In which phase of wound healing does the immune system work to prevent infection?

• A. Proliferative phase
• B. Maturation phase
• C. Inflammatory phase
• D. Restorative phase

Answer: (C)

The immune system actively works to prevent infection during the inflammatory phase of wound healing. This phase is characterized by the body’s immediate response to injury, which includes the activation of white blood cells, such as neutrophils and macrophages. These cells play a crucial role in fighting off pathogens that may enter the wound site, thereby reducing the risk of infection. During this phase, chemical signals are released that lead to increased blood flow and the migration of immune cells to the injured area. This helps to clean the wound by removing debris and bacteria, setting the stage for subsequent phases of healing. It’s essential for the inflammatory phase to be effective, as a compromised immune response can lead to infection and hinder the overall healing process. The other phases of wound healing, such as the proliferative phase and maturation phase, focus more on tissue formation and remodeling rather than immediate infection control, which is why this phase is vital for initiating protection against infections.
