Symptoms of inflammation are seen at the site of any injury. In a very short time, the edges of the wound will be found to be more reddened than the surrounding skin, and the tissues will fell somewhat tenser and slightly warmer near the wound. The around the wound will appear to be somewhat raised; it will be painful symptoms of wound infection will be present.

There is increased blood supply to the wound area. The capillaries and veins dilate wildly and the blood, flowing rapidly at first, slows gradually. It produces redness and heat.

As the capillaries dilate, their walls become permeable, so that serum and white blood cells, and red blood cells to a lesser degree, escape into surround tissues. This movement of fluid is called exudation. A clear fluid discharge is serious. Cloudy creamy exudate is purulent and the one containing blood is haemorrhagic or sanguineous. This increase of fluid and blood cell, extending into the tissues accounts fro swelling and pain.

Normally, the infection subsides within four to five days. If the infection is controlled within four to five days, the proliferation phase starts.

A stab is formed over the wound, which protects the underlying tissues from contamination. The cells multiple and fill the defect. The blood vessels bud and the circulation is established. Finally, a scar is formed leaving a mark at the place of injury.
