Definition of the lymphatic system, its components, and its three primary functions: fluid drainage, lipid transport, and immune response.

Description of lymph flow from capillaries to subclavian veins, including the roles of the thoracic and right lymphatic ducts and the muscle/respiratory pumps.

Distinction between primary maturation sites (bone marrow, thymus) and secondary response sites (lymph nodes, spleen, nodules).

Overview of non-specific defenses including physical barriers, internal phagocytes, antimicrobial proteins, inflammation, and fever.

Examination of specific immunity involving T-cells (cell-mediated) and B-cells (antibody-mediated).

How lymphocytes proliferate and differentiate into effector 'soldiers' and long-term memory cells.

The structure of immunoglobulins and their five classes (IgG, IgA, IgM, IgD, IgE) along with their neutralization mechanisms.

Comparing the slow primary response to the rapid, intense secondary response triggered by memory cells.
