1

What are the two primary functions of the lymphatic system?

Transport tissue fluid (lymph) to blood vessels. 2. protect the body by removing foreign material (bacteria) from the lymphatic stream and serve as a site for lymphocyte “policing” of body fluids and lymphocyte multiplication

2

What does the lymphatic system consist of?

Lymphatic vessels, lymphatic tissues, lymph nodes, and lymphatic organs.

3

What are the regional lymph nodes?

Cervical lymph nodes, axillary lymph nodes, and inguinal lymph nodes

4

Drains from upper right extremity, head, and thorax

Right lymphatic duct

5

receives lymph from the rest of the body

Thoracic duct

6

enlarged terminus of the thoracic duct, receives lymph from digestive organs.

cisterna chyli

7

Where does the lymphatic system carry lymph toward?

The heart. It is a one way system

8

bean-shaped filters lymph is transported through, which cluster along the lymphatic vessels of the body

Lymph nodes

9

Where are lymph nodes typically embedded?

In connective tissue

10

What are the organs of the lymphatic system?

Tonsils, thymus, spleen, appendix, peyers patches

11

a functional system that recognizes something as foreign and acts to destroy or neutralize it

Adaptive immune response

12

Adaptive immune response is also known as

immune response

13

protects us from bacterial and viral infections, bacterial toxins, and cancerbacterial toxins, and cance

immune response

14

What are the most important characteristics of immune response?

Memory, specificity, and self tolerance

15

What are the primary lymphoid organs

Thymus and red bone marrow

16

What are secondary lymphoid organs ?

tonsils, spleen, peyers patches

17

Primary cells for immune response?

B & T cells

18

Which cells originate in red bone marrow?

B & T Cells

19

riggered when an antigen binds to the specific cell-surface receptors causing the cell to proliferate rapidly, forming clones which then become specialized (differentiate) some form memory cells, other regulatory cells

Clonal selection

20

when a cell is able to distinguish between self and non self

self- tolerance

21

involves the addition of receptors on the cell surface that recognize and bind to a specific antigen

immunocompetent

22

Balls of connective tissue with collections of macrophages and and lymphocytes. Filter toxins and attack disease

Lymph nodules

23

Main cells of the immune system

Lymphocytes

24

Role of lymphocytes

target specific foreign substances or antigens

25

Types of lymphocytes

B cells and T Cells

26

Antibody producing cells

B cells

27

Directly attack target cells

T cells

28

Types of T-cells

Tc cells, Ts- cells, Th-cells

29

help alert and stimulate B cells

TH cell

30

Ctoxic cell which forms an army

Tc cells
