Q

what is the make up of the plasma that lymph is derived from

Q

how do lymphatic capillaries differ from blood capillaries

A
  • larger diameter
  • thinner walls
  • flat and irregular
  • have anchoring filaments that keep the passage open
  • overlapping endothelial cells

Q

formation of lymph

A
  • interstitual fluid enters capillaries
  • overlapping cells function as one way valves
  • moves through fenestrations
  • Large things such as viruses and debris follow

Q

route of the thoracic duct

A
  • cisterna chyli

23
Q

special thing about the thoracic ducts

A

unevenly drains fluid from the body:

  • thoracic does the majority
  • thoracic is much larger and drains the entire inferior half of the body
24
Q

movement of lymph– valves

A

occurs in bulges

prevent backflow

25
Q

how is lymph moved

A

with valves– pressure of lymph is less than veins– moved through skeletal muscles and breathing

26
Q

when drainage of lymph does not occur

A

lymphedema

27
Q

primary cells of the lymphoid system. allow for specific immunity or adaptive immunity

A

lymphocytes

28
Q

multi-faced immune response to the detection of specific foreign antigens

A

specific immunity

29
Q

type of lymphocyte derived directly from bone marrow

  • involves NON-SPECIFIC IMMUNITY
  • detects chemical signals other than specific antigens and induce apoptosis
A

NK cells (natural killer cells)

30
Q

type of lymphocyte that originates and developes in the bone marrow

  • stimulated by an antigen to produce antibodies
  • can survive for years as a memory cell and become active once exposed to a similar antigen
A

B cell

31
Q

type of lymphocyte that originates in the bone marrow but developes in the thymus

  • attack cells with antigens indicating viral infection or detrimental mutations
  • induce apoptosis
  • have memory cells similar to B cells
A

T cells

32
Q

reticular connective tissue dominated by lymphocytes. NOT organs, made up of mucosa associate lymphoid tissue. digestive lymph nodules

A

lymphoid nodules

33
Q

MALT tissues

A

tonsils, aggregated lymphoid nodules, and appendix

34
Q

part of MALT that is positioned around the pharynx. removes pathogens that enter via the air or food. three types: pharyngeal, palatine, lingual

A

tonsils

35
Q

MALT tonsils that is located in the nasopharynx– one nodule

A

pharyngeal tonsil

36
Q

MALT tonsil located in the soft palate– two nodules

A

palatine tonsil

37
Q

MALT tonsil located at the base of the tongue– two nodules

A

lingual tonsil

38
Q

part of MALT that lines the mucosa of the small intestines

A

aggregated lymphoid nodules

39
Q

part of MALT that bind tubes at the beginning of the large intestines– very prone to infections

A

appendix

40
Q

surrounded by a fibrous, connective tissue capsule within the lymphatic system– involve lymph nodes, thymus, spleen

A

lymphatic organ

41
Q

bean shaped lymphatic organ that is between several afferent and one efferent vessel. has a hilus

A

lymph nodes

42
Q

found within lymph modes. indented region where BVs nerves and efferent lymph vessels connect

A

hilus

43
Q

part of lymph nodes– capusle that has trabeculae that subdivide it. has two regions: inner and outer cortex

A

cortex

44
Q

regions of the cortex

A

inner and outer cortex

45
Q

part of the cortex that consists of aggregated B cells

A

outer cortex

46
Q

part of the cortex that allow T cells to enter the blood

A

inner cortex

47
Q

part of the cortex of lymph nodes that have B cells leave through the efferent vessel

A

medulla

48
Q

found on the left side of the stomach. largest lymphatic organ. contains white and red pulp.

A

spleen

49
Q

found in the spleen. resembles lymph nodes

A

white pulp

50
Q

found in the spleen. contains large amounts of RBCs. has sinuses, macrophages, T and B cells

A

red pulp

51
Q

function of the spleen

A 
remove old RBC 
store and recycle iron
intiate immune response
blood resivour
RBC production in fetus
52
Q

in mediastinum.

  • first lymph organ to develope– grows until puberty and shrinks with age; replaced with fibrous and adipose tissue
  • 2 lobes: cortex and medulla
A

thymus

53
Q

part of the thymus– mostly made up of T cells

A

cortex of thymus

54
Q

part of the thymus– mostly reticular epithelial cells

A

medulla of thymus

55
Q

cortex produces these cells. mature and migrate into medulla. enter blood vessels and go into circulation

A

T cells of thymus

56
Q

produce thymosin. promote T cells differentiation

A

reticular cells of the thymus
