Caption: Phagocytic cells involved in phagocytosis of E. coli -the filopodial type is a macrophage and the lamellar type is a monocyte. These cells are part of the hematopoietic / reticuloendothelial system. A macrophage is a large, mature phagocyte that can ingest and destroy invading microbes, foreign particles, cancerous or diseased cells and cellular debris. A monocyte is a circulating phagocyte that ingests microbes, invading particles, and cellular debris. Monocytes mature into macrophages and are both part of the reticuloendothelial system.
