19
Q
antibiotics
A
medication capable of inhibiting the growth of or killing pathogenic bacteria
20
Q
antifungal
A
an agent that destroys or inhibits the growth of fungi
21
Q
antigen
A
any substanec that the body regards as being foreign
22
Q
antigen-antibody reaction
A
binding antigens to antibodies; this reaction labels a potentially dangerous antigen so it can be recognized and destroyed by other cells of the immune system
23
Q
autoimmune disorder
A
any of a large group of diseases characterized by a condition in which the immune system produces antibodies against its own tissues, mistaking healthy cells, tissues, or organs for antigens
24
Q
bacilli
A
rod-shaped, spore-forming bacteria
25
bacteria
A group of one-celled microscopic organisms, some of which are pathogenic
26
benign
something that is not life-threatening
27
candidiasis
a yeast infection
28
carcinoma
a malignant tumor that occurs in epithelial tissue
29
carcinoma in situ
a malignant tumor in its original position that has not yet disturbed or invaded the surrounding tissues
30
complement system
a group of proteins that normally circulate in the blood in an active form; when needed, these cells complement the ability of antibodies to ward off pathogens by combining with them to dissolve and remove pathogenic bacteria and other foreign cells
31
COVID-19
a highly contagious viral infection caused by the SARS-CoV-2 virus
32
cytokines
a group of proteins such as interferons and interleukins released primarily by the T cells; these cells act as intracellular signals to begin the immune response
33
cytomegalovirus
a type of herpesvirus found in most body fluids
34
cytotoxic drug
medication that kills or damages cells
35
ductal carcinoma in situ
breast cancer at its earliest stage before the abnormal cells have broken through the wall of the milk duct
36
hemolytic
destroying worn-out erythrocytes and releasing their hemoglobin for reuse
37
herpes zoster
an acute viral infection characterized by painful skin eruptions that follow the under lying route of an inflamed nerve
38
Hodgkin's lymphoma
a cancer of the immune system distinguished by the presence of large, cancerous lymphocytes known as Reed-Sternberg cells
39
human immunodeficiency virus
a bloodborne infection in which the virus damages or kills the T cells of the immune system, causing it to progressively fail, thus leaving the body at risk of developing many life threatening opporunistic infections
40
immunoglobulins
antibodies that bind with specific antigens in the antigen-antibody response
41
immunosuppressant
a substance that prevents or reduces the body's normal immune response
42
immunotherapy
a disease treatment that involves either stimulating or repressing the immune system
43
infiltrating ductal carcinoma
breast cancer that starts in the milk duct and invades the fatty breast tissue outside the duct
44
interferons
produced on response to the presence of antigens, particularly viruses or tumor cells; interferons activate the immune system, fight viruses by slowing or stopping their multiplication, and signal other cells to increase their defenses
45
lyphadenopathy
any disease process affecting a lymph node or nodes
46
lymphangioma
a benign tumor formed by an abnormal collection of lymphatic vessels due to a congenital malformation of the lymphatic system
47
lymphedema
swelling of the tissues due to an abnormal accumulation of lymph fluid within the tissues
48
lymphocytes
also known as lymphoid cells; leukocytes that are formed in bone marrow as stem cells; work together with the body's organs to defend the body against antigens
49
lymphoma
a general term applied to malignancies affecting lymphoid tissues
50
lymphoscintigraphy
a diagnostic test that is performed to detect damage or malformation s of the lymphatic vessels
51
macrophage
a type of leukocyte that surrounds and kills invading cells; macrophages also remove dead cells and stimulate the action of other immune cells
52
malaria
a disease caused by a parasite that lives in certain mosquitoes and is transferred to humans by the bite of an infected mosquito
53
malignant
becoming progressively worse and life-threatening
54
mammography
an x-ray examination of the breasts to detect the presence of tumors or precancerous cells
55
metastasis
describes the process by which cancer is spread to a new site, and the term is also used to describe the tumor itself.
56
metastasize
to spread from one place to another, as in cancer
57
myoma
benign tumor of the muscle tissue
58
myosarcoma
malignant tumor derived from muscle tissue
59
non-Hodgkin's lymphoma
the term used to describe all lymphomas other than Hodgkin's lymphoma
60
opportunistic infection
infection caused by a pathogen that does not normally produce an illness in healthy humans
61
osteosarcoma
a hard-tissue sarcoma that usually involves the upper shaft of long bones, pelvis, or knee
62
parasite
a plant or animal that lives on or within another living organism at the expense of that organism
63
rabies
an acute viral infection transmitted to human by the bite or saliva of an infected animal
64
rickettsia
a small bacterium that lives in live, fleas, ticks, and mites
65
rubella
viral infection characterized by a low-grade fever, swollen glands, inflamed eyes, and a fine, pink rash
66
sarcoma
malignant tumor that arises from connective tissues, including hard and, more commonly, soft tissues
67
spirochetes
long, slender, spiral-shaped bacteria that have flexible walls and aer capable of movement
68
splenomegaly
an abnormal lenlargment of the spleen
69
staphylococci
a group of about 30 species of bacteria that form irregular groups or clusters resembling grapes
70
steptococci
bacterio that form a chain
71
systemic reaction
also described as anaphylaxis or anaphylactic shock, is a severe response to an allergen; the symptoms of this response develop quickly, and without prompt medical aid, the patient can die within a few minutes
72
teletherapy
precisely targeted radiation therapy administered at a distance from the body
73
toxoplasmosis
a disease caused by a a parasite most commonly transmitted from pets to humans by contat with contaminated feces
74
varicella
a highly contagious infection caused by the herpesvirus Varicella zoster; also known as chickenpoz
