Flashcards in lymphatic and immune system Deck (39):
1

functions of the lymphatic system?

-Remove waste
-Return excess fluid to blood stream
-Absorb fat from intestines
-Protect by filtering and destroying invaders

2

whats lymph?

Clear, transparent fluid with Antibodies and lymphocytes

3

where are Lymphatic vessels located?

throught the body

4

function of Lymphatic vessels?

allows Lymph to flows due to contractions of skeletal muscles then Returns to venous bloodstream

5

what Lymphatic capillaries?

thin walls that allow lymph in tissue to flow

6

what are lacteals?

Pick up/Absorb digested fats or lipids from capillaries in small intestines.

7

what are Lymph Nodes?

Masses of lymphatic tissue that filter lymph and remove impurities, traps microorganisms and produce lymphocytes.

8

whats the Flow of Lymph?

1.) Capillaries pick up lymph in tissues
2.) join to form larger lymphatic vessels
3.) Pass through lymph nodes
4.) Join to form larger lymph vessels

9

Right Lymphatic Duct functions?

-Receives all lymph from right upper body
-Empties into Right Subclavian Vein

10

location and function of Cisterna Chyli?

-At start of thoracic duct
-Stores purified lymph

11

Lymphatic Tissue examples?

tonsils, spleen, thymus

12

Lymphatic Tissue of tonsils locations?

-Palatine, Located on each side of soft palate
-Pharyngeal (Adenoids), Located in nasopharynx
-Lingual, Located on back of tongue

13

whats the spleen?

Largest organ of the lymphatic system

14

function of spleen?

-Produce leukocytes (WBCs)
-Produce antibodies
-Filter wastes
-Destroys/monitors erythrocytes
-Destroy thrombocytes (platelets)
-Stores/recycles RBC's

15

location of Thymus?

Located in center of chest, above heart

16

functions of the thymus?

-Produces antibodies/Helps fight infection
-Manufactures lymphocytes (WBCs)

17

Diseases of Lymphatic System?

Splenomegaly, Tonsilitis, Hodgkin’s Disease, Metastasis

18

whats Splenomegaly?

Enlargement of spleen

19

whats tonsilitis? treatment?

-inflammation or infection of tonsils
-Treated with antibiotics/throat gargles

20

whats Hodgkin’s Disease? treatment?

-Chronic malignant disease of lymph nodes
-Treated with chemotherapy/radiation

21

whats Metastasis?

Spread of cancer cells via the lymphatic system

22

whats the Immune System made up of?

specialized cells and organs

23

whats the immune systems function?

Provides protection against bacterial and viral infections, destroys cancer cells and foreign substances

24

what happens if immune system is weak?

the body’s ability to defend itself also weakens and
pathogens grow and flourish in the body.

25

whats an antigen?

A foreign substance
examples: Bacteria, virus, allergens

26

whats an antibody and its function?

-What body produces in response to antigen
-it protects against disease

27

whats immune response?

the body’s reaction to antigen exposure and the
body’s attempt to keep us free from disease.

28

whats biological immunity?

Protection from disease/Body’s ability to resist infection

29

Bone Marrow location and functions?

-located in the lymphatic system structures
-Provide a specific immune response to infectious diseases and Produce B and T cells

30

B cell location and function?

-located in the in bone marrow
-Produce antibodies against an antige

31

T Cells location and function?

-located in the thymus gland
- attack the antigens

32

whats Nonspecific Immunity?

Antigen that Invades the Body, mobilize the lymphatic system causing a Inflammatory Respons

33

whats specific Immunity?

were Body has previously encountered the antigen
Immune system remembers the antigen

34

Natural Passive immunity ?

From mother to child before birth/through breast milk

35

Natural Active/Acquired immunity?

Develop antibodies during an actual attack of infectious disease

36

Artificial/Acquired Passive immunity?

Acquire immunity after receiving antiserum/antitoxin that has antibodies (IgG)`

37

Artificial/Acquired Active immunity?

Acquire immunity artificially through vaccinations (immunizations)

38

phagocytosis?

cells that carry out processes, eating other cells

39

hydroelectric acid?

digestive chemicals in the body
