Image 1: A representation of a macrophage engulfing a bacteria Macrophages are specialised cells responsible for protecting the human body from foreign harmful organisms. These cells are responsible for detection, phagocytosis, and killing bacteria. They attack the bacteria by ingesting it inside, which then gets trapped inside the phagosome. Within the phagosome the enzymes and toxic peroxides digest the pathogen.
