Antigen Antibody Complex Pathogens Toxins Describe Explain Ways Antibodies

The summary explains four ways antibodies defend the body: as opsonins, preventing host cell invasion, as agglutinins clumping pathogens, and as anti-toxins neutralizing toxins.

O resumo explica quatro maneiras pelas quais os anticorpos defendem o corpo: como opsoninas, impedindo a invasão de células hospedeiras, como aglutininas que agrupam patógenos e como antitoxinas que neutralizam toxinas.

Front Describe and explain 4 ways in which antibodies defend the body.
Back Function of antibodies:
  • Opsonins - antigen-antibody complex easily engulfed and digested by phagocytes
  • Pathogens can no longer effectively invade host cells when they are part of antigen-antibody complex
  • Agglutinins - cause pathogens carrying complexes to clump together - prevents them from spreading and easier to engulf multiple at same time
  • Anti-toxins - make toxins harmless
