Name: date: Period: Innate Immunity worksheet (1) From the word bank, assign each term to the immunity heading with which it is associated. Some terms may fit more than one category and should be placed in all categories that apply. antibodies in breast milk lymphocytes stomach acid, saliva, tears complement first line of defense Passive immunity generalized response specific memory non-specific same response every time cellular response short-lived antibodies variable response barriers Innate immunity Adaptive immunity (2) The two types of phagocytes associated with the innate immune response are __________________ and ___________________. List the functions of each: ________________________________ _____________________________________________ (3) Nail biters often have red, warm, and swollen areas around the cuticles. What kind of response does this condition indicate? ____________________________ Explain specifically why the area is red; why it is warm; and what causes the swelling. _____________________________________________________________________ _____________________________________________________________________ _____________________________________________________________________ _____________________________________________________________________ _____________________________________________________________________ _____________________________________________________________________ Answer Key (1) Passive immunity antibodies in breast milk short-lived antibodies Innate immunity Adaptive immunity barriers complement lymphocytes cellular response generalized response same response every time non-specific first line of defense stomach acid, saliva, tears antibodies in breast milk complement lymphocytes memory specific variable response (2) Two types of phagocytes : macrophages - ingest pathogens and dead cells neutrophils - release chemicals that kill nearby bacteria (and themselves) (3) Nail biters: Inflammatory response causes: redness and warmth - increased blood flow to the area, bringing phagocytes swelling (edema) - fluids leaking from plasma into intercellular spaces, phagocytes engulf pathogens
