Flashcards in CH 6 The Lymphatic and Immune System Deck (40):
0

One of two types of specific immunity that exist in the body, it is primarily mediated by B cells; also called humoral immunity

Anitbody-Mediated ( humoral) Immunity

1

A Large collection of lymph nodes located in the axilla ( Armpit)

Axillary Nodes

2

One of two types of specific immunity that exist in the body, it is primarily mediated by T-Cells

Cell-Mediated Immunity

3

Large collection of lymph nodes located in the neck

Cervical Nodes

4

Tissue with no clear boundary that blends with surrounding tissue and contains lymphocytes and other cells

Diffuse Lymphatic tissue

5

A Large collection of lymph nodes located in the groin

Inguinal Nodes

6

One of three sets of lymphatic organs that comprise the tonsils, they are located on the posterior margin of the tissue and help protect the body from bacteria introduced into the mouth and nose

Lingual Tonsils

7

Round or bean-shaped structure interspersed along the course of the lymph vessels, which filter the lymph and serve as a source of lymphocytes

Lymph Nodes

8

Tissue that is denser than diffuse lympathic tissue, found in the loose connective tissue of the digestive, respirtyory, and urinary system

Lymph Nodules

9

Thin-walled vessels through which lymph circulates through the body, they travel close to the major arteries and veins

Lymph vessels

10

One of two great lymph vessels, it empties into the subclavian vein

Lymphatic Duct

11

A passive circulatory system that transports a plasma-like liquid called lymph, a thin fluid that bathes the tissues of the body

Lymphatic System

12

A type of white blood cell that helps fight infection that provide immunity

Lymphocytes

13

Cells that leave the bloodstream and enter diseased tissue after the neutrophils and are responsible for the later stage of fighting infectione, including the disposal of dead bacteria

Macrophages

14

The spreading of disease from one part of the body to another, especially with man forms of cancer

Metastasize

15

Immune response that is predictable each time the bod is exposed to particular challenge

Nonspecific Immunity

16

One of three sets lymphatic organs that comprise the tonsils. They are located in the back of the throat, on each side of the posterior opening of the oral cavity, and help protect the body form bacteria introduced into the mouth and nose

Palatine Tonsils

17

The process of ingesting and destroying foreign matter by certain types of leukocytes

Phagocytosis

18

One of three sets of lymphatic organs that comprise the tonsils, they are located near the internal opening of the nasal cavity and help protect the body from bacteria introduced into the mouth and nose. Also called adenoids

Pharyngeal Tonsils

19

The immune response to given substance that is faster and stronger after each subsequent exposure

Specific immunity

20

An organ of the lymphatic system that is located in the left upper quadrant of the abdomen and consists of two types of lymph tissue: (Red Pulp; (venous drainage) and White Pulp (arterial drainage). that are associated with drainage of the spleen

Spleen

21

A triangular- shaped gland located below the sternum in the superior mediastinum that produces lymphocytes ( Large in infants, shrinks at we get older.)

Thymus

22

A response of the immune system that results in the influx of cells and other chemicals to fight a foreign challenge.
the most common chemicals are histamin, kinins, complement,prostaglandines, leukotrienes, pyrogen, and interferon

Inflammatory Response

23

Prevents back flow through the vessels

Valves

24

Has to passe through at least one to return back the bloodstream

Lymph Node

25

Are the most important component of the immune system

Leukocytes

26

these are also called nodes

Glands

27

Comprised of 80% to 85% of total serum antibody and is responsible for numerous actions: ex Rh antigens that destroy the fetus

IgG

28

Common means of disease transmission form person to person

Air born, body substance , injection , and oral transmission

29

Infectious disease that is spread through droplets from coughing and sneezing ( prevalent in nursing homes, homeless shelters, hospitals, prisons, migrant farms, IV drug users.

Tuberculosis (TB)

30

Bacteria

UTI

31

Viruse

AIDS, Common Cold

32

Fungi

Athletes Foot, Valley fever

33

Protozoans

Malaria

34

Nematodes

Anal itch

35

prions

Mad cow, strep throat

36

Certain body sites are normally colonized by various bacteria. Help keep homeostasis. Located in the gastrointestinal tract

E Coli

37

Genetic or natural passive immunity results when antibodies produced by the mother cross the placenta barrier to provide protection against fetal infections

Natural Immunity

38

Develops in one's life time and is a reaction in the body occuring as a result of natural exposure to invaders or from a deliberate exposure to an antigen

Acquired Immunity

39

Frequent infections diseases in the prehospital setting

Pneumonia and hepatitis
