Wounds are injuries that break the skin or other body tissues. They include cuts, scrapes, scratches, and punctured skin. They often happen because of an accident, but surgery, sutures, and stitches also cause wounds. Minor wounds usually aren't serious, but it is important to clean them.

Types of Wounds:

Abrasion: An abrasion occurs when your skin rubs or scrapes against a rough or hard surface. Road rash is an example of an abrasion. There’s usually not a lot of bleeding, but the wound needs to be scrubbed and cleaned to avoid infection.

Laceration: A laceration is a deep cut or tearing of your skin. Accidents with knives, tools, and machinery are frequent causes of lacerations. In the case of deep lacerations, bleeding can be rapid and extensive.

Puncture: A puncture is a small hole caused by a long, pointy object, such as a nail or needle. Sometimes, a bullet can cause a puncture wound. Punctures may not bleed much, but these wounds can be deep enough to damage internal organs. If you have even a small puncture wound, visit your doctor to get a tetanus shot and prevent infection.

Avulsion: An avulsion is a partial or complete tearing away of skin and the tissue beneath. Avulsions usually occur during violent accidents, such as body-crushing accidents, explosions, and gunshots. They bleed heavily and rapidly.

What are the types of wound healing?

There are three main types of wound healing, depending on treatment and wound type. These are called

Primary: Primary wound healing usually occurs in the case of aseptic wounds or fresh injuries. The wound edges have smooth borders and are in close vicinity. Primary wound healing occurs e.g. after a surgical incision in which the edges of the wound are connected by a suture. In general, such wounds will heal within 6 – 8 days.

Secondary: Secondary intention healing means a wound will be left open (rather than being stitched together) and left to heal by itself, filling in and closing up naturally. It will mean you need regular dressings to the area for up to six weeks, but the time to full healing depends on the size, depth and site of the wound.

Tertiary Wound: Healing by tertiary intention is the intentional delay in closing a wound. On occasion, wounds are left open (covered by a sterile dressing) to allow an infection or inflammation to subside.
