Where in the body are lymph nodes found? In the neck, axilla and groin areas.
How many lymphatic ducts are in the body? Two - the right lymphatic duct and the thoracic duct.
Where is the Right Lymphatic Duct located and what does it do? Recieves lymph for the right arm, head and right side of the thorax. It drains into the right sublcavian vein.
Where is the Thoracic Duct located and what does it do? Recieves lymph for the left arm, left side of the head, thorax and both sides of the body below the diaphragm. It drains in to the sublcavian vein.
Where is the spleen located? Left Upper Quadrant.
What is the largest lymphatic organ? The spleen
What types of tissue does the spleen contain? White pulp and Red pulp
White pulp Produces T and B cells. Monitors blood for antigens and produces antibodies.
Red pulp A reservoir for erythrocytes, platelets and macrophages
What is the function of the spleen? Phagocytize bacteria, initiate an immune response, phagocyzite old and defective erythrocytes and to serve as a reservoir.
Tonsils Two masses of lymphatic tissue at the enterance to the oropharynx. It traps inhaled and digested pathogens.
Adenoids Similar to tonsils. Located on posterior wall of the nasopharynx
Thymus Has boh endocrine and lymphatic functions. Reaches maximum size a puberty.
T Cells (T lymphocytes) (Thymus Cells) Make up 75 to 85% of body lymphocytes. Includes: Cytotoxic T cells, Helper T cells, Memory T cells and Suppressor T cells.
B Cells (B lymphocytes) Also called plasma cells. Mature in the bone marrow. Make up 15 to 25% of lymphocytes. Produce antibodies.
Null Cells Large natural killer cells
Macrophages Performs phagocytes
Enlargement of nodes Indication of disease or infection in the tissue
Lymphadenitis Whe lymph nodes are swollen and tender to the touch(infection)
Tonsillitis Inflammation of the tonsils and adenoids

anaphylactic Immediate severe allergic response
hypersensitivity Exaggerated abnormal reaction to an allergen.
anaphylaxis Immediate severe allergic response
What are the three lines of defense against pathogens? Physical mechanisms, Cellular Mechanisms, and Humoral Mechanisms
Splenectomy Surgical removal of the spleen.
Asthma Episodes of breathing difficulty due to narrowed or obstructed airways
autoimmune Immune reaction directed against a persons own tissue
Immunodeficiency Failure of the immune system
What are the classes of Immunodeficiency disorders? Congential, Immunosuppression and acquired immunodeficiency(HIV/AIDS)
Immune system A group of specialized cells, verses an organ system. Has 3 characteristics that include Specificity, memory and discrimination.
What are the two types of immunity? Cellular and Humoral
Types of Immunoglobulins igG,igA,igM,igD, and igE
What are the four classes of Immunity? Natural active, artificial active, natural passive, and artificial paasive immunity
What four functions do antibodies have? Neutralization, agglutination, precipitation and complement fixation.
