• B) The complement pathway normally functions to clear immune complexes from the circulation.
• C) Complement inhibitory proteins are up-regulated by complement activation.
• D) The complement pathway is part of the innate, rather than the adaptive immune response.
• E) Partial activation of the complement cascade promotes phagocytosis of host cells.
