Flashcards in immune system Deck (14):
0

inherited

Sickle cell anemia, hemophilia

1

pathogens

Bacteria: bronchitis
Protist: malaria
Fungi: athletes foot

2

pollutants

Biological molds, dander, etc in the air causes asthma. Chemical causes brain damage, seizures, death

3

organ malfunction

heart attack, kidney failure

4

lifestyle choices

lung cancer caused by smoking, skin cancer STDS HIV AIDS (abstinence!!!!)

5

1st line defense

Skin membranes (blocks from entering body), sweat tears and saliva (contain chemicals tht kill bacteria), mucus (entraps pathogen), stomach acid (destroys many pathogens in food)

6

2nd line of defense

Inflammatory response (local reaction prick finger sends out histamines) macrophages (giant WBC phagocytes digest pathogens)

7

3rd line defense (immune system)

Antigen (causes immune response), lymphocytes (WBC recognize specific antigen) including B-cells (memorize antigen) T-cells (helper recognize, killer attack)

8

Active immunity

Get dead/weak form of disease/it's product to trigger immune response

9

Inborn immunity

Immunity present at birth

10

Passive immunity

Given antibodies from outside source (breast milk)

11

Allergy

Immune response to something harmless

12

HIV

Causes aids, kills dem WBC to weaken immune system

13

Organ transplant

Take immunosuppressants to decrease immune response so they don't reject new organ
