1. The Respiratory System
Keynote Presentation
by Jamie York

2. True or False
You can live longer without food and water than you can without oxygen?

3. You can only live a few minutes if your body doesn’t have oxygen!
True
You can only live a few minutes if your
body doesn’t have oxygen!
Why?

4. Your body cannot store oxygen like it can store food
Your body cannot store oxygen like it can store food * You must provide your body with fresh oxygen all the time!

5. Body Systems Respiratory Skeletal Muscular Circulatory Digestive
Excretory
Endocrine
Nervous

6. You will learn: The main parts of the Respiratory System
The jobs of the Respiratory System
What breathing and Respiration are all about
Ways you can prevent damage to your Respiratory System

7. Who “nose” the parts of the Respiratory System?

8. NOTE A: Each air sac is covered with tiny blood vessels (CAPILLARIES)
NOTE A: Each air sac is covered with tiny blood vessels (CAPILLARIES). Oxygen moves from air sacs into capillaries. Carbon dioxide moves in the opposite direction. Red blood cells transport these gases to and from all the cells in our body.
NOTE B: If too much mucus is made then the passage way gets smaller and air has a harder time to get through. This can happen in chronic bronchitis and asthma.
NOTE C: Air flows from bronchioles into millions of tiny air sacs called ALVEOLI. The sacs look like bunches of grapes at the end of the bronchial tubes. The alveoli are where the oxygen from the air enters your blood, and the carbon dioxide from your body goes into the air. Alveoli are very tiny, but you have a lot of them in your lungs. In fact, you have 300,000,000 alveoli in each lung. That's six hundred million in total - and your body needs them all to get enough oxygen in your blood!

9. The Respiratory System has two main jobs:
Provide oxygen for the body
Remove gaseous wastes from the body

10. The Circulatory and Respiratory Systems work together to
get the jobs done!
Can you explain how?
Take a deep breath and think about it.

11. Let’s break down the process:
Breathing - oxygen is inhaled
Circulation - oxygen is carried to the cells
Respiration - oxygen and sugar combine in a chemical reaction to release ENERGY
Circulation - carbon dioxide is carried to the lungs
Breathing - carbon dioxide is exhaled

12. After all, the system has been named for it!
What is respiration?
After all, the system has been named for it!

13. A process that takes place in the cells of your body.
Respiration is...
A process that takes place in the cells of your body.
Oxygen combines with sugar, and ENERGY is released! Carbon dioxide and water are produced as wastes.

14. “That’s too much information! Why do I need to understand that?”
YAWN!
“That’s too much information!
Why do I need to understand that?”

15. Yawning is your bodies way of releasing extra carbon dioxide.
You need to understand that Your brain controls breathing by sensing the amount of carbon dioxide in your body.
For example:
Yawning is your bodies way of releasing extra carbon dioxide.

16. Think about this... Why do you breath harder when you run?

17. releases carbon dioxide
Your muscles need more
oxygen to work hard.
Breathing harder
releases carbon dioxide
and brings in
more oxygen quickly!

18. What if we run out of oxygen?!

19. If we care for the plant life in our environment, we won’t!
* Plants release the oxygen we need through photosynthesis, and we release the carbon dioxide they need when we breath.

20. What can harm the Respiratory System?
Bacteria & Viruses
Asthma & Allergies
Polluted & Smoke-filled air
* Respiratory System problems can become serious quickly. YOU NEED OXYGEN TO SURVIVE!

21. Keep your Respiratory System healthy!
Exercise regularly
Avoid polluted air
NEVER smoke!
