|
|
|
adaptive immunity (what is another name for it?)
|
acquired immunity, means over time immune system is able to increasingly recognise specific antigen
|
|
|
antibiotis
|
chemical that kills/ injures bacteria
|
|
|
antibody
|
protein produced by B lymphocytes in response to the presence of an antigen (released in to the blood stream)
|
|
|
antigen
|
foreign substance, often a protein, that is not produced by the body. Its presents causes antibodies to be produced
|
|
|
antiviral drug
|
drug that kills or treats symtoms of a viral infection
|
|
|
autoimmune response
|
when immune system attacks its own tissue
|
|
|
B cells (whats another name for it)
|
B lymphocyte: special type of lymphocyte produces antibodies
|
|
|
immune response
|
body's response to a specific antigen
|
|
|
immunisation
|
artificial introduction of weakened antigens or pathogens to allow person the develop antibodies
|
|
|
infection
|
caused by the invasion and multiplication of pathogens
|
|
|
lymphocyte
|
a type of white blood cell that is produces in the bone marrow. they involve in immune response
|
|
|
lymphatic system
|
consists of lymph node and tubes that drain excess tissue fluid back into blood. Also protects body against invading pathogens (lymph glands store lymphacytes which fight disease)
|
|
|
pathogen
|
disease causing organism
|
|
|
phagocyte
|
type of white blood cell that engulfs particles such a bacteria and viruses
|
|
|
plasma cell
|
the B cell which produces antibodies
|
|

specific immunity
|
the bodys resistance to infection by pathogens that have gone past a non-specific defence
|
|
|
T cells (whats another name for it?)
|
T lymphocytes: kills antigen such as fungi and viruses
|
|
|
vaccine
|
substance that stimulates the immune system to produce antibodies to a particular antigen

strand of nucleic acid wrapped up in a protein coat
|
|
|
Summaries T cells (6)
|
T cells:
- form bone marrow - long lived - move to thymus during foetal development & after birth - mature in thymus - cell mediated immunity - effictive against viruses, fungi, cancer, bacteria |
|
|
Summaries B cells (4)
|
- Form in the bone marrow
- short lived - mature in the none marrow - antibody (humoral) mediated immunity - effective ahainst bacterial & viral infections |
