What kind of mechanisms does our immune system have to
fight disease?
![Page 10: Catalyst # 3 Pg. 1. 1.What is the scientific name for a white blood cell? 2. 2.What specific types of leukocytes are involved in the inflammatory response?](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970df2/html5/thumbnails/10.jpg)
A. Reminders: Pathogen = any agent (thing) that causes disease.
ex: bacteria, viruses, microbes,
etc. The immune system fights infection by trying to keep you healthy.
![Page 11: Catalyst # 3 Pg. 1. 1.What is the scientific name for a white blood cell? 2. 2.What specific types of leukocytes are involved in the inflammatory response?](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970df2/html5/thumbnails/11.jpg)
B.
There are two ways it does this: 1. Nonspecific Responses2. Specific Responses
![Page 12: Catalyst # 3 Pg. 1. 1.What is the scientific name for a white blood cell? 2. 2.What specific types of leukocytes are involved in the inflammatory response?](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970df2/html5/thumbnails/12.jpg)
1. Nonspecific Defenses
EX: Your skin secretes oil and sweat, which help to kill bacteria (makes the skin acidic, bacteria don’t like to live in these conditions).
Other examples: mucus, tears, inflammation, and fever
Inflammation-when part of the body becomes when part of the body becomes reddened, swollen, hot, and often painfulreddened, swollen, hot, and often painful a reaction to injury or infection.a reaction to injury or infection.
![Page 13: Catalyst # 3 Pg. 1. 1.What is the scientific name for a white blood cell? 2. 2.What specific types of leukocytes are involved in the inflammatory response?](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970df2/html5/thumbnails/13.jpg)
2. Specific Defenses
= ways that your body specifically fights against certain pathogens.
ex: antibodies, produced by white blood cells
![Page 14: Catalyst # 3 Pg. 1. 1.What is the scientific name for a white blood cell? 2. 2.What specific types of leukocytes are involved in the inflammatory response?](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970df2/html5/thumbnails/14.jpg)
If a pathogen is able to get past the body’s nonspecific defenses, the immune system reacts with specific defenses.
Specific defenses that attack the particular pathogen (disease-causing agent) are called immune responses.
This is triggered by an antigen.
2. Continued
![Page 15: Catalyst # 3 Pg. 1. 1.What is the scientific name for a white blood cell? 2. 2.What specific types of leukocytes are involved in the inflammatory response?](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970df2/html5/thumbnails/15.jpg)
3. AntigensWhat is an antigen?
•Anything that triggers an immune response – like an ID card of pathogens (ex: virus, bacteria, other pathogens)
•Each pathogen has its own antigen
![Page 16: Catalyst # 3 Pg. 1. 1.What is the scientific name for a white blood cell? 2. 2.What specific types of leukocytes are involved in the inflammatory response?](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970df2/html5/thumbnails/16.jpg)
4. Antigens on Pathogens
Antigens are how your immune system knows what to attack.
Cells, bacteria, viruses, etc. have special things on them that help your immune system to either recognize them (because they are part of your body) or see that they are invaders and should be attacked.
These protein markers are called: Antigens.
![Page 17: Catalyst # 3 Pg. 1. 1.What is the scientific name for a white blood cell? 2. 2.What specific types of leukocytes are involved in the inflammatory response?](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970df2/html5/thumbnails/17.jpg)
5. To fight against pathogens …
Once your immune system sees that an invading pathogen has antigens (markers/IDs) that it does not recognize, it decides to FIGHT against it!
WHITE BLOOD CELLS create little proteins to recognize the pathogens. These are specific to that certain type of pathogen and help destroy the invaders.
These = ANTIBODIES
![Page 18: Catalyst # 3 Pg. 1. 1.What is the scientific name for a white blood cell? 2. 2.What specific types of leukocytes are involved in the inflammatory response?](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970df2/html5/thumbnails/18.jpg)
6. White Blood Cells
Look for the protein markers (ANTIGENS) on pathogens
When they see a pathogen, they create little proteins to attach to the pathogen
***These proteins that attach to pathogens are called Antibodies****
![Page 19: Catalyst # 3 Pg. 1. 1.What is the scientific name for a white blood cell? 2. 2.What specific types of leukocytes are involved in the inflammatory response?](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970df2/html5/thumbnails/19.jpg)
What are Antibodies? Antibodies are proteins that recognize and bind to antigens (of pathogens)
What do antibodies do? Antibodies are carried in the bloodstream to attach to the pathogen and signal an immune response
As the antibodies overcome the infection, the plasma cells die out and stop producing antibodies
7. Antibodies
![Page 20: Catalyst # 3 Pg. 1. 1.What is the scientific name for a white blood cell? 2. 2.What specific types of leukocytes are involved in the inflammatory response?](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970df2/html5/thumbnails/20.jpg)
Your body produces hundreds of antibodies just in case some happen to fit actual antigens!
* Antibodies have a specific shape and fit with a certain pathogen’s antigen
