Respiratory System
![Page 3: Warm Up Respiratory System Reading and Questions](https://reader035.vdocument.in/reader035/viewer/2022062301/56649dde5503460f94ad64fa/html5/thumbnails/3.jpg)
Functions of the Respiratory System
• Breathing process
• Supplies blood with oxygen (inhale)
• Remove carbon dioxide from cells (exhale)
• Enable speech production
![Page 4: Warm Up Respiratory System Reading and Questions](https://reader035.vdocument.in/reader035/viewer/2022062301/56649dde5503460f94ad64fa/html5/thumbnails/4.jpg)
Structures of Respiratory System
• upper respiratory tract– nose, mouth, pharynx, epiglottis, larynx and
trachea
• lower respiratory tract– bronchial tree and lungs
![Page 5: Warm Up Respiratory System Reading and Questions](https://reader035.vdocument.in/reader035/viewer/2022062301/56649dde5503460f94ad64fa/html5/thumbnails/5.jpg)
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

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

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
![Page 49: Warm Up Respiratory System Reading and Questions](https://reader035.vdocument.in/reader035/viewer/2022062301/56649dde5503460f94ad64fa/html5/thumbnails/49.jpg)

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
![Page 52: Warm Up Respiratory System Reading and Questions](https://reader035.vdocument.in/reader035/viewer/2022062301/56649dde5503460f94ad64fa/html5/thumbnails/52.jpg)

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.
![Page 55: Warm Up Respiratory System Reading and Questions](https://reader035.vdocument.in/reader035/viewer/2022062301/56649dde5503460f94ad64fa/html5/thumbnails/55.jpg)
Common Treatment
Inhaler – works to open airway
![Page 56: Warm Up Respiratory System Reading and Questions](https://reader035.vdocument.in/reader035/viewer/2022062301/56649dde5503460f94ad64fa/html5/thumbnails/56.jpg)

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.
