How would one dive the 3 main structural components and what would be characteristics of each
Lymphatic vessels-one way system toward heart
Lymph nodes-filtering system
Lymphoid tissue & organs-filter out debris, spleen, makes t-cells, thymus gland
What are the main functions of the lymphatic system
Transports fats and fat-soluble vitamins to digestive system

Lymphatic organ and functions
Tonsils-gather and filter out debris

Spleen- controls quality of rbc by killing old ones
Peters patches-macrophages that kill bacteria
Physical and chemical barriers
Skin Tears Urination Mucus Earwax Saliva
How do phagocytes work
Engulf foreign material into vacuoles
Enzymes from lysosomes digest the material
Cell-mediate immunity
Don’t produce antibodies
Directly attack foreign cells
Release proteins that have immune response
Antibody-mediate immunity
Produce antibodies
Types of t-cells
Helper
Cytotoxic
Suppressor
Memory
Stimulates other immune cells; secretes lymphocytes
Helper t-cells
Destroy abnormal cells by using toxic chemicals
Cytotoxic t-cells
Suppresses immune response after Ag has been destroyed
Suppressor t-cells
Reactivate upon exposure to Ag to form tn and tc cells
Memory t-cells
Where do we get natural acquired active immunity
During infections
Where do we get artificially acquired active immunity
Through vaccine
Where do we get naturally acquired passive immunity
From mother
