Describe 3 different ways that antibodies inactivate antigens

1) Antibodies are produced into the blood and mucosa, there they bind to and inactivate substances like pathogens and toxins. It's pretty much neutralization.

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

3) Antibodies facilitate phagocytosis of other substances by phagocytic cells (opsonization).
