Phagocytes A type of white blood cell the "eats" dead cells, and other "debris" in the blood.
----------------------------- A phagocyte is a white blood cell that 'engulfs' not only dead cells and debris but also reacts against Pathogens (disease causing micro-organisms). There are different types of phagocytes e.g. Macrophages or Neutrophils.
The process where a Phagocyte 'disposes' of a pathogen is called phagocytosis, when a bacteria attaches to a phagocyte, using ligands, The phagocyte forms Pseudopods (cytoplasmic arms) that envelope the pathogen, the Psuedopodia then fuse, creating a membrane, enclosing the pathogen forming a phagosome, this moves deeper within the cell to then form with a lysosome forming a phagolysosome (not really imaginitive naming i know, but scientists aren't known for their imaginative naming ). the lysosome contains enzymes (you guessed it, lysozyme) the lysozyme destroys the bacterial cell walls allowing hydrolytic enzymes to digest the rest of the pathogen.
