1 Respiratory System 6 th Grade Health with Mr. Springer

2 Functions/Jobs Take oxygen into the body & Eliminate carbon dioxide from the body

3 Introduction Activity Why couldn’t we go for more than a couple minutes without air? If you can go days without food and water…

4 Exhaling and Inhaling

5 Vocabulary Mouth: Air enters the body through either the open mouth or the nose. It travels down the trachea to the lungs, where the oxygen in it passes into the bloodstream.

6 Vocabulary (cont) Nasal passage: Air enters the body through either the open mouth or the nose. Tiny hairs in the nose trap unwanted particles while a sticky liquid called mucus catches many of the germs before they can go too far into the respiratory system. Mucus also warms and moistens the air.

7 Vocabulary (cont) Trachea (Windpipe): About half of its 13 cm length is inside the chest and the other half is in the neck. The lower end of the trachea divides into two bronchi (tubes) that carry air into the lungs. Bronchi: The lower end of the trachea divides into two bronchi (tubes) that carry air into the lungs. One bronchus goes to the left lung, the other to the right lung.

8 Vocabulary (cont) Bronchioles: Each bronchus divides into smaller and smaller tubes called bronchioles. Alveoli: Bronchioles eventually lead to tiny, stretchy sacs called alveoli. These sacs blow up like tiny balloons when you breathe in. Oxygen from the air passes through the walls of the alveoli into capillaries while carbon dioxide is passed out.

9 Vocabulary (cont) Lung: Balloon-like structures in the chest that bring oxygen into the body and expel carbon dioxide from the body. Diaphragm: The diaphragm is a strong muscle just below the lungs. When your breathe in and out, the diaphragm moves downwards and upwards against the lungs.

10 A Look at the Diaphragm

11 Vocabulary (cont) Epiglottis: A flap in the throat that blocks the windpipe when food or liquid is being swallowed.

12 A look Into the Lungs

13 A Human Lung!

15 Lung Conditions We will now begin talking about the negative affects smoking can have on your lungs, and about lung diseases.

16 Lung Cancer

17 Healthy Lung

18 Facts about Smoking Hurting Yourself Smoking is an addiction. Tobacco smoke contains nicotine, an addictive drug that can make it very hard, but not impossible, to quit. More than 400,000 deaths in the U.S. each year are from smoking-related illnesses. Smoking greatly increases your risks for lung cancer and many other cancers.

19 Facts about Smoking (cont) Hurting Others Smoking harms not just the smoker, but also family members, coworkers and others who breathe the smoker's cigarette smoke, called secondhand smoke. Among infants to 18 months of age, secondhand smoke is associated with as many as 300,000 cases of bronchitis and pneumonia each year. Secondhand smoke from a parent's cigarette increases a child's chances for middle ear problems, causes coughing and wheezing, and worsens asthma conditions.

20 Facts about Smoking (cont) Hurting Others If both parents smoke, a teenager is more than twice as likely to smoke than a young person whose parents are both non-smokers. In households where only one parent smokes, young people are also more likely to start smoking. Pregnant women who smoke are more likely to deliver babies whose weights are too low for the babies' good health. If all women quit smoking during pregnancy, about 4,000 new babies would not die each year.

21 Facts about Smoking Why Quit? Quitting smoking makes a difference right away - you can taste and smell food better. Your breath smells better. Your cough goes away. This happens for men and women of all ages, even those who are older. It happens for healthy people as well as those who already have a disease or condition caused by smoking. Quitting smoking cuts the risk of lung cancer, many other cancers, heart disease, stroke, other lung diseases, and other respiratory illnesses.

22 Facts about Smoking Why Quit? Ex-smokers have better health than current smokers. Ex-smokers have fewer days of illness, fewer health complaints, and less bronchitis and pneumonia than current smokers. Quitting smoking saves money. A pack-a-day smoker, who pays $2 per pack can, expect to save more than $700 per year. It appears that the price of cigarettes will continue to rise in coming years, as will the financial rewards of quitting.

23 Asthma Asthma is a disease that affects your lungs and airways, and your life During an Asthma Attack: The lining of your lungs and airways become inflamed (swollen) Muscles around your airways tighten, causing your airways to narrow

24 During An Asthma Attack… Your body produces too much mucus, which can clog your airways Your airways become overly sensitive to irritants …All of this limits air flowing into and out of your lungs, and makes it hard to breathe. This results in asthma symptoms: coughing, wheezing, shortness of breath, and tightness in the chest.

25 Asthma (cont) Common triggers of an asthma attack include: (they can be different for everyone) Cigarette smoke Cockroaches Dust mites Mold Pets and animals Pollen Cold air Exercise Stress Respiratory infections

26 Other Lung Conditions Other Respiratory System Conditions/Diseases: Cystic Fibrosis Tuberculosis Cancer Influenza Pneumonia
