Phagocytosis is the process by which cells engulf particulate material such as bacteria or cellular debris. Actin-containing microfilaments are responsible for the formation of pseudopods, which extend around the material and ultimately fuse to form a phagosome. This process is driven by the dynamic polymerization and depolymerization of actin filaments, which allows for the extension and retraction of pseudopods. Tubulin-containing microtubules are not directly involved in the process of phagocytosis. Myosin-containing microfilaments are involved in muscle contraction, but not in phagocytosis.
