Q

crypts

A

histologically, tonsils do not contain a complete capsule, and the epithelial layer invaginates deeply into the interior of the tonsil to form tonsillar crypts

25
efferent lymphatic vessels
lead out of a lymph node
26
graft-versus-host disease
in bone marrow transplants, occurs when the transplanted cells mount an immune response against the recipient
27
histamine
vasoactive mediator in granules of mast cells and is the primary cause of allergies and anaphylactic shock
28
hypersensitivities
reacting to something that would not normally evoke a reaction
29
hypothyroidism
underactive thyroid gland
30
induration
a firm, raised reddened patch of skin
31
inflammation
basic innate immune response characterized by heat, redness, pain, and swelling
32
innate immune response
rapid but relatively nonspecific immune response
33
interferons
early induced proteins made in virally infected cells that cause nearby cells to make antiviral proteins
34
lupus
an autoimmune disease in which the body mounts an immune response against its own tissues
35
lymph
fluid contained within the lymphatic system
36
lymph node
one of the bean-shaped organs found associated with the lymphatic vessels
37
lymphatic capillaries
smallest of the lymphatic vessels and the origin of lymph flow
38
lymphocytes
white blood cells characterized by a large nucleus and small rim of cytoplasm
39
lymphoid nodules
unencapsulated patches of lymphoid tissue found throughout the body
40
macrophages
a type of leukocyte that can ingest and destroy other cells or pathogens
41
mast cell
cell found in the skin and the lining of body cells that contains cytoplasmic granules with vasoactive mediators such as histamine
42
memory T cells
long-lived immune cell reserved for future exposure to a pathogen
43
MHC
major Histocompatibility Complex molecules
44
monocyte
precursor to macrophages and dendritic cells seen in the blood
45
mucosal
mucous membranes line body cavities that open to the outside world, including the respiratory tract, gastrointestinal tract, urinary tract, and reproductive tracts
46
opsonization
an antibody or an antimicrobial protein binds to a pathogen, thereby marking it as a target for phagocytes
47
passive immunity
transfer of immunity to a pathogen to an individual that lacks immunity to this pathogen usually by the injection of antibodies
48
pathogens
disease causing agents
49
phagocytized
process by which certain cells are able to eat other cells
50
primary adaptive response
immune system's response to the first exposure to a pathogen
51
rheumatoid arthritis
an autoimmune disorder in which the body mounts an immune response against its own joint tissues
52
right lymphatic duct
drains lymph fluid from the upper right side of body into the right subclavian vein
53
S aureus
staphylococcus aureus is a bacterium that is commonly found in minor skin infections, as well as in the nose of some healthy people
54
severe combined immunodeficiency disease (scid)
genetic mutation that affects both t cell and b cell arms of the immune response
55
spleen
secondary lymphoid organ that filters pathogens from the blood (white pulp) and removes degenerating or damaged blood cells (red pulp)
56
superficial lymphatics
lymphatic vessels of the subcutaneous tissues of the skin
57
thoracic duct
large duct that drains lymph from the lower limbs, left thorax, left upper limb, and the left side of the head
58
thymus
primary lymphoid organ, where t lymphocytes proliferate and mature
59
tonsils
lymphoid nodules associated with the nasopharynx
60
vaccine
a killed or weakened pathogen or its components that, when administered to a healthy individual, leads to the development of immunological memory (a weakened primary immune response) without causing much in the way of symptoms
61
wheal and flare response
a soft, pale swelling at the site surrounded by a red zone
