23
Q
structure of the lymphatic and immune systems
A
-lymph nodes
-lymph vessels and fluid
-lymphatic organs
-network of vessels that collects and purifies excess tissue fluid throughout the body
24
Q
lymphatic organs
A
-tonsils
-thymus
-spleen
25
function of the lymphatic and immune system
-drain excess interstitial fluid from tissues and return it to the circulating blood
-absorb and transport digested fats to venous circulation
-produce lymphocytes and other immune cells that protect the body from injury and disease such as bacteria, viruses, and cancerous cells
26
lymph nodes
-small masses of lymph tissues
-also called lymph gland
-tend to occur in clusters or chains
27
location of major lymph node groups
-cervical (neck)
-axillary (armpit)
-inguinal (groin)
28
function of the lymph nodes
-lymph is filtered through these nodes as it passes through lymph vessels
-when bacteria accumulate in lymph nodes they become swollen and tender (bacterial infection)
29
spleen
-similar in structure and function to the lymph node but much larger in size
-filters lymph
-manufactures lymphocytes and monocytes
-destroys old erythrocytes
-stores new erythrocytes for release into the blood stream as needed
-not essential to life
30
thymus
secretes the hormone thymosin
31
thymosin
-secreted by the thymus
-stimulates red bone marrow to produce T lymphocytes (T cells)
32
T cells
-produced in the bone marrow
-provide a defense against disease
-attack and destroy foreign or abnormal cells
33
tonsils
-filter lymph
-destroy bacteria entering the mouth and throat
34
purpose of the lymphatic system
transport excess fluid from interstitial spaces in tissues and returns it to the blood and defends the body against foreign invaders and harmful substances
35
purpose of leukocytes
-defend the body against foreign invaders and harmful agents
36
tonsill/o
tonsil
37
cervic/o
neck
38
thym/o
thymus
39
splen/o
spleen
40
lymph/angi/o
lymph vessel
41
immun/o
immune; immunity; safe
42

43
aden/o
gland
44
lymph/o
lymph
45
phag/o
swallowing, eating
46
-oma
tumor
47
-phylaxis
protection
48
-poiesis
formation, production
49
thym/oma
tumor of the thymus gland
50
phag/o/cyte
cell that swallows or eats (ingests)
51
lymph/o/poiesis
formation or production of lymph
52
lymphangi/oma
tumor of a lymph vessel
53
agglutin/ation
process of clumping, gluing
54
immun/o/logy
study of immunity
55
splen/o/megaly
enlargement of the spleen
56
lymph/oma
tumor (composed of) lymph
57
lymphaden/itis or lymph/aden/itis
inflammation of a lymph gland (node)
58
lymphaden/o/pathy or lymph/adeno/pathy
disease of lymph glands
59
immun/o/logist
specialist in the study of immunity
60
thym/oma
tumor of the thymus gland
61
leukemia
malignancy of the blood-forming tissues of the bone marrow
62
hepat/o/meglay
enlargement of the liver
63
lymphedema
abnormal accumulation of lymph, usually in the extremities
64
mastec/tomy
removal of the breast
65
eryth/ema
swollen, red area of the skin that feels and tender
66
systemic lupus erythematosus (SLE)
-chronic inflammatory autoimmune disease
-unusual antibodies in the blood that target tissues of the body
-inflames and damages connective tissue anywhere in the body
67
corticosteroids
drugs that reduce inflammation
68
immunosuppressives
drugs to suppress the immune system
69

-lymphatic malignancy
-composed of multiple red or purple macules, papules, or nodules on skin and mucous membranes
-closely associated with HIV infection
70
hodgkin diesease
malignant disease characterized by painless, progressive enlargement of lymphoid tissue, splenomegaly, and the presence of unique Reed-Sternberg cells in the lymph nodes
71
lymphadenitis
inflammation and enlargement of the lymph nodes, usually a result of infection
72
mononucleosis
acute infection caused by Epstein-Barr virus characterized by a sore throat, fever, fatigue, and enlarged lymph nodes
73
