physiological wound caused by an external source
Injury means a harm or hurt.
Usually an injury is when the body or a part of the body is damaged by something outside of the body. Another word for injury to a body is trauma.
Injury can be by:
- Environmental – Burns from heat or injury from cold
- Penetrating injury – when a sharp object like a knife pierces the body
- Blunt injury – when something hits the body (like punching someone or falling from a tree)
- Chemical – being hurt by chemicals like burns from acid
Injury can be accidental or intentional. In an intentional injury a person tries to hurt another. (Intentional injury is also called non-accidental injury). Accidental injury is without meaning to hurt someone. A traffic collision for example may injure someone accidentally.
