In phagocytosis, what happens after the phagosome forms?

After a phagosome forms, it fuses with a lysosome to form a phagolysosome. In this fused compartment, lysosomal enzymes such as proteases, nucleases, and lipases, along with an acidic environment established by proton pumps, break down the phagocytosed material. The oxidative burst can also help kill ingested pathogens. The digested contents are then processed into usable molecules or antigens, while any indigestible material may be expelled or stored as a residual body.
