Name: ________________________ Date: ______________ Per: ______ Major Players in the Immune System Draw how the nonspecific defense works when a pathogen enters the body. Label the players. Draw how the specific defense works when a pathogen enters the body. Label the players. Non-Specific Defenses Player Name Function Analogy Explanation Viruses, bacteria, fungus, etc. (microorganisms) that cause infectious diseases Sticky or acidic fluid that traps pathogens and kills them Dry flexible covering over your whole body that keeps out pathogens White blood cells that attack and destroy pathogens entering the body Identifying “tags” on the surface of invading pathogens Eats/destroys pathogens and saves identifying antigens to alert other white blood cells to start the immune response Immune Response Receives signal from the macrophage and recruits Tcells and B-cells to infected area Kills infected body cells to prevent the further spread of an infection Makes antibodies specific to a particular antigen found on a pathogen A protein produced to tag an antigen for attack by other cells; each one is specific to one antigen Sends the signal to slow down the immune response once pathogens are under control Cells that are made to remember the antigen and remain in the body in case of another infection *Extra Credit: Create an analogy for each “player” of the immune system. Explain why your analogy fits.
