A) Put the steps in activation of cellular immunity inthe correct order:

1. infected cells are apoptosed

2. cytotoxic T cell is activated

3. it becomes an APC

4. phagocyte encounters antigen

5. helper T cell is activated

B) match each term with its function in normal immunity:

1.cytotoxic T lymphocytes 2. interferons 3. helper T lymphocytes 4. pyrogens 5. plasma cells 6. interleukins 7. NK cells 8. tumor necrosis factor (TNF) 9.dendritic cells 10. colony stimulating factor (CSF) 11.antibodies 12.phagocytes

A. re-set the body's \"thermostat\" to a higher temperature

B. small proteins produced by infected cells that slow the spreadof viral infections

C. stimulate specific responses of both B cells and other Tcells

D. non-specifically attack foreign cells, cancer cells, andinfected cells

E. stimulate blood-cell-producing colonies in red marrow andlymphocyte-producing colonies in lymphoid tissues

F. produce and secrete antibodies

G. another type of cell, besides macrophage, that become APC's

H. specifically attack and destroy foreign cells or infectedcells

I. carry messages between leukocytes and from leukocytes to thebody

J. attach to pathogens, starting a chain of events that leads totheir destruction

K. attack, \"eat\", and destroy foreign substances or pathogens

L. multi-purpose immune stimulants named for their tumor-fightingactivity but also important in stimulating nonspecific immuneactivity
