Macrophages play a vital role in the tissue healing process by acting as key players in the immune response and inflammatory phases of healing. They are known for their ability to phagocytize, or ingest, a variety of substances to facilitate the healing process. This includes not only dead cells but also bacteria that may be present at the site of injury. By engulfing and digesting these harmful microorganisms, macrophages help to clear the area of potential infection, which is crucial for proper healing. Additionally, the removal of cellular debris promotes a clean environment conducive to tissue regeneration and repair.

The versatility of macrophages in ingesting both bacteria and dead cells underscores their importance in both the innate immune response and in the transition from the inflammatory phase to the proliferative phase of healing. Hence, their function goes beyond just clearing cellular debris, extending to the maintenance of overall tissue health during the recovery process.
