1) Immunization happens by injecting
2) What are immune effector functions for?
3) What are immune regulation functions for?
4) The 2 surfaces through which pathogens enter?
1) dead, attenuated form of pathogen or its antigen
2) Pathogen clearance
3) To avoid unintentional damage to cell
4) skin and mucosa
The bodies natural defense systems include natural barriers, innate and adaptive immunity.
1) The 3 natural barriers are?
2) What type of immunity is specific?
3) Describe innate and adaptive immunity with two attributes.
4) Compare innate and adaptive immunity in regards to: i) response time,
whether they are ii) fixed or variable,
iii) specificities, and iv) whether they improve during response
1) skin, tears, mucus
2) adaptive
3) innate: anti microbial peptides that are pre formed and induced by inflammation.
adaptive: antibody production by B cells
effector T cells.
4) i) innate responds faster
ii) innate is fixed
iii) innate has less specifities
iv) constant during response
1) Describe the four hallmarks of inflammation: HRSP
2) Assume that your your skin gets cut and bacteria enters it. i) What does the bacteria do to the resident effector cells
ii) What happens after that?
1) heat, redness, swelling and pain
ii) Bacteria causes resident effector cells to release cytokine
ii) Vasodilation and increase in permeability of the nearby blood vessels causes inflammatory agents to move into the tissue
1) Clonal expansion of B and T cells occur where?
2) Which immune deficiency is worse and why? innate vs adaptive
1) B: bone marrow, T: thymus
2) innate deficiency because they occur before the adaptive one
Image: 1) Clonal expansion of B and T cells occur where? 2) Which immune deficiency is worse and why? innate vs adaptive
1) What do inflamed tissues recruit to protect themselves against pathogens?
2) Describe the function of these immune cells
i) monocyte
ii) macrophage
iii) megakaryocte
iv) mast cell
v) dendritic cell
vi) small lymphocyte
vii) plasma cell
viii) natural killer cell
ix) neutrophil
x) eosinophil
xi) basophil
3) Describe how these immune cells form in a flow chart. What is the process of the formation of these cells?
1) monocytes
2) i) monocyte is the precursor to macrophage
ii) macrophages do phagocytosis
iii) megakaryocytes form platelets
iv) mast cells release granules to expel parasites v) dendritic cells activate T cells
vi) small lymphocytes produce antibodies
vii) plasma cells are fully differentiated B cells
viii) NK cells kills the actual cells that were infected by a specific virus
ix) neutrophil: phagocytosis
x) eosinophil: kills antibody coated parasites
xi) basophil control immune response to parasite
3) hematopoiesis

What is the process of the formation of these cells?
1) The two most important characteristics of adaptive immunity are:
2) Major cell types of the adaptive immunity are B cells, CD4 T cells and CD8 T. What do these do?
1) memory and specificity
2) B cells produce plasma cells
CD8 kills macrophages while the 4 activate macrophage and B cells and are helpers
Innate immune responses are produced at ____ whereas adaptive responses are at _____
site of infection, secondary lymphoid tissue
