Immunology

A small injected dose of a pathogen that stimulates the production of antibodies is:

• histamine
• interferon
• pathogen
• vaccine

A type of cell that "digests" pathogens is known as a/an:

• helper T cell
• macrophage
• suppressor T cell
• plasma cell

This reaction may cause sneezing, watery eyes, and cough in response to a foreign substance:

• immune response
• allergic response
• interferon response
• None of the above responses are correct

• respiratory
• digestive
• integumentary

_______ are large cluster of lymphatic cells found in the pharynx

• adenoids

• thymus

• lymph nodes

• tonsils

An inflammation reaction involves the

• release of histamines.

• agglutination of bacteria.

• production of immunoglobulin.

• vaseconstriction of blood vessels.

The graph shows the antibody levels in the blood after a person has been exposed twice to the same pathogen. With regard to this pathogen we can conclude that

• the person has a deficient immune response.

• the virulence of the pathogen increased between the first and second exposures.

• antibodies are only produced after a second exposure to the pathogen.

• memory cells for antibodies against the pathogen exist at the time of the second exposure.
