Quizplus · Accepted Answer

All of these events occur subsequent to the invasion of bacteria into a wound. Complement activation results in the formation of membrane attack complexes that can directly kill bacteria or attract phagocytes to the site. Bacteria can be captured by lymph nodes for further processing and identification by immune cells. Bacteria can also bind to B cells and stimulate the production of antibodies. Finally, the chemotactic factors secreted by the bacteria, such as bacterial peptides and complement fragments, can attract phagocytes to the site of infection to engulf and destroy the bacteria.
