Cells that engulf and digest bacteria and other foreign substances  as well as debris from dead cells are called macrophage. Macrophage  also stimulate white blood cells to â¦respond to pathogens.
Instead, the eating machines engulf viruses and bacteria. This is called phagocytosis. First, the macrophage surrounds the unwanted particle and sucks it in. Then, the macrophage breaks it down by mixing it with enzymes stored in special sacs called lysosomes.acrophages are the biggest type of white blood cells-about 21 micrometers-or 0.00083 inches. Still too small to see with your eyes, but big enough to do the important job of cleaning up unwanted viruses, bacteria, and parts of dead cells. Macrophages donât eat cells the same way you might eat your food.
