Match the ANTIBODY class to this description:
Predominant antibody in mucus, saliva, tears and milk
IgA
Match the ANTIBODY class to this description:
Crosses the placenta, giving passive immunity to the foetus
IgG
Match the ANTIBODY class to this description:
The most abundant antibody found in blood plasma and chief antibody released during secondary responses.
IgG
Match the ANTIBODY class to this description:
Binds to the surface of mast cells and mediates an allergic response
IgE
Match the ANTIBODY class to this description:
Virtually always bound to the surface of a B cell; its antigen receptor
IgD
Match the ANTIBODY class to this description:
The first antibody released during the primary response; indicates a current infection
IgM
State whether the following are an example of passive or active immunity:
An individual receives Sabin polio vaccine
Active
State whether the following are an example of passive or active immunity: 'borrowed' immunity
Passive
State whether the following are an example of passive or active immunity:
An individual has chicken pox
Active
State whether the following are an example of passive or active immunity:

cytotoxic cells
Name a characteristic of complete antigens?
reactivity with an antibody
T lymphocytes are produced in the?
Bone marrow
The primary immune response?

True
The directional movement of cells in response to chemicals is called chemotaxis?
