Anatomy Immune System Mimic Test
Terms in this set (32)
Explain what happens in the graph and why there is a difference between first and second exposure
antibodies being produced 0-7 days
What is the purpose of the MHC (major histocompatibility complex)?
distinguish self from non-self and identify cancer cells
Which cells will respond whether you have a viral infection or a bacterial infection?
helper T cells
What happens to people who receive flu vaccinations?
They develop an immunity to flu virus
transfer of antibodies from one individual to another
developing antibodies in response ti an antigen
Describe how HIV affects the body
HIV affects the body's ability to produce T cells
What are antigens
Foreign molecules that trigger the generation of antibodies
What cell types are responsible for initiating a secondary immune response (second exposure)?
What is made in the bone marrow?
B cells and T cells, these are then told what to do in the thymus
What is the purpose of the thymus?
Erythrocytes and neutrophils
What is Clonal selection?
Reproduction of identical cells to fight a specific pathogen
Define cytotoxic T cells
found in the CMI (cell mediated immune response)
Define natural killer cells
these cells puncture holes in bacteria but are not specific to infected cells
Define helper t cells
these cells secrete interleukin 2 to activate B cells and killer T cells
antigen presenting cells, large phagocytes
Define B cells
These turn into plasma cells
Which cells and which signaling molecules are responsible for initiating inflammatory response?
mast cells, histamines
A person exposed to a new cold virus would not feel better for one to two weeks because...
antigen receptors are not the same as for a flu virus which she has previously been exposed to
List the events that occur when a mammalian immune system first encounters a pathogen.
1) antigenic determinants from pathogen bind to antigen receptors on lymphocytes
2) lymphocytes specific to antigenic determinants from pathogen become numerous
3) lymphocytes secrete antibodies
4) pathogen is destroyed
5) only memory cells remain
Cell mediated immune response
control intracellular pathogen
Humoral immune response
control of freely circulating pathogens, use of antibodies
How does HIV damage your immune system?
destroys T cells CD4
What is AIDS?
acquired immune deficiency syndrome, takes away T cells, destroys immune system, look weak/thin, originated in chimps
Name of your autoimmune disease
type 1 diabetes
Symptoms of type 1 diabetes
low blood sugar, feel faint, can cause different diseases
Treatment options for type 1 diabetes
-blood sugar monitoring
Antibodies fight against disease through: neutralization
antibodies bind to pathogen to prevent them from entering or damaging cells
Antibodies fight against disease through: opsonization
antibodies coat the pathogen, stimulating the removal of pathogens by macrophages and other cells
Antibodies fight against disease through: complement activation
they trigger destruction of pathogens by stimulating other immune responses such as complement pathway
Antibodies fight against disease through: enhances what
enhanced natural killer cell activity
Antibodies fight against disease through: agglutination
process occurs if antigen is mixed with antibody
