In which of the following does the blood clot appropriately to prevent major blood loss? • Hemophilia • Embolism • Hemostasis • Thrombosis CONCEPT Platelets 2 What is the role of the aorta in the systemic circuit? • It supplies deoxygenated blood to various body tissues. • It supplies oxygenated blood to various body tissues. • It collects oxygenated blood supplies from the lungs. • It collects deoxygenated blood supplies from the lungs. CONCEPT Heart and Blood Flow 3 Which antibody that inhibits pathogens from binding to the body's cells is found in endocrine gland secretions, such as tears and saliva? • IgD • IgG • IgA • IgE CONCEPT Humoral Immunity 4 What might a person with chronically low blood pressure be diagnosed with? • Vasoconstriction • Hypertension • Hypotension • Vasodilation CONCEPT Blood Pressure 5 What kind of immunity involves white blood cells that have receptors for specific pathogens that changes over time and produces memory cells? • Adaptive • General • Pathogenic • Innate CONCEPT Pathogens 6 Which type of white blood cell attacks other unhealthy cells? • Monocytes • Eosinophils • Basophils • Lymphocytes CONCEPT White Blood Cells 7 What are the antibodies found in blood type B? • Anti-B • Neither anti-A nor anti-B • Anti-A and Anti-B • Anti-A CONCEPT Blood Types 8 If a transplanted organ's MHC cells don't match those of the recipient, what will happen? • The organ will change its MHC cells so as to be recognized by the recipient's immune system. • The recipient's body will block off the new organ and it won't function normally. • The recipient's immune system will change the MHC markers on the organ so that it won't be identified as an intruder. • The recipient's immune system will identify the transplanted organ as an intruder and attack it. CONCEPT Organ Transplant and Immunotherapy 9 Which of the following statements about vaccines is true? • A vaccine prompts the body's T-cells to produce antibodies against the virus. • Vaccines are non-specific, meaning they protect against a variety of viruses or illnesses. • Booster shots are a type of secondary vaccine that allow for longer lasting protection against a particular virus. • Vaccines are used against viruses, bacteria and fungal infections. CONCEPT Vaccines 10 What muscular tubes, not supported by cartilage, help regulate airflow into and out of the lungs? • Diaphragm
