They break down the pathogens that enter the body

Explanation:

Macrophages are the first line of defense .They engulf any pathogen that gets in their way in a process called phagocytosis

Phagocytosis

When the macrophages ingest the pathogen ,the cell membrane surrounds the pathogen to form a vesicle known as a phagosome Later this phagosome is combined with a lysosome ,which is a vesicle containing digestive enzymes to form phagolysosome.The digest enzymes in the lysosomes breaks the pathogen down.
