    Macrophage engulfing TB bacteria. Computer illustration of a macrophage white blood cell (pink) engulfing tuberculosis (Mycobacterium tuberculosis) bacteria (orange). This process is called phagocytosis. Macrophages are cells of the body's immune system. They phagocytose and destroy pathogens, dead cells and cellular debris.
