Document Content and Description Below

1 — Lymphatic System Identify the major structures and function of the lymphatic system. Which of the following is a function of the lymphatic system?  a.) Circulating nutrients to various organs  b.) Sending signals from the brain to the extremities  c.) Returning excess fluid to the circulatory system  d.) Pumping blood through the body 2 — Pathogens Determine how the human body protects itself from pathogens. Which of the following statements about innate immunity is true?  a.) Innate immunity involves a targeted response against pathogens the body has fought before  b.) Innate immunity describes how physical barriers prevent many pathogens from entering the body  c.) Innate immunity is a generalized response that does not target specific pathogens  d.) Innate immunity means a type of pathogen doesn't have any effect on the human body 3 — Innate Immunity Identify the characteristics of the body's second line of defense against pathogens. A fever is an example of what kind of defense against pathogens?  a.) Adaptive immunity  b.) Innate immunity  c.) All answer choices are correct  d.) Physical barriers 4 — Adaptive Immunity Identify the characteristics of the body's third line of defense against pathogens. Which of the following is a characteristic of adaptive immunity?  a.) It involves the complement system, which causes damage to pathogens.  b.) It relies on lysosomes to break down pathogens.  c.) Innate immunity is one type of adaptive immunity.  d.) It comes into play once a pathogen gets past the body's more general immune responses. 5 — Humoral Immunity Understand an antibody-mediated immune response. Which set of facts is true for humoral immunity?  a.) It is an adaptive response. it is mediated by T-cells in the thymus.  b.) It is a non-specific response. It is mediated by macrophages.  c.) It is an adaptive response. It is mediated by B-cells in lymph nodes.  d.) It is an innate response. It is mediated by B-cells in lymph nodes. 6 — Cell-Mediated Response Identify characteristics of a cell-mediated immune response. What is apoptosis?  a.) Death of a cell from old age  b.) The intentional death of a cell  c.) The accidental death of a cell  d.) Death of a cell after dividing 7 — Organ Transplant and Immunotherapy Determine why a persons body might either accept or reject a transplanted tissue or organ. Which cells would be activated in response to the drug Herceptin being added to a cell containing HER2 protein?  a.) Natural killer cells  b.) Myeloma cells  c.) Memory cells  d.) Spleen cells 8 — Vaccines Understand how a vaccine can be used to prevent certain diseases. Which of the following statements about vaccines is true?  a.) A vaccine marks invading viruses the body wouldn't otherwise notice for destruction.  b.) Vaccines prevent the production of memory cells, making it difficult for disease to spread.  c.) Vaccines use dead or weakened antigens to produce antibodies, known as active immunity.  d.) A booster shot is used to elicit a primary immune response in which the body produces antibodies against a particular pathogen.
