25
Q

molecules on the outside of cells or secreted by cells that are recognized by antibodies

A

antigen

26
Q

type of leukocyte; include B and T cells

A

lymphocytes

27
Q

y-shaped molecule that contains two antigen-binding sites

A

antibody

28
Q

surveillance system that screens the body for foreign molecules; system has no pump, moves due to skeletal muscles and one way valves

A

lymphatic system

29
Q

lymphatic organs that trap microbes

A

tonsils

30
Q

ie. injection of antibodies to a particular pathogen; enables immediate action of injected antibodies (such as antitoxins); body may need injection of the same antibodies if re-exposed to same pathogen

A

artificially acquired passive immunotherapy

31
Q

ie. antibodies made when you get chickenpox; can make and secrete those antibodies years later if re-exposed

A

naturally acquired active immunity

32
Q

function of some antibodies; induces a reaction that directly kills microbes

A

oxidation

33
Q

function of some antibodies; tags microbes to increase the chances and speed of microbe phagocytosis

A

opsonization

34
Q

lymphocytes that mature in the thymus; 70-85% of all lymphocytes in then blood

A

T cells

35
Q

attribute of adaptive immunity; allows the immune system to respond faster and more effectively during the second exposure to a particular pathogen

A

memory

36
Q

attribute of adaptive immunity; prevents the immune system from attacking the body itself

A

self-tolerant

37
Q

enable quick response by the body but no memory B and T cells are made so there is no protection against future infections

A

passive immune response

38
Q

signals used that regulate and coordinate immune system responses; signals that enhance immunological synapses

A

cytokines

39
Q

function of some antibodies; also triggers inflammation

A

activate complement

40
Q

type of antigens such as toxins or parts of the outside of microbes

neutralization

42
Q

cells of the adaptive immunity can produce these identical cells

A

clones

43
Q

lymphatic organ that filters blood and removes microbes and damaged RBCs

A

spleen

44
Q

ie. lymph nodes, spleen, tonsils, MALT

A

MALT

50
Q

organ located above the heart; where T cells mature

A

thymus

51
Q

form a one way system to collect and return fluid that escapes the circulatory system; also, system carries toxins and pathogens to areas where lymphocytes are concentrated

A

lymphatic vessels

A

plasma cells

54
Q

attribute of adaptive immunity; allows the immune system to have a different response depending on the antigen encountered

A

specificity

55
Q

attribute of adaptive immunity; results in the activation of the immune system when a specific antigen in encountered

A

inducibility

56
