What function does inflammation serve in the innate immune response?

Inflammation plays a critical role in the innate immune response, primarily by increasing fluid and white blood cells in the affected tissue. When tissue is damaged or infected, inflammatory mediators are released, leading to several physiological changes. These changes include increased blood flow to the area, which brings additional white blood cells (such as neutrophils and macrophages) to help combat pathogens and promote healing. The increase in fluid also leads to the accumulation of proteins and immune cells at the site of injury or infection, facilitating the body's ability to respond effectively to the threat.

Enhancing the innate immune response by concentrating immune cells in a specific area is essential for a timely response to pathogens. By providing these cells and more fluid, inflammation helps to contain and eliminate the invaders, clear out damaged tissue, and set the stage for the healing process. This mechanism is essential for preventing the spread of infection and helping to initiate further immune responses if needed.
