Science Starter 11-04-09What are the four parts of blood?

One Oxygen Filled Breath at a Time

Respiration

Science Starter 11-05-09How does my respiratory system and circulatory system work together?

Respiratory SystemA collection of organs whose primary function is to take in oxygen and expel carbon dioxide.

BreathingWhen 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.

AlveoliAny of the tiny air sacs of the lungs where oxygen and carbon dioxide are exchanged.

Inside AlveoliWhen oxygen is breathed in, it ends up in my alveoli where my red blood cells exchange it for carbon dioxide.

Reflection Question 11-05-09What might happen if half of your alveoli didn’t work?Share with a partner and be ready to debrief.

Science Starter 11-06-09What is the job of my 300 million alveoli?

Visual Concepts: RespirationWatch and participate as Mr. Wager walks you through some visual concepts that show how your lungs and respiration works.

Human Machine: RespirationFollow along as we echo read from the Human Machine book and write questions to correspond with the text.

Respiratory DisordersAsthma 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 DisordersSmoking 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 DisordersSmoking will also add chemicals to my lungs that can lead to cancer and a disease called emphysema.

Healthy Lung

No Smoking Please

Reflection Question 11-06-09Write a letter to a loved one either telling them why you won’t start smoking, or why they need to stop smoking.

Science Starter 11-09-09What are some jobs of my blood?

Breathing with Emphysema1. Take the coffee stirrer and put it on your

lips.2. IF YOU USE IT TO SPIT ANYTHING WITH, YOU

WILL HAVE A DETENTION AND REFERRAL.3. For the next minute, you can only breathe

through this straw.4. IF YOU FEEL LIGHT HEADED OR SICK AT ANY

POINT, STOP IMMEDIATELY.5. Answer the address the following:6. Describe how you felt as time went by.7. 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 LetterWrite 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: AddictionTar Alveoli.

Smoking Facts1. Roughly 6 million teens in the US today smoke

despite the knowledge that it is addictive and leads to disease.

2. About 3,000 teens will start smoking today and nearly 1,000 will eventually die as a result from smoking.

3. 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.

4. 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.

5. Kids who smoke have reduced lung growth, and don’t achieve normal lung function as an adult.

Smoking Facts6. More than 90 percent of adult smokers

started when they were teens.7. Kids who have parents who smoke are

more than twice as likely to smoke as kids without parents who smoke

8. 3,000 nonsmoking adults die of diseases caused by exposure to second hand smoke every year.

9. Secondhand smoke causes coughing, phlegm and reduced lung function in nonsmokers.

10.Secondhand smoke contains more than 4,000 chemical compounds.
