Identify which line of defense each component belongs to! Also provide a brief (1 sentence) description of what each part's function. For help, see Ch 14 Lessonbuilder tutorial & pages 1-22 in Unit 3 handout 1st Line or 2nd line? Function (Provide a Brief 1 Sentence Description) Skin (epidermis) 1st line Dead, outermost layer of skin that acts as a physical barrier to prevent the entry of microbes 12-13. eosinophils 14-15. IL-1 & fever 16-17. Mucosal membranes (epithelial cells) 18-19. Lysozyme in saliva & sweat 20-21. IL-6 & inflammation 22-23. macrophages & neutrophils 24-25.

Classify each item as a first, second, or third line of defense. First line of defense: - Humoral immunity - Mucosal membranes - Skin - Cell-mediated immunity - Vaccines - Antibodies - APCs Second line of defense: - Macrophages - Eosinophils - Inflammation - Fever - MHCs Third line of defense: - Lymphocytes - Skin - Humoral immunity - Cell-mediated immunity - Antibodies - Fever
Identify and circle all the FALSE statements (1.2 point) A) Second line of defense is innate and specific. B) Chemical response of our mucous membranes is a part of the second line of defense. C) T- and B- cells are activated by our second line of defense D) Unlike Blood, Lymph is flowing in one direction only. E) Lymph is acting as ‐drain-off" system for inflammatory response. F) T- and B- cells are involved in a number of non-specific cellular responses to a pathogen.
