Transcript
Name _____________________________ Date _________________ Period _________ Place selfgrade here Section 37.2 The Immune System Before you read the section, fill out the triple entry vocabulary journal (chart below) 1 point for definition, one point for picture, memory aid, phrase or sentence. Word in Context One method of defense is phagocytosis. . . the process by which phagocytic cells surround and internalize the foreign microorganisms. (p. 1085) Complement proteins enhance phagocytosis by helping the phagocytic cells bind better to pathogens, activating the phagocytes and enhancing the destruction of the pathogen’s membrane, . . . (p. 1085) Virus-infected cells secrete a protein called interferon. (p. 1085) Lymphocytes are a type of white blood cell that is produced in red bone marrow. (p. 1086) Antibodies are proteins produced by B lymphocytes that specifically react with a foreign antigen. (p. 1086) B lymphocytes, often called B cells, are located in all lymphatic tissues and can be thought of as antibody factories. (p. 1086) Page 1 Definition in your OWN words Picture, Memory Aid, Phrase or Sentence Word in Context Definition in your OWN words Picture, Memory Aid, Phrase or Sentence In the lymphatic tissues, such as the lymph nodes, the macrophage, with the processed antigen on its surface, binds to a type of lymphocyte called a helper T cell. (p. 1088) Activated cytotoxic T cells destroy pathogens and release chemicals called cytokines. (p. 1088) Memory cells are long-living cells that are exposed to the antigen during the primary immune response. (p. 1089) Immunization, also called vaccination, is the deliberate exposure of the body to an antigen so that a primary response and immune memory cells will develop. (p. 1089) While you read pages 1084 to 1091, fill out the foldable that you created with the directions on page 1075. Be sure to USE the vocabulary words from the front page of this handout. After reading, answer 3 of the 6 questions: 1. Compare specific and nonspecific immune responses. 2. Describe the steps involved in activating an antibody response to an antigen. 3. Make an illustration demonstrating passive and active immunity. 4. Describe the structure and function of the lymphatic system. 5. Why is the destruction of helper T cells in HIV infection so devastating to SPECIFIC immunity? 6. Compare the role of helper T cells and cytotoxic T cells in the specific immune response.
