3/24- Lympathetic System (Exam 3) Flashcards

1
Q

A

Parallel circulatory system

System of vessels that run next to blood vessels

Carry lymph under low pressure

Q

What are the 4 functions of the lymphatic system?

A

1) returns excess interstitial fluid to venous circulation
2) thus, helps to maintain normal blood pressure
3) lipid transport
4) fights infections

Q

Explain function 1

A

Drain away extra interstitial fluid out of tissue because it builds up and dump into veins

Q

Explain function 2

A

Blood volume drops and person can go into shock

Returning interstitial fluid we maintain the blood volume because it gets emptied into a vein

Q

Explain function 3

A

Lipids enter lymphatic system because too big to enter blood

Fatty acids enter lacteal

Travel in lymph duct through system

Fatty acids get into blood from a larger vessel

Q

What is the lymphatic capillaries or terminal lymphatics?

A

Smallest vessels

Branch through the tissues

Originated from blind pockets

Microscopic (larger diameter)

Simple squamous epithelium

  • cells overlap each other
  • fluid goes through
  • fluid gets stuck that try to leave

Q

What are lymphocytes and the 3 kinds?

A

WBC living in lymphatic system

3 kinds

1) T cells or lymphocytes
2) B cells or lymphocytes

Q

What immune defenses are NK cells involved in?

A

Non specific immune defenses

22
Q

What are T cells?

A

Majority of lymphocytes (80%)

Primary players in cell mediated immunity

23
Q

What is cell mediated immunity?

A

One of your defense cells attack your cells

24
Q

What are the different kinds of T cells?

A

1) cytotoxic T cells
2) helper T cells
3) Suppressor T cells

25
Q

What are cytotoxic T cells?

A

Cells that attack other cells in mediated cell immunity

26
Q

What are helper T cells?

A

Stimulate other T and B cells Into action

Activating our immune response

27
Q

What are suppressor T cells?

A

Inhibit the activity of T and B cells

So your immune system doesn’t fight your own body

28
Q

What are B cells?

A

Transform into plasma cells

Involved in antibody mediated immunity

29
Q

What are plasma cells?

A

Antibody factory

Immunoglobulin

30
Q

What is antibody mediated immunity or humoral immunity or humoral response?

A

Antibodies attack anything in body fluid

Even dissolved chemicals

31
Q

What are NK cells?

A

Non specific defenses

Go after tumor cells

Immunological surveillance

Tumor specific antigen

32
Q

What is immunological surveillance?

A

Patrol through body and if they encounter foreign cell they attack

33
Q

What is tumor specific antigen?

A

Oddball chemicals that show up in the membrane of cells in your body when they become tumor cells

34
Q

What is lymphpoieses?

A

Formation of lymphocytes

35
Q

What are the 2 basic structures in the lymphatic system?

A

1) lymphatic tissue

2) lymphoid organs

36
Q

What are lymphatic tissue?

A

No definitive edge

Blend with surrounding tissue

Can’t tell where the begin or end

Include MALT

37
Q

What is Mucosa-Associated Lymphoid Tissue (MALT)?

A

Take form of Nodule in CT

Example is your tonsils

38
Q

What is a nodule?

A

Tons of WBC in CT

39
Q

What are the 3 kinds of tonsils?

A

1) pharyngeal tonsils or adenoids

2) palatine tonsils
- back of roof of mouth
- pair of them (right and left)

3) lingual tonsils
- back of tongue
- pair of them (right and left)

Loaded with WBC and activates specific defenses

41
Q

What is a hilus?

A

Depression in lymph node

42
Q

What are the afferent lymph ducts?

A

Bring lymph in

Ducts entering lymph node

43
Q

What is the efferent lymph duct?

A

Lymph duct leaving lymph node

Take lymph out

44
Q

What is lymphadenopathy or adenopathy?

A

Lymph node swells if a lot are needed to fight off infection

45
Q

What is the thymus?

A

2 parts:

1) cortex
2) medulla

In mediastinum

Pink and grainy

Bottom of neck to top of heart

Shrinks as you get older

T cells produced

46
Q

What is the cortex of the thymus?

A

Outer layer

Lymphocytes become T cells

47
Q

What is the medulla of the thymus?

A

Inner layer

T cells migrate here when they mature

Leave thymus

48
Q

What are the hormones the thymus produces?

A

Thymosins

49
Q

What is are the 3 functions of the spleen?

A

1) filter of blood to remove old RBC
2) store iron from hemoglobin
3) start specific immune responses

Adults contains largest collection of lymphatic tissue

50
Q

What is the tissue of the spleen called and the 2 kinds and explain them

A

Pulp

1) red pulp- iron is stored
2) white pulp- filters blood removing invaders and starts immune responses

51
Q

Where is the spleen located?

A

Left hand side of body

High up of abdominal cavity

52
Q

What is the artery and vein of the spleen called?

A

Splenic Arter- part of celiac trunk

Splenic Vein- part of hepatic portal system

80
Q

What is a lymph node?

A

Hilus

Afferent and efferent lymph ducts

Filter the lymph

1-25 (1 in)

Connected to lymph ducts
