Flashcards in Ch 23 Lec 1 - Lymphatic System Deck (93):
0

this is a network of vessels that aid in circulation of body fluids and is closely associated with the cardiovascular system

lymphatic system

1

lymphatic system produces, maintains, and distributes blank

lymphocytes

2

lymphatic system maintains normal blank and blank fluid volume

blood, interstitial

3

lymphatic system is an alternate route for the transport of blank

materials

4

transport fluid of lymphatic vessels

lymph

5

four sizes of lymphatic vessels

small lymphatic capillaries, medium lymphatic vessels, large lymphatic trunks, lymphatic ducts

6

lymphatic blank are the end of the line for lymphatic system

ducts

7

lymphatic vessels are absent in blank and blank

cns, avascular tissue

8

lymph is a fluid blank

connective tissue

9

lymph only occurs in the blank vessels

lymphatic

10

lymph is derived from these three things

interstitial fluid, lymphocytes, macrophages

11

lymph originates from blank

plasma

12

water and dissolved materials leak out of capillaries due to blank and blank

diffusion, filtration

13

blank liters per day enters interstitial spaces

27

14

interstitial fluid lacks blank and has low blank

proteins, oxygen

15

interstitial fluid moves into the lymphatic capillaries and is now known as blank

lymph

16

blank percent of interstitial fluid is absorbed

90

17

blank from tissues will go into lymph

residue

18

lymphatic capillaries are blank ended tubes

closed

19

lymphatic capillaries are in blank

interstitial spaces

20

lymphatic capillaries have a blank diameter, blank walls, flat and blank than blood vessels

larger, thinner, irregular

21

lymphatic vessels are blank and permeable

fenestrated

22

these are formed by the merging of lymph capillaries and are similar to veins and merge to form trunks, and travel with arteries of same size

medium lymphatic vessels

23

four parts of medium lymphatic vessels

interna, media, adventitia, valves

24

these are named for the region they drain like lumbar, intestinal, broncomediastinal, subclavian, jugular

lymphatic trunks

25

lymphatic trunks drain into blank

ducts

26

there are blank lymphatic ducts

two

27

two lymphatic ducts

thoracic, right lymphatic

28

lymphatic ducts deliver lymph to blank circulation at blank

venous, subclavians

29

at lymphatic ducts, lymph is reintroduced to blank

bloodstream

30

lymph becomes a part of blank and is circulated after lymphatic ducts

plasma

31

lymphatic duct that drains lower body, left arm, head and neck

thoracic

32

thoracic duct route arises from blank

cisterna chyli

33

thoracic duct goes through the blank and ascends in front of the blank column

diaphragm, vertebral

34

thoracic duct empties into blank

left subclavian vein

35

lymphatic duct that drains right side of head and neck and right arm

right lymphatic duct

36

lymphatic ducts unevenly blank fluid from body

drain

37

this lymphatic duct does the majority of draining

thoracic

38

thoracic duct is much longer and drains the entire blank half of the body

inferior

39

blank lymphatic duct drains into blank vein

right, subclavian

40

blank occur at bulges in lymphatic vessels

valves

41

valves prevent blank

backflow

42

pressure is lower in blank than in veins

lymphatics

43

lymph is moved using similar methods to blank

veins

44

if drainage does not occur of lymph it is called blank

lymphedema

45

primary cells of the lymphoid system and have an immune response to foreign antigens

lymphocytes

46

lymphocytes originate in the blank

bloodstream

47

lymphocytes move to blank and go into blank

peripheral tissues, lymph

48

lymphocytes return to the blank after going into lymph

bloodstream

49

blank cells mature in the thymus

t

50

these lymphocytes originate and develop in the bone marrow

b cells

51

lymphocytes are stimulated by an blank to produce blank

antigen, antibodies

52

lymphocytes can become activated upon exposure to the same blank at a later date

antigen

53

lymphocytes that originate in the bone marrow but develop in the thymus

t cells

54

T cells may attack blank cells or those infected by a blank

foreign, virus

55

T cells may stay on reserve only to become active if the blank reappears

pathogen

56

lymphocytes that are also derived directly from bone marrow and directly attack foreign cells

natural killer

57

reticular connective tissue is dominated by blank

lymphocytes

58

these are not organs but include mucosa associated lymphoid tissue (MALT)

lymphoid nodules

59

MALT has blank lymph nodules

digestive

60

lymph nodes are not the same as blank

nodules

61

MALT that is positioned around the pharynx and remove pahtogens that enter via air or food

tonsils

62

three types of tonsils

pharyngeal, palatine, lingual

63

tonsil with one nodule in nasopharynx like adenoids

pharyngeal

64

tonsil with two nodules on the soft palate

palatine

65

tonsils with two nodules at the base of the tongue

lingual

66

MALT that line mucosa of the small intestine

aggregated lymphoid nodules

67

MALT that is a blind tube at the beginning of small intestine and is an area that is prone to infection

appendix

68

appendix infected is called blank and allows the intestinal blank to enter underlying tissue

appendicitis, flora

69

these are surrounded by a fibrous connective tissue capsule and include lymph nodes, thymus, spleen

lymph organs

70

lymph organs that are bean shaped and lie between several blank and one blank vessel

lymph nodes, afferent, efferent

71

indented region where blood vessels, nerves, and efferent lymph vessels connect in lymph nodes

hilum

72

lymph nodes have a blank which has a capsule which has blank that subdivide it

cortex, trabeculae

73

two regions of lymph node cortex

outer, inner

74

region of lymph node cortex that consists of aggregated B cells

outer

75

region of cortex of lymph node that has T cells that enter blood here

inner

76

lymph node part where B cells leave

medulla

77

three locations of lymph nodes

cervical, axillary, inguinal, pelvic, abdominal, thoracic

78

lymph organ on left side of stomach and is the largest lymphatic organ

spleen

79

spleen part that resembles a lymph node

white pulp

80

spleen part that has large amounts of red blood cells and sinuses, macrophages, and t/b cells

red pulp

81

spleen removes old blank and stores blank

red blood cell, iron

82

spleen initiates blank and is a blank reservoir

immune response, reservoir

83

spleen does red blood cell production in blank

fetus

84

lymphoid organ in the mediastinum and is the first lymph organ to develop

thymus

85

thymus grows until blank and shrinks with blank

puberty, age

86

two lobes of thymus

cortex, medulla

87

lobe of thymus with mostly immature T cells

cortex

88

thymus cortex produces mature blank

t cells

89
