During the healing process, which cells are primarily responsible for surrounding and removing foreign objects?

• A. Red blood cells
• B. White blood cells
• C. Platelets
• D. Fibroblasts

Answer: (B)

White blood cells take the lead in defending tissue during healing. They migrate to the injury, surround foreign objects or pathogens, and remove them through phagocytosis. Neutrophils are typically the first responders, phagocytosing invaders, with macrophages coming in to clean up debris and continue the process. This immune action is what clears threats and allows repair to proceed. Red blood cells carry oxygen, but don’t remove invaders; platelets focus on clotting to stop bleeding; fibroblasts rebuild tissue by laying down collagen. So the cells responsible for surrounding and removing foreign objects are white blood cells.
