Question 1

Which of the following statements is INCORRECT?

Accepted Answer

A)  Viruses grow within cells and each type of virus grows in only certain types of cells. 
B)  The role of antibodies and T cells varies on the type of disease and stage of infection. 
C)  Viruses are more easily controlled by the immune system than bacteria. 
D)  AIDS results in a drastic drop in T cells. 
E)  Fungal infections are controlled by T cell responses which leads to the development of resistance.

E)  toll-like receptors.

Question 4

The immune system

Accepted Answer

A)  includes secondary lymphoid organs such as Peyer's patches and the adenoids. 
B)  mounts the strongest immune response at the site of infection although the cells, debris and antigens from this site are eventually carried by the lymphatic vessels to the local lymph nodes where they are simply filtered. 
C)  mounts immune responses at primary lymphoid organs such as the lymph nodes, spleen and tonsils. 
D)  is dependent on lymphatic vessels to filter out foreign organisms and co-ordinate an organised response involving T-cells. 
E)  has secondary lymphoidal tissue that is recruited to an immune response only where an immune memory already exists as a result of a previous or primary infection.

Question 5

Innate defence mechanisms are

Accepted Answer

A)  only relevant to lower organisms as the immune system of mammals has superseded the primitive response. 
B)  the rapid first line of defence against infections in mammals. 
C)  specific, distinguishing clearly between different organisms. 
D)  important in early infection, but decrease once the specific acquired immunity is developed. 
E)  always present, and may be activated if the infection is large.
