What is the primary function of WBCs during inflammation?

• A. Transport oxygen to the site of injury
• B. Promote healing and manage the inflammation process
• C. Release inflammatory mediators
• D. Aggregate to block off injured areas

Answer: (B)

The primary function of white blood cells (WBCs) during inflammation is to promote healing and manage the inflammation process. WBCs are integral to the immune response, and their actions are central to resolving inflammation and initiating the healing of tissues.

When tissue injury occurs, WBCs are recruited to the site through various signaling molecules and chemokines. Once there, they perform numerous functions such as phagocytosis of pathogens and debris, activation of other immune cells, and the production of cytokines that help orchestrate the inflammatory response. Additionally, they aid in tissue repair by secreting growth factors and other mediators that promote healing and restore homeostasis.

While WBCs also release inflammatory mediators and can aggregate to prevent further injury, their overarching role encompasses the management of inflammation and facilitating healing, making that the most comprehensive answer regarding their primary function during the inflammatory response.
