Wounds

A wound is an injury or an abnormal break in the continuity of the skin or-other tissues. In an external wound, there is danger that germs will enter the wound and cause an infection. If the wound is deep, severe bleeding may occur or there may be serious damage to structures within the body, such as the bowel, heart, lungs, or brain.

What are the types of wounds?

A wound may be open or closed. In the open wound skin is broken and blood escapes out. In a closed wound skin is not broken.
