Entrance and exit wounds are two types of gunshot wounds that occur when a bullet enters and exits the body, respectively. They are often used to provide important information about the trajectory of the bullet, the type of firearm used, and the extent of the injury.
An entrance wound is typically smaller than an exit wound and may be surrounded by a ring of bruising or abrasion known as an abrasion ring or muzzle stamp. The size and shape of the entrance wound can provide important clues about the type of firearm and the distance between the shooter and the victim.
An exit wound, on the other hand, is typically larger and more irregular in shape than an entrance wound. The size and shape of the exit wound can also provide important information about the type of firearm and the distance between the shooter and the victim. The presence of bone fragments, clothing fibers, or other debris in the exit wound can also provide important clues about the trajectory of the bullet.
In some cases, the entrance and exit wounds may be in different locations on the body, indicating that the bullet passed through multiple structures or organs. This can make it more difficult to determine the trajectory of the bullet and the extent of the injury.
Medical professionals will typically examine both the entrance and exit wounds when treating a gunshot victim. They may use this information to determine the best course of treatment and to provide information to law enforcement or other investigators.
