Wound care

Wound is an injury involving an external or internal break in body tissue, usually involving the skin. It occurs when the skin is broken or damaged because of injury. Causes of injury may be the result of mechanical, chemical, electrical, thermal, or nuclear sources. The skin can be damaged in a variety of ways depending upon the mechanism of injury. Wounds fall into two broad categories: open or closed. In a closed wound, tissue damage and bleeding occur under the surface of the skin. Examples of closed wounds include bruises. An open wound involves a break in the skin that leaves the internal tissue exposed. Open wounds may result from falls, blunt trauma, and surgery.
