Flashcards in Chapter 21 Deck (47):
1

Fluid that surrounds tissue cells; comes from capillaries and hydrostatic pressure that moves into tissues

Interstitial/extracellular fluid

2

Interstitial fluid in lymph capillaries

lymph

3

What makes up lymph?

Water, dissolved solutes, hormones, small amount of proteins

4

Returns fluid back to blood circulation; smallest lymph vessels that are close-ended

lymph capillaries

5

Where are lymph capillaries located?

in and around blood capillaries

6

What do overlapping endothelial cells do for lymphatic capillaries?

lets fluid in not out

7

specialized lymph capillaries located in GI tract; responsible for absorption of lipid soluble substances

Lacteals

8

Steps for movement of lymph into lymphatic capillaries

Increase in hydrostatic pressure, pushes interstitial fluid in lymph capillaries, traps lymph so it won't escape

9

Larger structures that transport lymph

Lymphatic vessels

10

Where are lymphatic vessels located?

Superficial veins, deep arteries and veins

11

Do lymphatic vessels have low or high pressure?

low

12

What moves lymph through lymphatic vessels?

valves, skeletal muscle pump, respiratory pump, pulsatile movement of blood

13

Remove lymph from a specific region

Lymphatic trunk

14

Drain lymph from head and neck

Jugular trunk

15

Remove lymph from upper limbs, breast, superficial thoracic wall

Subclavian trunk

16

Remove lymph from deep thoracic structures

Bronchomediastinal trunk

17

Drain lymph from most abdominal structures

Intestinal trunk

18

Remove lymph from lower limbs, pelvic organs, abdominopelvic wall

Lumbar trunk

19

Located near the right clavicle; collect lymph from right side of body above diaphragm and dump it into the right subclavian vein

Right lymphatic duct

20

Larger extends from diaphragm to near the left clavicle; dumps lymph into left subclavian vein

Left lymphatic duct

21

Sac at the base of the thoracic duct; receive lymph from small intestine and lumbar trunks

Cisterna chyli

22

Involves in formation and maturation of lymphocytes

Primary lymphatic structures

23

What are some examples of primary lymphatic structures?

Red bone marrow, thymus

24

Serve house to lymphocytes and immune cells, site where immune response is initiated

Secondary lymphatic structures

25

What are some examples of secondary lymphatic structures?

lymph nodes, spleen, tonsils, MALT, lymphatic nodules

26

Production and maturation of lymphocytes in bone marrow

Lymphopoiesis

27

Produce antibodies; indirectly attacks pathogen

B-lymphocytes

28

Coordinate immune response, directly attacks pathogen

T-lymphocytes

29

B-lymphocytes maturation, formation of all formed elements

Red bone marrow

30

Where is red bone marrow located?

Within spongy bone

31

T-lymphocytes maturation and formation

Thymus

32

Where is the thymus located?

superior mediastinum (adults), anterior and superior mediastinum (kids)

33

Small round encapsulated structures that filter lymph and remove unwanted material

Lymph nodes

34

Where are lymph nodes located?

Intersections of lymph vessels

35

Lymph from head and neck

Cervical lymph nodes

36

Lymph from upper limbs, axillary, breast

Axillary lymph nodes

37

Lymph from lower limbs and pelvis

Inguinal lymph nodes

38

Where is the spleen located?

Left upper quadrant of abdomen, underneath the diaphragm

39

What is the function of the spleen?

Phagocytosis of bacteria, filter blood, blood reservoir

40

What type of formed element in blood does the spleen house?

Platelets

41

Non-encapsulated lymphatic tissue that trap and eliminate foreign material from entering digestive or respiratory system

Tonsils

42

Posterior wall of nasopharynx

Pharyngeal tonsils (adenoids)

43

Posterolateral region of oral cavity

Palatine tonsils

44

posterior 1/3 of tongue

Lingual tonsils

45

Clusters of lymphatic tissue to defend against foreign materials

MALT (mucosa associated lymphatic tissue)

46

Where is MALT located?

lining of GI tract, respiratory tract, urinary tract, reproductive tract

47

Collection of lymphatic tissues in small intestine

Peyer patches
