Flashcards in Immune System Deck (31):
1

Pathogen

Micro organisms that cause diseases in humans

2

Five types of pathogens

Fungi, bacteria, virus, prions, Protozoa

3

Six types of disease transmissions

Food borne, blood borne, airborne, vector, contact, sexual

4

Concerns over vaccinations

Causes disease, creates vaccine immune pathogens

5

What is the lymphatic system?

Cells, tissues, and organs that play a central role in the body's defenses against pathogens

6

What are functions of the lymphatic system?

Produce, maintain, distribute lymphocytes, maintain blood volume

7

Lymph

Fluid that circulates in the lymphoid system; colorless fluid filled with WBC's

8

Site of fluid exchange between the circulatory and lymphatic systems

Lymphatic capillaries

9

Where is the drainage of the lymph in the upper right side of the body?

Right jugular

10

Where is the drainage of the lymph in the left and lower sections of the body?

Left subclavian

11

How are nodules different than nodes?

They are smaller

12

What are three organs of the lymphatic system

Lymph nodes, thymus, and spleen

13

What organ system would be affected without the lymph system?

Circulatory and immune system

14

Why do we have an immune system?

To attack invaders from the inside and outside

15

What cells are the basis for all immune cells

Pluripotent stem cells

16

Five parts of the first line of defense

Barriers, traps, elimination, unfavorable pH, and lysozyme enzyme

17

Three leukocyte a in the second line of defense

Neutrophils, macrophages, and natural killer cells

18

How do neutrophils destroy pathogens?

Swallow pathogen, display parts on outside, release histamine

19

Macrophages

Swallow cell, break apart, release parts

20

Natural KC

Bind to cell, injects perforin which expands and causes apoptosis

21

How does the inflammatory response help defend against infection?

Slows bacterial growth, stimulates phagocytosis, speeds up repair of tissues

22

Two types of lymphocytes in 3rd line of defense

B cells and T cells

23

Where do B cells mature?

Bone marrow

24

Two types of B cells

Plasma cells and memory cells

25

B cells

Indirectly attack pathogens by producing antibodies that attach to antigens

26

Antibodies are analogous cellular...

Handcuffs

27

Three types of T cells

Helper T cells, killer T cells, memory T cells

28

Passive immunity

Recurve antibodies from someone else or a serum

29

Active immunity

Makes own antibodies

30

What is an auto immune disorder?

Immune system attacks its own molecules and cells

31

Epidemiology

The branch of medicinal science dealing with the transmission and control of disease
