 What are the four parts of blood?
Respiration
One Oxygen Filled Breath at a Time

 How does my respiratory system and
circulatory system work together?
Respiratory System
 A collection of organs whose primary
function is to take in oxygen and expel
carbon dioxide.
Breathing
 When I breathe in
air, I bring in oxygen
to my lungs.
 They end up in tiny
air sacs called alveoli.
 I have about 300
million alveoli.
Alveoli
 Any of the tiny air sacs of the lungs where
oxygen and carbon dioxide are exchanged.
Inside Alveoli
 When oxygen is breathed in, it ends up in
my alveoli where my red blood cells
exchange it for carbon dioxide.
Reflection Question 11-05-09
 What might
happen if half of
your alveoli didn’t
work?
 Share with a
partner and be
ready to debrief.

my 300 million
alveoli?
Visual Concepts: Respiration
 Watch and participate as Mr. Wager walks
you through some visual concepts that show
how your lungs and respiration works.
Human Machine: Respiration
 Follow along as we echo read from the
Human Machine book and write
questions to correspond with the text.
Respiratory Disorders
 Asthma is a condition where your lungs are
full of too much mucus, making it difficult
for oxygen to reach your alveoli.
 The tubes in your lungs are also narrowed.
Respiratory Disorders
 Smoking fills my alveoli up with sticky tar
and can kill some. This makes them
unusable, which means I get less oxygen
in my blood.
Respiratory Disorders
 Smoking will also
add chemicals to my
lungs that can lead
to cancer and a
disease called
emphysema.
Healthy Lung
No Smoking Please
Reflection Question 11-06-09
 Write a letter to a loved one either telling
them why you won’t start smoking, or why
they need to stop smoking.

 What are some jobs of my blood?
Breathing with Emphysema
1. Take the coffee stirrer and put it on your lips.
2. IFYOU USE IT TO SPIT ANYTHINGWITH,YOUWILL

through this straw.
IFYOU FEEL LIGHT HEADED OR SICK AT ANY POINT,
STOP IMMEDIATELY.
Answer the address the following:
Describe how you felt as time went by.
Why do people with emphysema feel this way?
Benefits From Quitting Smoking
 The American Cancer Society lists some of the immediate and

long-term health benefits of quitting smoking:
After 20 minutes, blood pressure drops to normal.
After 8 hours, the carbon monoxide level in the blood drops to
normal.
After 48 hours, nerve endings start re-growing and the senses of
smell and taste are enhanced.
In one to nine months, coughing, sinus congestion, fatigue, and
shortness of breath decrease and cilia (tiny, hair like cells that
move continually to clean air that is breathed in) re-grow in the
lungs.
After five years, the chance of dying from lung cancer decreases
by almost half.
After 15 years, the risk of heart disease is equal to that of a
nonsmoker, and the risk of dying from lung cancer is only slightly
higher than that of a non smoker.
Smoking Letter
 Write a letter and address it to someone you know.
 You must either tell them why you won’t smoke, or
why they should stop smoking.
 You must use at least three facts from the “Smoking
Facts” sheet.
 You must use the words:
 Addiction
 Tar
 Alveoli.

Roughly 6 million teens in the US today smoke despite
the knowledge that it is addictive and leads to disease.
About 3,000 teens will start smoking today and nearly
1,000 will eventually die as a result from smoking.
Although only 5 percent of high school smokers said
that they would definitely be smoking five years later,
close to 75 percent were still smoking 7 to 9 years later.
A person who starts smoking at age 13 will have a
more difficult time quitting, has more health-related
problems and probably will die earlier than a person
who begins to smoke at age 21.
Kids who smoke have reduced lung growth, and don’t
achieve normal lung function as an adult.

More than 90 percent of adult smokers started
when they were teens.
Kids who have parents who smoke are more than
twice as likely to smoke as kids without parents
who smoke
3,000 nonsmoking adults die of diseases caused by
exposure to second hand smoke every year.
Secondhand smoke causes coughing, phlegm and
reduced lung function in nonsmokers.
Secondhand smoke contains more than 4,000
chemical compounds.
