a rough surface, can possibly cause bleeding and, if severe enough, can cause an avulsion
Laceration: deep cut or tear in the skin, it is often caused by shrapnel of any kind, such as of a piece of glass or a fragmenting object such as a hollow-point bullet or a shotgun shell
Puncture: a hole caused by a sharp pointy object such as a nail, needle, or a knife.
Avulsion: complete tearing away of the skin or tissue, often called degloving. These injuries are usually the most life-threatening.
