1. List all components of the first line of defense and describe how they protect the body. 2. Describe all components of the second line of defense and describe how they protect the body. 3. Below you find a representation of a cytotoxic T cell, helper T cell, and B lymphocyte. Show what each cell can see and make sure to include in drawing: APC cell, infected body cell, MHC class 1 w/ antigen, MHC class II w/ antigen, T cell receptor, CD4 protein, CD8 protein, IgD antibody.

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. Mucus & cilia 26-27. basophils & mast cells 28-30. Complement proteins: list the function for each set of complement proteins below 28. C5-C9 29. C3b 30. C3a and C5a
