Once a b-cell is activated, it enlarges and divides to produce
t-cells
memory b-cells
plasma cells
helper t-cells
Which cell eliminates infected cells?
helper t-cells
suppressor t-cells
lymphocytes
killer t-cells
What is the body’s first line of defense?
It is the inflammatory response of fluid and white
blood cells.
They're barriers to pathogens in the skin, breathing passages, the
mouth, and stomach.
It is the immune response.
Which of the following is an inflammatory response? choose all that apply:
Redness
Swelling
Fever
Heat
Chemicals secreted by WBCs that indicated infectious agents are present. This will be received by the hypothalamus and the body's temperature will increase.
fever
pyrogens
antigens
haptens
Which of the following are part of the bodies first line of defense?
skin
fever
inflammation
mucous membranes
Which of the following is involved with humoral immunity?
T Cells
Antibodies
Natural Killer Cells
Fever
Which of the following is an example of natural passive immunity?
getting the flu virus
vaccination
breast feeding
antibody serum injection
Which of the following is an example of artificial active immunity?
Breast feeding
Tamiflu
Maternal antibodies crossing the placenta
Vaccines
What is the function of antibodies within the immune system?
Antibodies kill off any antigen that enters the body.
Antibodies are only made when you are given a vaccination for specific antigens.
Antibodies bind to specific antigens to flag for destruction.
Antibodies are part of an external defense mechanism.
What happens after the second time you are exposed to a pathogen?
The body will not be able to fight off the pathogen quickly, because it knows how to get into the body easier.
The body's immune system will react the same was as it did during the first exposure.
The body can only be exposed to a pathogen a second time if you do not have a vaccine.
The body will know how to fight off the pathogen quickly, because memory cells have been created after the first encounter.
How do T cells differ from B cells?
T cells fight pathogens by killing pathogens directly, while B cells fight pathogens by making antibodies.
T cells only make memory cells, and B cells only make antigens
T cells fight pathogens by making antibodies, while B cells fight pathogens by killing pathogens directly.
T cells can only fight off pathogens the body has encountered once, and B cells can fight off any pathogen the body comes across.
what does HIV do to our immune system?
It makes our immune system more stronger
It attacks red blood cells
It attacks our brain to stop working
It attacks our Helper T cells and weakens our immune system to the point where our body cannot fight pathogens
What correctly describes antibodies?
They can attach to many different antigens
They are a part of the innate immune system
They are specific to their antigens
They are found on invasive bacteria
