Which of the following are part of innate immunity's second line of defense? Choose all that apply. Select one or more: a. lymphatic structures and fluid b. antimicrobial substances such as complement, interferon, and iron-binding proteins c. fever d. inflammation e. White blood cells, especially phagocytes 3. _____________________ is a dual system that involves cell-mediated immunity and humoral immunity; vaccines will stimulate this.
