Question

One of the fictional wizard Harry Potter’s most distinguishing features was the lightning-bolt-shaped scar he carried from his encounter with Lord Voldemort as a baby. A scar is a mark left on the skin where a wound has healed and has been filled in with fibrous connective tissue. You may not have encountered a dark wizard like Harry did, but most of us have scars from surgery, a skinned knee, or another injury. Any time that the dermis of the skin is damaged, a scar may be left behind as a result of the healing process. While the healing of this skin may not be magic, it is pretty amazing.

When the skin is injured, the body responds quickly to send blood to heal the area. The blood forms clots to help seal the area and dries to form a scab that will protect the tissue underneath as it heals. Next, immune cells are sent to fight any infection in the area, and increased blood flow brings oxygen and nutrients to the wound. Red blood cells help create collagen in the area, which forms the basis for new skin tissue. The wound begins to fill in with new tissue and skin forms over the surface of the wound. The wound will then pull together and get smaller, and a scar begins to form.

The resulting scar from an injury will appear different than the surrounding tissue. Scar tissue is less flexible and can sometimes appear redder or more shiny than surrounding skin. Over time, the scar will begin to fade, with smaller injuries often leaving hardly a trace. The deeper the injury is and the more jagged the edge of the wound, the more likely you are to have a scar.

How can you explain the process of tissue repair and scar formation process to your friend? What factors increase his likelihood of having a scar?

When your skin is injured, the body quickly sends blood to the area to form clots and protect it while it heals. Immune cells fight off any potential infection, and new skin tissue forms through a process involving collagen. After the stitches are taken out, the wound will start to close and a scar may form, which usually looks different from the surrounding skin. Factors like the depth of the injury and how jagged the wound edges are can increase the chances of a noticeable scar.
