How do antibodies fight pathogens

1) Antibodies are secreted into the blood and mucosa, where they bind to and inactivate foreign substances such as pathogens and toxins (neutralization).

2) Antibodies activate the complement system to destroy bacterial cells by lysis (punching holes in the cell wall).
