  B)
  Vasoconstriction
  C)
  Migration of phagocytic white cells
  D)
  Macrophage activity

Question 2

A student states, It seems like helper T cells do a lot more than just 'help' the cellular immunity process. Which of the following responses listed below best conveys an aspect of the role of CD4+ helper T cells in immunity?
 
  A)
  Without helper T cells, no antigens would be presented.
  B)
  Helper T cells play a major role in stimulating and regulating the whole process.
  C)
  Without helper T cells, the wrong antibodies would end up being produced.
  D)
  Helper T cells are key to the hematopoiesis that produces all the components of the immune system.

Answer to Question 1

Ans:
B

Feedback:

While vasoconstriction is a component of the immediate inflammatory response, the later cellular phase of inflammation is accompanied by vasodilation. Platelet aggregation, vasoconstriction, migration of phagocytic white cells, and macrophage activity are all associated with the cellular phase.

Answer to Question 2

Ans:
B

Feedback:

Helper T cells are central to the regulation, proliferation, and stimulation of the immune system. They do not play a central role in antigen presentation or early hematopoiesis, however. Their absence would not result in incorrect antibody production, but rather insufficient or absent immune response.
