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.
Which of the following statements are TRUE about vaccinations?
Allow B cells to make antibodies for any type of antigen the body comes in contact with.
Triggers the body to make memory cells for specific pathogens.
They are substances prepared from killed or weakened pathogens.
Always allows the body to resist an infectious disease any time it comes into contact with it.
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 Killer T-Cells differ from Plasma 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.
The blue molecule in this image is a(n) _______.
Antibody
Antigen
Pathogen
Blood cell
The orange molecule in this image is a(n) _______.
Antibody
Antigen
Antibiotic
Blood cell
These cells hep to activate or program certain cells in Humoral AND Cell Mediated Response
helper T cell
mast cell
cytotoxic T cell
plasma cells
A key part of the humoral immune response is
the attack of cytotoxic T cells on infected host cells.
the production of antibodies by plasma cells.
perforation of infected host cells by perforin.
the attack of phagocytes on living pathogens.
Secondary immune responses upon a second exposure to a pathogen are due to the activation of
memory cells.
macrophages.
stem cells.
B cells.
If a person has already had chicken pox, why do they generally not get sick a second time?
Memory B and T cells activate the immune system before the virus has a chance to make you sick
Natural killer cells recognize the pathogen quicker
Your 1st line of defense does a better job
What cell marker is used by white blood cells to start a Cell Mediated Repsonse?
An antigen
An Antibody
A MHC
None of the above
