The engulfed bacteria is called phagosome and phagosome then fuse with lysosome making phagolysosome. Now fused lysosome secrete lytic enzymes like proteases, lipases and glycosidases which kills the engulfed bacteria by digesting them.
So neutrophils will be the first cells migrates to prevent bacterial infection in the hand of 20 year old boy who shoots his hand with nail gun.
