Concept explainers
To review:
Match the term antibodies with the most closely related description given below:
Rapid secondary response.
Responsible for cell-mediated immunity,
Produce antibodies.
Aid in immune surveillance.
Contains developing T cells.
Immunoglobulins.
Responsible for antibody-mediated immunity.
Production of lymphocytes.
Saclike chamber of the thoracic duct.
Largest lymphatic organ in the body.
Introduction:
Antibodies are the molecules, which are released by the plasma cells (a differentiated form of the B cells) and generate the humoral response in the individual. The antibodies are specific for the antigen molecules. The interaction between the epitope of the antigens and paratope of the antibody results in the generation of the immune response by the antibodies.

- 1. The laboratory scientist who reviews the marrow reports that the bone marrow is overridden with plasma cells—so much so that clusters of plasma cells can be seen. What is the function of plasma cells? Explain with no more than 3-6 sentences. A). To present foreign antigens to immune cells B). To directly attack foreign cells when foreign antigens are recognized. C). To phagocytize cells with foreign antigens. D).
