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

  2. Respiration One Oxygen Filled Breath at a Time

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

  4. Respiratory System • A collection of organs whose primary function is to take in oxygen and expel carbon dioxide.

  5. 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.

  6. Alveoli • Any of the tiny air sacs of the lungs where oxygen and carbon dioxide are exchanged.

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

  8. 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.

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

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

  11. Human Machine: Respiration • Follow along as we echo read from the Human Machine book and write questions to correspond with the text.

  12. 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.

  13. 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.

  14. Respiratory Disorders • Smoking will also add chemicals to my lungs that can lead to cancer and a disease called emphysema.

  15. Healthy Lung

  16. No Smoking Please

  17. 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.

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

  19. Breathing with Emphysema • Take the coffee stirrer and put it on your lips. • If you use it to spit anything with, you will have a detention and referral. • For the next minute, you can only breathe through this straw. • If you 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?

  20. 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.

  21. 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.

  22. Smoking Facts • 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.

  23. Smoking Facts • 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.

  24. Science Starter 11-10-09 • What happens with my red blood cells in my capillaries?

  25. Science Starter 11-11-09 • Describe the relationship between your circulatory and respiratory systems? How do they work together?
