Respiratory System Reading and Questions

2. Respiratory System

3. Functions of the Respiratory System
Breathing process
Supplies blood with oxygen (inhale)
Remove carbon dioxide from cells (exhale)
Enable speech production

4. Structures of Respiratory System
upper respiratory tract
nose, mouth, pharynx, epiglottis, larynx and trachea
lower respiratory tract
bronchial tree and lungs

5. Frayer Model “competition”
With your group, you will complete sets of Frayer models using the textbook and a handout
You will have 15 minutes per page
At the end of time, your group with get points
Completing all parts of each Frayer model = 1 point
Having correct information in each Frayer model = 2 points
Group working together = 2 points

6. Characteristics You will not find a sentence that says….
“The characteristics are ….”
A characteristics is something that describes something else (normally an adjective)

7. Frayer Models Respiratory System Oxygen Mouth, Nose & Nasal Cavity
Nasal Mucus & Cilia

8. Respiratory System
Definition: the body system that’s function is to get oxygen from the environment and remove carbon dioxide from your body
Characteristics: very important to human life
Importance: brings oxygen into the body and humans cannot live without oxygen
Parts: mouth, nose, nasal cavity, Trachea, Epiglottis, lungs

9. Oxygen Definition: an important gas human’s need to live
Characteristics: essential to human life, taken from the air around us
Importance: without oxygen you would die
Non-Example: carbon Dioxide

10. Mouth, Nose and Nasal Cavity
Definition: the way air enters the respiratory system; the first place air goes in the body
Characteristics: on your head
Importance: we need them so that we can inhale oxygen
Non-Example: Ear

11. Nasal Mucus and Cilia
Definition: mucus = a sticky liquid, Cilia = little nose hairs
Characteristics: inside your nose
Importance: help trap dirt and germs

12. Frayer Models
Trachea (35)
Epiglottis (35)
Pharynx
Larynx

13. Trachea
Definiton: the tube that connects the upper respiratory system (mouth & nose) to lungs
Job: separates the 2 sides of the lungs
Made of cartilage tissue

14. Epiglottis
Definition: a flap of skin that covers the trachea, in the back of your throat above tounge
Why is it important? Stops food or liquid from getting into your lungs
Job: Stops food or liquid from getting into your lungs
Picture

15. Pharynx
Definition: area behind the nose that leads to the throat – controls the amount of air that gets into your lungs.
Picture:
Why do you think it is important?
to make sure too much air doesn’t go down into your lungs and pop them

17. Larynx
Definition: also called voicebox, contains cords that vibrate to produce sound
Characteristic: at the bottom of the Pharynx
Importance: Without a Larynx you would not be able to talk

18. Warm Up – put HW on desk Copy sentences and fill in the blanks.
The Respiratory System is important because it controls ___________, which humans must do to stay alive.
The ____________ is the part of the Respiratory System that stops food from getting into our lungs.

19. Warm Up
The Respiratory System is important because it controls BREATHING, which humans must do to stay alive.
The EPIGLOTTS is the part of the Respiratory System that stops food from getting into our lungs.

20. Frayer Models Lungs (39) Bronchial Tubes (40B and 39)
Alveoli (39 and 40B)
Diaphragm (40B)
cross out picture and write “JOB”
Cross out non-example and write location

21. Lungs Definition: the main organ of the respiratory system,
most complicated
Look like: a tree
Number: a human has a pair
a lungs (2)- one on each side of heart

22. Lungs
trachea

23. Bronchial Tubes Definition: 2 braches/tubes of the lungs
Characteristics: carry air into each lung, have thousands of little branches or “twigs”
Picture:
Location- inside the lungs

24. Alveoli Definition: small sacs that fill with air when we breath in.
Characteristic: very small, like a balloon
Job: Put oxygen into blood and take out carbon dioxide
Location: at the end of each bronchial tube/twig

26. Diaphragm
Definition: a large muscle that stretches across the floor of the thoracic cavity (lungs)
Characteristics: very big, strong, important
Importance: allows you to breathe in and out
How it works: diaphragm contracts (get flat) = air flows in lungs, inhale
diaphragm expands (puffs up) = air flows out of lungs, exhale

28. The Path Oxygen takes through the body
Now that you have all of the definitions, you must know the order/path oxygen takes throughout the body
Diagram

29. The Path Oxygen Take Throughout the Body
Mouth / Nose
Pharynx
Larynx
Trachea
Bronchial Tubes
Lungs
Alveoli

30. Mouth / Nose The only 2 places that oxygen can enter the body
Nose contains cilia and mucus to trap dirt and germs

31. 2. Pharynx Behind nose, leads to throat
- Controls the amount of air that enters the lungs

32. 3. Larynx Below Pharynx Also called Voice box
Produces sounds, uses oxygen to vibrate cords and make noises

33. 4. Trachea AKA Windpipe Covered by the Epiglottis
Tube that carries oxygen towards the lungs

34. 5. Bronchial Tubes 2 braches/tubes that carry air into each lung
Branch out into several more “twigs”

35. 6. Lungs
Look like a tree
Take oxygen in And carbon dioxide out of the body

36. 7. Alveoli Inside lungs, on the end of the Bronchial Tubes’ twigs
Put oxygen into blood
Take out carbon dioxide

37. Diagram Glue, Staple or Tape diagram to the back of the foldable

46. Asthma
What is it? a condition that affects a person's bronchial tubes/airways.

48. Asthma There are 3 things that happen to people with Asthma
1. Inflammation of airways, (tubes get smaller)
2. Bronco constriction – tightening of muscles
3. Increase in mucus production
All of these things make it harder for oxygen to get through to lungs

51. What causes it?
Different people have different triggers — things that set off asthma flare-ups
dust mites (tiny bugs that live in dust)
mold
Pollen
Animals
perfume, chalk dust, and cigarette smoke
Exercise

54. How is it treated?
Not every kid's asthma is the same, so there are different medicines for treating it.
It's not like curing a sore throat or an earache, when everybody gets the same medicine. Instead, the doctor will think about what causes the asthma flare-ups, how fast the flare-ups happen, and how serious they are. Then he or she will decide on the best kind of treatment.

55. Common Treatment
Inhaler – works to open airway

57. How do you help? Help them get into a comfortable sitting position.
Many asthma patients carry not only an inhaler, but a written instruction card as well. An asthma attack can temporarily rob the patient of his ability to speak.
* Help them use the inhaler. An inhaler is designed to deliver a specific dose of asthma medication. The medication relaxes the patient's airways and helps restore normal breathing.
* If it appears that they are not responding to the medication within ten minutes, call an ambulance. And continue to deliver about four puffs of medication every five minutes while waiting for the ambulance.
The medication will help prevent the asthma attack from getting worse even if it doesn't seem to provide immediate relief.
* Stay calm throughout the episode. This will help the patient remain calm as well. If he panics, it will worsen the asthma attack and make it far more difficult for him to breathe.
