  1. Oxygen Cell Hi I am O2 ,you can call me oxygen, and I will be your guide today. I advise you keep all feet and hands inside the ride at all times. JH

  2. Now we will begin our tour. Welcome to… Welcome The Respiratory System MB

  3. Respiratory Intro You may be asking, what is the Respiratory system? Well, the Respiratory system is the system that helps you breath in and out, so oxygen (02) can be pumped through your body and carbon dioxide (CO2) can be removed from the blood stream. You must remember that the Respiratory system is made up of many different organs. JH

  4. Picture Intro Here is a overview picture of the Respiratory System. Just go to the next slide to see it. MB

  5. Nasal Cavity Throat (pharynx) Nose Mouth Windpipe (Trachea) Bronchus Left lungs Bronchiole Ribs Alveolus Diaphragm Respiratory Overview Picture MB

  6. Where are we? Nasal Passage Tongue Pharynx Bronchi Tubes The Trachea is held open by partial rings of cartilage. Alveoli (air-sacs) Thin-walled blood vessels called capillaries Bronchioles pass air to and from your alveoli. Very thin cells line the alveoli so that O2 and CO2 can pass in and out of the blood. Here We Go!!! JH

  7. This is where it all begins. This is where the oxygen first enters your body and also where Carbon Dioxide leaves. The Nose and Mouth MB

  8. The Nose and Mouth When the air comes into your nose it gets filtered by tiny hairs and it is moistened by the mucus that is in your nose. Your sinuses also help out with your Respiratory System. They help to moisten and heat the air that you breath. Air can also get into your body through your mouth/oral cavity but air is not filtered as much when it enters in through your mouth. MB

  9. Nose and Mouth Picture Nasal Cavity Nostril Oral Cavity Pharynx Here is a picture of your nasal and oral cavity. MB

  10. Nasal Passage Tongue Pharynx Bronchi Tubes The Trachea is held open by partial rings of cartilage. Alveoli (air-sacs) Thin-walled blood vessels called capillaries Bronchioles pass air to and from your alveoli. Very thin cells line the alveoli so that O2 and CO2 can pass in and out of the blood. Where are We? We are here. MB

  11. The Pharynx and Trachea Next we will head down to your pharynx (throat) and your trachea (windpipe). This is where the air passes from your nose to your bronchi tubes and lungs. MB

  12. Mouth Pharynx (Throat) Trachea The Pharynx and Trachea Your pharynx (throat) gathers air after it passes through your nose and then the air is passed down to your trachea (windpipe). Your trachea is held open by “incomplete rings of cartilage.” Without these rings your trachea might close off and air would not be able to get to and from your lungs. MB

  13. Nasal Passage Tongue Pharynx Bronchi Tubes The Trachea is held open by partial rings of cartilage. Alveoli (air-sacs) Thin-walled blood vessels called capillaries Bronchioles pass air to and from your alveoli. Very thin cells line the alveoli so that O2 and CO2 can pass in and out of the blood. Where are We? We are here. MB

  14. The Bronchi Tubes and Bronchiole Intro Your trachea (windpipe) splits up into two bronchi tubes. These two tubes keep splitting up and form your bronchiole. MB

  15. The Bronchi Tubes and Bronchiole These bronchi tubes split up, like tree branches, and get smaller and smaller inside your lungs. The air flows past your bronchi tubes and into your bronchiole. These tubes keep getting smaller and smaller until they finally end with small air sacs (called alveoli). But we will go there later… MB

  16. Alveoli and Bronchi Picture Trachea Bronchi Tubes Bronchiole Alveoli MB

  17. Nasal Passage Tongue Pharynx Bronchi Tubes The Trachea is held open by partial rings of cartilage. Alveoli (air-sacs) Thin-walled blood vessels called capillaries Bronchioles pass air to and from your alveoli. Very thin cells line the alveoli so that O2 and CO2 can pass in and out of the blood. Where are We? We are here. MB

  18. The Alveoli and Capillary Network Now we will head over to the alveoli and what happens when the air finally makes it down there. MB

  19. The Alveoli and Capillary Network Your alveoli are tiny air sacs that fill up with air/oxygen when you breath in. Your alveoli are surrounded by many tiny blood vessels called capillaries. The walls of your alveoli (and capillaries) are so thin that the oxygen or carbon dioxide can pass through them, traveling right into, or out of your blood stream. MB

  20. Capillary Carbon Dioxide is dropped off Wall of the air sac Oxygen is picked up Red Blood Cell Alveoli Picture Here is a close up picture of your Alveoli and a Capillary surrounding it. MB

Alveoli (air-sacs) Thin-walled blood vessels called capillaries Bronchioles pass air to and from your alveoli. Very thin cells line the alveoli so that O2 and CO2 can pass in and out of the blood. Where are We? We are here. MB

  22. Alveolus Bronchiole Respiratory Bronchiole Alveolar Duct Alveolar Sac Capillaries Alveolus JH

  23. Looking at the Alveoli Lets take a closer look shall we. JH

  24. Chemicals Red blood cell carrying Carbon dioxide Chemical change is taking place in cell Red blood cell carrying oxygen Alveolus Contiguous Basal Laminae (Membrane) Capillary JH

  25. Diffusion Oxygen Carbon Dioxide Oxygen diffuses through the membrane into the blood stream. Carbon Dioxide diffuses through the membrane and enters the alveolus. Alveolus Contiguous Basal Laminae (Membrane*) Capillary * A specialized thin layer of skin that oxygen and carbon dioxide can pass through. JH

  26. Cool pictures JH

  27. Intro to Diaphragm Now we will look at the Diaphragm. You might be wondering, what does the Diaphragm do? The Diaphragm is an important factor in breathing. JH

  28. Diagram of Diaphragm JH

  29. Diaphragm Experiment Here is an experiment that you can try. JH

  30. CO2 Air Passing over the mucus membrane of the nasal cavity is moistened, warmed, and filtered Inside the lungs the Bronchi branch into small tubes called bronchioles The Pharynx, or throat, is located where passages from the nose and mouth came together. Respiratory Overview Review At the end of the bronchioles are bunches of alveoli, air sacs, arranged like grapes on a stem Air enters the trachea, or wind pipe which leads to and from the lungs If one lobe is injured or diseased, the other lobes may be able to function normally The trachea divides into two tubes called bronchi JH

  31. Fun Facts * At rest, the body takes in and breathes out about 10 liters of air each minute. * The right lung is slightly larger than the left. * The highest recorded "sneeze speed" is 165 km per hour. * The surface area of the lungs is roughly the same size as a tennis court. * The capillaries in the lungs would extend 1,600 kilometers if placed end to end. * We lose half a liter of water a day through breathing. This is the water vapor we see when we breathe onto glass. * A person at rest usually breathes between 12 and 15 times a minute. * The breathing rate is faster in children and women than in men.
