The engulfment of particulate material by phagocytosis is driven by the contractile activities of the actin-containing microfilaments that underlie the plasma membrane. These microfilaments are responsible for extending pseudopods around the material to be engulfed and then bringing them back together to form a phagosome. Once the phagosome is formed, it can then fuse with lysosomes for degradation of the engulfed material.
