  1. Which of the follow is not a nonspecific defense against pathogens:

a.       Tears

b.      Inflammation

c.       Macrophage

d.      Lymphocytes

 

  1. T-cells would not bind to pathogen because:
    1. Pathogens do not have antigens
    2. Pathogens do not have MHC
    3. Pathogens do not have phagocytic cells
    4. B-cells, not T-cells, are supposed to bind to pathogen

 

  1. Cells made in bone marrow are called __________, and cells made in the thymus are called ___________.
    1. Lymphocytes, phagocytes
    2. Pathogens, antigens
    3. B-cells, T-cells
    4. MHC, antibodies

 

  1. Long-term resistance to an encountered pathogen is also known as:
    1. Immune memory
    2. Adaptive immunity
    3. Clonal selection
    4. A nonspecific defense

 

  1. Your body is recognizing your own proteins as foreign. IT Is
    1. building tolerance
    2. commiting self-tolerance
    3. building auto-immunity against itself
    4. under HIV infection

 

  1. True or False.  It is not okay to suppress hypersensitivities to dust with antihistamines because it is ignoring an important reaction.

 

  1. There are 100 light chains and 100 heavy chains for the building of antibodies.  There are a possible 10,000 combinations.  If their were 10 light chains and 100 heavy chains how many possible combinations are there?

 

    1. 100
    2. 1,000
    3. 10,000
    4. this is not possible

 

  1. When does your body build enough antibodies for immunity under the vaccination process.
    1. under the first antibody response to foreign cells
    2. the second immune response to foreign cells
    3. it will always have to build more antibody continuosly until the virus is not considered foreign
