Final answer:
Entry/exit wounds can reflect the severity of internal organ/structure injuries. Sharp objects cause clean cuts to the bone, while blunt instruments can cause fractures or contusions. Severity of internal injuries depends on the type of weapon and force used.
Step-by-step explanation:
Entry/exit wounds can be reflective of the severity of internal organ/structure injuries. In cases of perimortem trauma, sharp objects like swords or axes can cause clean cuts to the bone, indicating high energy and skill behind the blow. These injuries are observed in the majority of cases. On the other hand, injuries caused by blunt instruments like stones or heavy objects may result in fractures or contusions. The severity of internal injuries can vary based on the type of weapon used and the force applied.
