Week 7 Lymphatic Continued Flashcards
Specific or non-specific defense system protects against any threat
non-specific
Specific or non-specific defense system protects against a specific antigen
specific
What are the 7 non-specific body defenses
- physical Barries- skin
- Phagocytes -remove debris and pathogens like macrophages
- NK Cells- immunological surveillance
- Interferons- small proteins relseased by cell infecteced with virus
- complement system
- inflammatory response
- fever
Small proteins released by virus-infected cells
interferons
What system Destroy target cell membranes and Stimulate inflammation, attract phagocytes
complement system
What is innate immunity?
Genetically determined or Present at birth
What is active acquired immunity?
Following exposure to a pathogen either naturally or via a vaccine
What is passive acquired immunity?
immunity comes From transfer of antibodiesfrom outside source as in IGG/IGIV infusions or getting antibodies from breast milk as a baby
which cells remember an antigen?
memory T cells
what cells suppress other b or T cells so they don’t continue to overacticate?
suppressor T cells
cytotoxic T cells destroy target cell with what 3 things?
cytokines
lymphotoxin
perforin
what cells produce antibodies?
plasma cells
What immunoglobulin is associated with resistance to pathogen?
IgG
What immunoglobulin is associated with being the 1st antibody secreted?
IgM
What immunoglobulin is found in glandular secretions?
IgA
What immunoglobulin is associated with stimulating inflammation
IgE
What immunoglobulin is found on the surface on B cells
IgD
Antibodies produced by plasma cells after first exposure to antigen
primary response
Maximum antibody levels produced by subsequent exposure to the same antibody
secondary response
Immunization produces a (primary or secondary) response to a specific antigen
primary
what cell Slows growth, kills tumor cells
Tumor necrosis factors (TNF)
what cell slows the spread of viruses locally?
Interferons
do viruses replicate inside or outside of cells?
inside
do bacteria live inside or outside of cells?
usually outside
