The primary cells involved in an inflammatory response are white blood cells, also known as leukocytes. These cells play a critical role in the body's defense mechanisms against infections, injuries, and foreign invaders. During an inflammatory response, white blood cells are mobilized to the site of injury or infection, where they perform several essential functions.

For instance, neutrophils, a type of white blood cell, are among the first responders and are effective at phagocytizing bacteria and debris. Other types of white blood cells, such as lymphocytes and macrophages, contribute to the immune response by producing antibodies and releasing signaling molecules (cytokines) that help regulate the inflammation process.

The role of white blood cells in inflammation includes not only the direct attack on pathogens but also the orchestration of the overall immune response, which involves communication with other immune cells, the activation of the adaptive immune system, and the removal of harmful stimuli.

In contrast, red blood cells primarily function to transport oxygen and carbon dioxide, while platelets are mainly involved in blood clotting and hemostasis, rather than in the inflammatory response itself. Fibroblasts, though important in tissue repair and regeneration, are not primarily involved in the initial inflammatory reaction but rather
