Which phase of healing is characterized by an increase in redness and swelling in the affected area?

The inflammation phase is a crucial part of the healing process, characterized by an increase in redness and swelling in the affected area. This phase occurs immediately after an injury and serves several important functions.

During this phase, the body's immune response is activated. Blood vessels expand (vasodilation) to allow more blood to flow to the site of injury, which results in increased redness and warmth. Additionally, plasma and other fluids seep into the area, leading to swelling. This localized swelling is an essential part of the healing process, as it brings white blood cells and nutrients that help to clean up debris and prevent infection.

The inflammation phase also acts as a signal to the body that repair is needed, prompting the next phase of healing. While other phases of healing involve tissue regeneration and remodeling, the inflammation phase’s distinct characteristics of redness and swelling are critical indicators that the body is responding to injury. These signs are essential for a proper diagnosis and management of soft-tissue injuries in an emergency medical context.
