Immune System

Question 1

System of Defense

Answer 1

1. Skin
2. Mucus Membranes
3. Body Chemistry
4. Specific Immunity

Question 2

Non-Specific Defense

Answer 2

Skin, Mucus Membrane and Body Chemistry

Question 3

Specific Defense

Answer 3

Specific Immunity

Question 4

Skin

Answer 4

• Waterproof
• Fungi and some pathogens can directly penetrait skin
• Herpes virus, worts, can penetrait skin

Question 5

Mucus Membrane

Answer 5

• Layer of playable tissue that secretes mucus
• Protection covering mucus membranes
• Mucus makes them moist, good covering so that pathogens cant get by
• Mucus has antibodies and it is acidic

Question 6

Body Chemistry (External)

Answer 6

External

• Skin
• acidic
• oils -> fatty acid
• sweat -> salt, Lysozyme (enzyme that break down bacteria)
• eyes
• tears -> lysozymes
• saliva
• stomach acid (pH2)
• Urine -> lots of salt

Question 7

Body Chemistry (Internal)

Answer 7

Internal (Inflamatory Response)

a) Curiculating chemicals send out alarm- histamines
b) Blood vessels dialate; flush wound, ^ temp
c) White blood cells move in to engulf invaders
d) Blood needs to clot ->clot
e) If still invader; fever and pus

Question 8

Pus

Answer 8

dead bacteria, dead white blood cells, plasma

Question 9

Macrophages

Answer 9

Big eater

Question 10

Phagotypes

Answer 10

Eating cell

Question 11

When blood vessels dialate what happens?

Answer 11

• Flush wound

- Temp goes up

Question 12

RBC Jobs

Answer 12

Carry oxygen, no nucleus and only produced in the bone marrow

Question 13

WBC Jobs

Answer 13

Eat worn out blood cells, Yes nucleus, is produced in bone marrow and it can also divide

Question 14

Platelets Job

Answer 14

Clot blood

Question 15

Plasma

Answer 15

Liquid part is water 90%

Nutrients, protein, CO2, ions, enzymes, hormones 10%

Question 16

Internal Body Chemistry CONT.

Answer 16

2 interferons (only work against virus, non-specific)

Question 17

Interferon

Answer 17

is a protein to alert/prevent viral infections

Question 18

Cell Membranes

Answer 18

Allows things to pass through (protein sticking out of the membrane, which is what the WBC checks)

Question 19

Virus…

Answer 19

A virus takes its DNA into the hosts nucleus

Question 20

Specific Immunity

Answer 20

• Antigen
• Antibody
• Antibiotic

Question 21

Antigen

Answer 21

foreign protein

Question 22

Antibody

Answer 22

protein that inactivates antigens (specific for every bacteria and virus that you have been exposed to)

Question 23

Antibiotics

Answer 23

chemical produced by fungi, fights bacteria

Question 24

WBC Types

Answer 24

Leukocyte- white cell
Lymphocyte- WBC thta live in lymph system
Macrophage- big eater
Phagocyte- eating cell
Basophyll- makes histimine
B-Cell- made in bone marrow
T-Cell- Made in the thymus (they become more specialized)
T4-Cell- Boss/cordinater (least amount)
T8 Supressor- Shuts down immune response
NK Cell- Natural Killer (Chemical warfare)
B Memory- Retain info on how to make antibodies
B Plasma- Activity making antibodies

Question 25

Vaccination

Answer 25

Contains an antigen, infect someone with an antigen to make a B-Memory Cell

Question 26

Blood Types

Answer 26

A, B, AB, O (Study Charts)
