What is a closed wound?

In a closed wound, the skin’s surface is not broken; therefore, tissue damage and any bleeding occur below the surface. The simplest closed wound is a bruise. A bruise develops when the body is bumped or hit, such as when you bump your leg on a table or chair.

The force of the blow to the body damages the soft-tissue layers beneath the skin. This causes internal bleeding. Blood and other fluids seep into the surrounding tissues, causing the area to swell and change color.

A more serious closed wound can be caused by a violent force hitting the body. This type of force can injure larger blood vessels and deeper layers of muscle tissue, which may result in heavy bleeding beneath the skin and damage to internal organs.
