1. In phagocytosis, the digestion of phagocytes is always complete 2. The second line of defense is a specific immune response that responds against a specific type (species or strain) of pathogen. 3. Eosinophils can phagocytize and this is their usual mode of attack. 4. The body’s initial line of defense is made up of chemicals, and processes that work together to prevent pathogens from entering the body in the first place. 5. In general, beta and gamma interferons are present early in viral infections, whereas alpha interferon appears somewhat later in the course of infection. 6. The second line of defense is chiefly composed of external physical barriers to pathogens, especially the skin and mucous membranes. 7. The chemicals involved assist phagocytic cells either by directly attacking pathogens or by enhancing other features of specific resistance. 8. The combination of the barrier function of the dermis including its continual replacement and the presence of phagocytic…
