4. Our Goal for the day
The EOC is 9 class periods away. WE ARE SMART, WE ARE CAPABLE, AND WE CAN DO THIS!
SWBAT explain how fast disease spreads and how our body responds to it.

5. FLU activity Background Information:
Everyday you exchange bodily fluids with friends, family and COMPLETE STRANGERS.
It can happen from something intimate (like a kiss), polite (like conversation), or meaningless (like touching the same doorknob)
We will simulate this in a brief lab activity.
Expectations:
Move carefully
Maintain water level
You do not get to pick ywho you swap with
FLU activity
One of your classmates has the flu!
I will walk around with the indicator to see how quickly this virus spread, and how many of you are now infected!
If your solution turns purple/black you are ILL!

6. Page 22: Immune Activity Reflections
What preventatives do people take to stop the spread of the flu virus?
What are some common flu-like/ cold symptoms you would expect to experience if you got sick?
What steps might you take to get better (either from the suggestion of a doctor, or homecare)?
#TBT getting ready for the EOC
Why do they have to update the flu vaccine annually (every year)?

7. PAGE 23: IMMUNE SYSTEM NOTES
Let’s take some notes on this topic

8. Pathogens
Our body is a violent place, it is constantly defending against foreign invaders.
These invaders are called pathogens.
Pathogens are disease causing microorganisms that try to enter the body.
Examples?
Common Cold - Rhinovirus
Flu - Orthomyoxovirus
Sore Throat - Streptoccus
HIV - Human Immunodeficiency Virus
What do you notice about these names?

9. Three Types of Pathogens
Bacteria Virus Fungal

10. Bacteria Basics
Bacteria reproduce through binary fission. They can be round (cocci), rod-shaped (bacilli), or corkscrewed (spirilli). They have a thick cell wall (that humans don’t have). TREATMENT: Antibiotics kill bacteria, by attacking parts that bacteria have that humans don’t. They are outside human cells.

11. Virus Basics
Contain genetic material (DNA/RNA), but replicate inside the host cell. They infect human cells. Extremely small (15 nanometers) Treatment: Usually left up to the patient’s own immune system. Vaccines are given of “live” weakened viruses, or “dead” viruses so that body can build up a defense. Also anti-viral drugs.

12. The Immune System The Immune system is our body’s line of defense against pathogens.
It has two ways of fighting against disease:
Specific
Nonspecific
SHOW YOUR SMARTS!
What can we expect about the two responses based on their names?

13. Preventative Defense
Skin
Mucus
Tears

14. Non Specific Defense Fever Inflammation
A Barrier that does not recognize a specific invader
Fever
Inflammation
Macrophages: Eat bacteria or viruses by surrounding them and breaking them down.

15. Specific Defense
A Barrier that does recognize a specific invader.
White Blood Cells are responsible for specific responses.
T-Cells kill the infected cell.
B cells make Antibodies
Markers that attach to the pathogen and mark it for death.
