Flashcards in Lymph and Immunity Deck (47):
1


What are pre-T cells in the thymus called?


thymocytes

2

Immunoglobulin that can leave blood and enter tissue fluids. It plays an important role in preventing diseases caused by antigens that may enter the body through mucosal surfaces.

IgA

2

What is the function of plasma cells?


To produce, store, and release antibodies

2

What is an interferon?


Protein produced by a cell after it has been infected by a virus

3

What does red pulp consist of?

Blood vessels, tissue macrophages, and blood storage spaces (sinuses)

4

General term for the formation of white blood cells

Leukopoiesis

5


What is the primary source of passive immunity in veterinary medicine?


Colostrum

5

What pushes lymph back towards the heart?


Body Movement

6

What is the function of memory cells?

They wait for a second infection of the same antigen that originally caused their formation.  The immune response is more rapid the second time the body is exposed to the antigen.

6

What is the IgE antibody associated with?

Allergic response

6

Which is the first antibody that is produced when an animal is exposed to an antigen?

IgM

6


Which antibody arrives after IgM but stays at the site longer?


IgG

7

5 types of immunoglobulins (Ig)

IgM, IgG, IgA, IgE, and IgD

9

The 2 types of specific immunity

cell-mediated immunnity and humoral immunity

10

Cell type involved in humoral immune response  

B cells that transform into plasma cells after antigen stimulation

11

which type of white blood cell is incapable of phagocytosis

Lymphocytes

12

what type of cells are memory cells

T cells

B cells

13

what lymphoid organ is full size at birth. then gets smaller with age

Thymus

14

Lymph fluid re-enters the bloodstream via what large lymph vessel near the heart?

Thoracic duct.

15

What organs are part of the lymphatic system?

Lymph nodes, spleen, thymus, tonsils, and gut associated lymph tissue(GALT)

16

what are the 4 primary functions of the lymphatic system?

Removal of excess tissue fluid, waste material transport, filtration of lymph, and protein transport,

16

What provides a rapid response to foreign invaders?

Nonspecific Immunity

17

What is Cell-Mediated Immunity?

The function of T cells that attach to antigenic sites on the surfaces of foreign cells.

18

What are Suppressor T Cells?

These cells inhibit helper T cell and cytotoxic T cells function by negative feedback. They prevent B cells from transforming into plasma cells.

19


What is special about cells in the white pulp of the spleen.

They can clone themselves during an immune response.

20


What does GALT satnd for?

Gut associated lymph tissue.

22

What are tonsils?

noduals of lymphoid tissue that are not covered with a capsule.

23

What type of white blood cell is this

Q image thumb

monocyte

25

What is active immunity

Activation of the immune system by administration of a vaccine that contains a modified antigen or exposure to the antigen.

26

What is passive immunity

administering antibodies that weren't produced by the animals own immune system.

28


Lymphocytes

B-Cells and T-Cells

29

What type of cell is this?

Q image thumb

Neutrophil

31


Agranulocytes

Monocytes, Lymphocytes

32


Granulocytes

Neutrophils, Basophils, Eosinophils

33

What is lymph filtered by?

Lymph Nodes

34

Which part of the spleen acts as reservoir for blood?

Red Pulp

35

T- Lymphocytes are produced in the __ and mature in the ___.

Bone Marrow and Thymus

36

What are the two types of immune response?

Specific and Nonspecific

38

 

what does chemotaxis do?

 

Uses chemicals to attract neutrophils to the site of an infection

40

What are lymphokines?

Chemical messengers secreted by T cells - also called cytokines

41

On the way to the thoracic duct, lymph vessels pass through at least one lymph node and pick up what?

Lymphocytes

42

What is the Lymph from the digestive tract called?

Chyle

43

Where is GALT located?

the lining of the intestine
