1. 1st & 2nd Line of Defense
Nonspecific
2. 3rd Line of Defense
Specific, results in long term immunity.
Ex. TCells, BCells, & Antibodies (Ab)
3. Antigens
Chemical substances, usually a nonself invader
4. Body recognizes______.
antigenic surface determinants.
5. Origin of Immune System
Fetus 2mnths after conception; stem cells develope in the bone marrow with variety of stem stem cells.
2 Types: Ex. Erythropoietic RBC's
Ex. Lymphopoietic Lymph node site
6. Dual System of________.
Immunity
7. CMI ( Cellular Mediated Immunity)
Involves Tcells(advcd. life span, more than half circulating), Lymphokines & Interleukins.
8. Lymphokines
Protein produced by lymphoblasts; relates to 2nd level, & increases efficiency of phagocytosis.
9. Interleukins
Produced by WBC's, influences activity of other WBC's.
10. CMI's are found in 4 Classes of TCells:
1. Helper TCells
2. Supressor TCells
3.Cytotoxic TCells (Killer TCells)
4. Delayedhypersensitivity (Memory TCells)
11. Helper TCells
Signal to produce more Tcells.
12. Supressor TCells
Reduce production of Tcells.
13. Cytotoxic Tcells (Killer TCells)
Destroy antigens
14. Delayed hypersensitivity (Memory TCells)
Destroy future,reappearing nonself foreign antigens, resulting in long term immunity.
15. _____ & ______ aid in BCell production & reduction.
Helper TCells & Supressor TCells
16. BCells remain in ______.
Lymphoid tissue, called plasma cells.
They go through many adaptations; end result is production of antibodies.
17. Humeral Immunity
Rises from our B cells
18. Antibody
Globulin groups of protein
19. Immunoglobulins "aka" ___.
Antibodies
20. Antibody Structure
