Name______ Immune System Date________ 1. Which row in the chart below contains an event that is paired with an appropriate response in the human body? A) (1) B) (2) C) (3) 2. A series of enzyme-controlled reactions that occur when platelets rupture is known as A) passive immunity C) asthma B) blood clotting D) anemia D) (4) 7. The diagram below represents one type of white blood cell. This type of white blood cell ingests microbes. 3. A direct indication that the white blood cells of the body are functioning would be A) an increase in the number of oxygen molecules in the lungs B) a decrease in the number of pathogens in the body C) a decreased secretion of hormones by certain glands D) an increase of carbon dioxide in the cells of the body 4. Cells of the immune system are able to respond to the presence of invading organisms because they recognize the A) B) C) D) antigens present on the invaders antibodies present in invading pathogens DNA pattern in the nuclei of viruses antibiotics released from microbes A function of another type of white blood cell is to A) prevent the loss of blood from a wound B) produce specialized molecules that mark invaders C) increase the number of red blood cells in the blood D) cause gene mutations that will increase immune responses 8. Which diagram best represents a blood cell from a person with type O blood? 5. An infection in the body might result in a sudden A) decrese in the activity of antigens produced by the mitochondria B) decrese in the amount of DNA present in the nuclei of cells C) increase in the activity of white blood cells D) increase in the number of red blood cells 6. A dead or weakened pathogen used to establish immunity would most likely be found in A) a pesticide C) a vaccine A) B) C) D) B) an antibiotic D) a toxin Page 1 9. The two reactions illustrated in the diagrams below often occur when a foreign substance enters the body. The cells labeled A and B are examples of cells known as A) guard cells C) white blood cells B) reproductive cells D) specialized skin cells 10. Base your answer to the following question on the information and diagram below. A technician needed to determine the blood type of four individuals. To do this, the technician set up four slides, one for each individual. The technician placed a drop of antibody A serum and a drop of antibody B serum on each of four slides. The technician mixed a drop of blood from each individual into the anti-A and anti-B serum on a different slide. The results of the four tests are shown below. Which slide contains blood from the individual who has antigen A, but not antigen B? A) 1 B) 2 C) 3 D) 4 Page 2 Base your answers to questions 11and 12 on " the blood-typing chart below and on your knowledge of biology. " 11.Individual 1 has blood type A) A B) B C) AB D) O 12. Which antibodies, if any, are in the plasma of individual 2? A) anti-A, only C) both anti-A and anti-B B) anti-B, only D) neither anti-A nor anti-B 13. A student received a flu shot in the fall. During the flu season, the student caught a cold. The most likely reason the vaccine he received did not prevent the cold was that A) his illness was not caused by a pathogen B) he did not get the vaccine at the right time of year C) his body produced antibiotics in response to the vaccine D) the vaccine he received contained only flu virus antigens 15. A student infected by a common cold virus ran a low-grade fever. After a few days, the student's temperature returned to normal and the student was free of cold symptoms. The fever served as A) B) C) D) an antigen in the circulatory system an immune response to a pathogen a biological catalyst a weakened pathogen 16. Every time a child visited a cousin who has two cats, the child's eyes turned red, itched, and began to water. Then, the child began to have trouble 14. An organ, such as a kidney, used for transplant needs breathing. It is most likely that the child reacted this to be tested for compatibility with the person who is way because to receive the organ. If this is not done, the A) normally harmless cat antigens stimulated the A) donated organ might attack the body immune system B) donated organ might attack the immune system B) it is difficult for the respiratory system to filter cat antigens out of the inhaled air C) immune system might attack its own body cells C) cat antigens are a health hazard, since they D) immune system might attack the donated organ always cause disease D) cat antigens stop the immune system from making antibodies, so bacteria cause these responses Page 3 17. An allergic reaction to certain types of natural, unprocessed foods, such as peanuts, is caused by A) B) C) D) 20. An activity that occurs in the human body is shown below. a lack of digestive enzymes a response to specific antigens microorganisms living within the food high levels of carbon dioxide in the air 18. Responses of the immune system to usually harmless environmental substances are known as A) B) C) D) antigen production chromosomal mutations pathogens allergies 19. A 6-year-old child ate a peanut butter sandwich at snack time in school. Five minutes later, her throat became swollen and she collapsed. This allergic reaction occurred because her body A) recognized an antigen in peanut butter and produced antibiotics against it B) digested the white blood cells that can recognize an antigen in peanut butter C) did not recognize an antigen in peanut butter and could not produce antibodies against it D) recognized an antigen in peanut butter and produced an immune response This activity helps to A) B) C) D) provide protection against pathogens produce antibiotics to control disease eliminate harmful gene alterations regulate production of ATP by the cell Page 4
