What type of wound occurs with no break in the skin?

A closed wound is characterized by tissue damage that occurs beneath the surface of the skin while the skin remains intact, which means there is no visible break or opening. This type of wound may involve bruising or contusion, where the underlying blood vessels are damaged, leading to bleeding within the tissues. The skin area may appear normal, and the injury can result from impact or trauma without cutting the skin.

In contrast, an open wound involves a break in the skin, which can include abrasions, lacerations, or surgical incisions. Punctures are specific types of open wounds caused by pointed objects piercing the skin. Incisions are also open wounds, typically resulting from sharp objects such as knives or surgical tools. Understanding these distinctions is crucial for effective assessment and treatment in clinical patient care.
