Respiratory System

Warm Up
• Respiratory System Reading and Questions
Respiratory System
Functions of the Respiratory
Breathing process
Supplies blood with oxygen (inhale)
Remove carbon dioxide from cells (exhale)
Enable speech production
Structures of Respiratory System
• upper respiratory tract
– nose, mouth, pharynx, epiglottis, larynx and
• lower respiratory tract
– bronchial tree and lungs
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
– Group working together = 2 points
• You will not find a sentence that says….
“The characteristics are ….”
A characteristics is something that describes
something else (normally an adjective)

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
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
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
Non-Example: Ear
Nasal Mucus and Cilia
Definition: mucus = a sticky liquid, Cilia = little
nose hairs
Characteristics: inside your nose
Importance: help trap dirt and germs
Frayer Models
Trachea (35)
Epiglottis (35)
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
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
Definition: area behind the nose that leads to the
throat – controls the amount of air that gets into
your lungs.
Why do you think it is important?
to make sure too much air doesn’t go
down into your lungs and pop them
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
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.
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.

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
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
Bronchial Tubes
Definition: 2 braches/tubes
of the lungs
Characteristics: carry air into
each lung, have thousands
of little branches or
Location- inside the lungs
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
Location: at the end of each bronchial tube/twig
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

• Now that you have all of the definitions,
you must know the order/path oxygen takes
throughout the body

Nose contains cilia and mucus to trap dirt and
2. Pharynx
Behind nose, leads to throat

3. Larynx
Below Pharynx
Also called Voice box
Produces sounds, uses oxygen to vibrate cords
and make noises
4. Trachea
• AKA Windpipe
• Covered by the Epiglottis
• Tube that carries oxygen towards the lungs
5. Bronchial Tubes
2 braches/tubes that
carry air into each
Branch out into several
more “twigs”
6. Lungs
Look like a tree
Take oxygen in And carbon dioxide out of the
7. Alveoli
Inside lungs, on the end of the Bronchial
Tubes’ twigs
Put oxygen into blood
Take out carbon dioxide

Extra credit – Diaphragm
What is it? a condition that affects a person's
bronchial tubes/airways.
There are 3 things that happen to people with
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
What causes it?
Different people have different triggers — things
that set off asthma flare-ups
dust mites (tiny bugs that live in dust)
perfume, chalk dust, and cigarette smoke
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.
Common Treatment
Inhaler – works to open airway
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.
