Body Defenses and the

Immune System

Nonspecific Defenses Learning Objectives
Specific Immune Response
B Lymphocytes • Define and be able to explain the signifi-
Immunoglobulins cance of the bold italic terms in this
chapter.
T Cells and Cell‐Mediated Immunity • Define the concept of immunity and
Lymphocyte Origin, Development, generalize the mechanisms by which an
and Residence animal can mount nonspecific versus
Active and Passive Immunities specific defenses to foreign substances.
Immunological Surveillance • Compare and contrast the location
Lymphatic System and function of each of the different
immunoglobulins.
Lymphatic Vessels • Compare and contrast the location and
Lymph Nodes function of each of the major structures
Spleen of the lymphatic system.
Thymus • Illustrate the differentiation of lymphoid
Tonsils stem cells in the three general classes of
lymphocytes. Be sure to include how
this maturation process also dictates
function in the mature cell.
• What is lymph and why does it need to
be filtered?
• What is the direction of flow within the
lymphatic vessels and how does it con-
tribute to immunologic surveillance?
For example, an infection in the distal
hindlimb versus distal forelimb – which
would result in an enlarged popliteal
lymph node?
