Phagocytes: Your Body's Cellular Clean-Up Crew

A phagocyte is a type of white blood cell that ingests and destroys foreign particles—bacteria, viruses, dead or damaged cells. Major types include:

  • Neutrophils: Most common; first responders to infection.
  • Macrophages: Reside in tissues; remove dead/damaged cells and foreign debris.
  • Dendritic cells: Located in skin and mucosa; capture and present antigens to the immune system.
