Medical dictionaries and encyclopedias are not to be included as one of the two minimum references.  Writing and Math Centers

Seminar Topics Lymphatic System  Primary Structure  Generalized functions Types of Immunity  Non-specific vs. Specific  Natural vs. Artificial  Active vs. Passive Immune System  Antibodies  Complement  Phagocytes  Lymphocytes Page 338

Lymphatic System Lymph Fluid Lymph Vessels  Contain valves Lymph capillaries  Contain blind end  Called lacteals in intestinal wall Page 339

Lymphatic System Right Lymphatic Duct  Drains lymph from the right upper extremity and right side of head, neck, and upper torso Thoracic duct  Drains lymph from about three-fourths of the body  Cisterna Chyli Page 340

Case Study Often after the surgical removal of a breast, lymph nodes, and lymphatic vessels—especially those in the upper arm—swelling occurs. What is the physiological reason swelling takes place? Why is removal of the axillary lymph nodes helpful?

Lymphatic System Lymph nodes  Filter lymph  WBC formation Thymus  Produce T-cells Tonsils  Filter bodily fluids (saliva) Spleen  Phagocytosis  Blood Reservoir

Types of Immunity Non-specific Immunity  Skin, tears, mucous membranes Specific Immunity  Natural Immunity  Active vs. Passive  Artificial Immunity  Active vs. Passive

Immune System Antibodies  Neutralize toxins  Clump or agglutinate enemy cells  Promote phagocytosis Page 346 Complement (Page 347) Phagocytes  Neutrophils  Monocytes  Macrophages  Kupffer Cells  Dust Cells
