1. Immune System
EQ: How do the components of the immune system work together to keep us free from disease?
Break up into two days- part of the immune (day 1) control the spread- vaccines (day 2)

2. why are people not vaccinating their children
Watch the following video and answer the questions on the back of your worksheet:
how does a vaccine work
why are people not vaccinating their children
why is it best to vaccinate at a younger age
would you vaccinate your children

3. Germ Theory
proposes that: small particles, called pathogens or pathogen agents, cause disease
Previously thought it was evil spirts
examples:
Viruses
Bacteria
Parasites
Fungi

4. Pathogens are spread by:
Direct Contact
Examples: kissing, shaking hands
Indirect Contact
Examples: touching a door handle or inhaling a pathogen

5. fights infection and prevents illness in the body
The Immune System:
fights infection and prevents illness in the body

6. Parts of the Immune System
skin: physically blocks pathogens from entering the body, first line of defense
Mucous membrane: in nose and throat; traps particles before they enter
Circulatory system: transports cells of the immune system

7. Part of the Immune System
Phagocyte: white blood cell that engulf (eats) and destroys pathogens aka macrophage
T cell: destroys infected body cells
Inside the cell
B cell: produces antibodies
Outside the cell

8. Parts of the Immune System
Antibody: protein that causes pathogens (antigen) become ineffective
Immunoglobin- antibody found in the blood
Interferon: protein that stops all viruses from reproducing

9. Nonspecific Immune responses are:
Those that are the same every time
Not specific to the pathogen, uses macrophages
Example: Fever, Inflammation, cough , sneeze
Not specific to the pathogen

10. Specific Immunity Response:
Specific to the invader
Detects Antigens (foreign invaders in body)
Produce Immunity
Specific to the invaider

11. Cellular immunity Uses: T cells To destroy: infected body cells
Includes
Cellular immunity
Uses: T cells
To destroy: infected body cells
Humoral Immunity;
Uses: B cells;
To Produce: antibodies
Give: Immunity

12. The body has Specific and Nonspecific Immune Responses (mark an N or S in the flow chart)
Skin: Nonspecific
Mucous Membrane: Nonspecific
Circulatory System: Nonspecific
Phagocyte: Specific
T-cell: Specific
B-cell: Specific
Anibody: Specific
Interferon: Nonspecific

13. Memory Cells
Cells that will remember the antigen and will not allow it to infect the body a second time
Specific immune response

14. Immunity
the ability of an organism to resist a particular infection by the action of specific antibodies or sensitized white blood cells
To be resistant to something due to the body’s response

15. Gained after the body comes in contact with a sickness
Active Immunity
Gained after the body comes in contact with a sickness
Your body works for this

16. Passed through genetics or by injection of antibodies
Passive Immunity
Passed through genetics or by injection of antibodies
This is given to your body

17. prevent future illness if the body becomes infected
Both immunities…
prevent future illness if the body becomes infected

18. Methods to control spread:
Antibiotics:
are medications used to fight infections caused by bacteria pathogens
Work by killing bacteria or slowing and suspending its growth
Many forms:
Tablets, capsules, liquids, creams, ointments
Most require prescription from a doctor

19. Antibiotic Resistance is:
when a population of bacteria or fungi are no longer affected by an antibiotic b/c they have a genetic mutation from the rest of the population

20. Methods Used to Control Pathogens:
Antiseptic: destroys pathogens outside of the body
(soap, hand sanitizer)

21. Methods to control Pathogens
Vaccines
Provides active acquired immunity to a particular disease by injecting a dead or weakened strain of the disease

22. Vaccination Process Stimulates a specific immune response
Causes memory cells to be produced
Allows immune system to respond to an infection without getting sick
Allows for quick response to infection
