What is herd immunity?
The number of disease-fighting white blood cells in a person
Large number of individuals in a community becomes immune to a disease
Immunity in a herd of cows
The number of people that opt out of getting vaccinations
Also known as an immunoglobulin (Ig), this is a large, Y-shaped protein produced by plasma cells that are used by the immune system to identify and neutralize pathogens such as bacteria and viruses.
B cells
T cells
Antibody
Antigen
cytotoxic T cell
helper T cell
memory T cell
suppressor T cell
What do memory B cells do?
Kills the virus
Eats the virus
Patrol the area and make the immune system work faster next time.
Makes antibodies
Neutralization is when
antibodies bind to an antigen and activate complement
antibodies bind to an antigen and enhance phagocytosis
antibodies bind to an antigen and stop the antigen from binding to host cells
antibodies bind to antigens and cause them to clump together
Opsonization is when
antibodies bind to an antigen and activate complement
antibodies bind to an antigen and enhance phagocytosis
antibodies bind to an antigen and stop the antigen from binding to host cells
antibodies bind to antigens and cause them to clump together
Agglutination is when
antibodies bind to an antigen and activate complement
antibodies bind to an antigen and enhance phagocytosis
antibodies bind to an antigen and stop the antigen from binding to host cells
antibodies bind to antigens and cause them to clump together
The secondary immune response refers to
the immunity from the adaptive immune system
the second time the immune system encounters an antigen
the second line of immune defense- the innate immune system
the second time a person gets sick from a disease
Which type of immune hypersensitivity reaction is mediated by T cells?
Type l (immediate hypersensitivity)
Type ll (Cytotoxic)
Type lll (Immune complex)
Type lV (Cell Mediated)
In the secondary immune response (select two)
antibodies are produced more quickly after exposure than they were produced during initial exposure
the innate immune system is not important
the amount of antibodies produced is greater than the initial exposure
T cells are not needed
cytotoxic T cell
helper T cell
memory T cell
suppressor T cell
This type of immunity can be called nonspecific and refers to the bodies defenses that are present since birth.
resistance
adaptive immunity
acquired immunity
innate immunity
The process where leukocytes engulf and digest bacteria
leukocytosis
pathogenesis
hydrostatic pressure
phagocytosis
Which of the following are examples of innate (non-specific) immunity?
Skin forms a physical barrier to pathogens
T cells regognize specific antigens and cause cell lysis
Macrophages engulf bacterial cells at the site of infection
The body produces large numbers of memory cells with specific antibodies
What are the benefits of vasodilation in the inflammatory response?
Increases the vascular permeability so phagocytes can be recruited to the site of infection
Decreases vascular permeability so that phagocytes can stay within the bloodstream
Increases blood flow to allows better oxygenation
Increases blood flow to increased hydrostatic pressure and fluid leakage which dilutes toxic agents
Which of the following are outcomes of activation of the complement system? (select all that apply)
Activation of T cells
More inflammation
Restriction of phagocytosis
Lysis of a target cell
bring more phagocytes to the area
Lysozymes found in your tears, saliva, and blood are most effective against
Viruses
Bacteria
Fungi
Protozoans
Natural Killer Cells
Block adherence to host cells
destory virus-infected cell and tumor cells
phagocytose virus-infected cells
Block the complement cascase
The First Line of Immune Defenses describes
inflammation
phagocytosis
B cells
physical and chemical barriers
