What is the purpose of inflammation?

• A. Provides complete pain relief
• B. Occurs only after healing
• C. Protective response and necessary for healing
• D. Is not related to tissue repair

Answer: (C)

Inflammation is a protective response that initiates and supports tissue repair after injury. Its main purpose is to contain the injurious stimulus, remove damaged or infectious material, and deliver immune cells and nutrients to the site so healing can begin. Chemical mediators cause blood vessels to dilate and become leaky, bringing in neutrophils and macrophages to clear debris and fight infection, while also releasing signals that start tissue repair and remodeling. Pain can be present, but inflammation’s role is not to provide complete pain relief; rather, it is the necessary process that enables healing to proceed. Inflammation occurs as part of healing, helping to lay down new tissue, form granulation tissue, and eventually remodel the area. The other statements misstate its purpose or timing, whereas inflammation serves as the protective, enabling step in tissue repair.
