Exam 33: Adaptive Immunity

The part of the antibody that combines with the antigen is the:

Memory cells do not actually produce antibodies.

Specific immunity is controlled by two classes of lymphocytes called:

The predominant antibody of a secondary response is:

Explain how complement is activated and can produce cytolysis in the process of humoral immunity.

Systemic lupus erythematosus is an example of a(n):

The cloning of T cells produces both memory cells and plasma cells.

In humans, bursa equivalent tissue is the site for B-cell development.

All antigens have epitopes of the same shape.

When antibodies cause antigens to agglutinate, it allows them to be disposed of by phagocytes more easily.

The immune mechanism that provides a defense by acting against cancer is termed nonspecific immunity.

Chris has very bad allergies, especially in the springtime, and is seeking help to overcome her allergic reactions. Why would an antihistamine help Chris be more comfortable?

The antibody normally constituting the highest percentage of antibodies in the blood is:

Unlike B cells, T cells do not display antigen receptors on their surface membranes.

Inactive B cells produce antibodies that insert on their plasma membranes to serve as antigen receptors.

Suppressor T cells help B cells differentiate into antibody-secreting plasma cells by secreting cytokines such as interleukin-2 and interleukin-4.

One of the antigen-specific sites on the antibody is used to activate the complement cascade in the blood.

A mother passes antibodies to her baby

A person gets a flu shot to keep from getting the flu

In the first stage of their development, B cells are known by all the following terms except _____ B cells.
