  4. 4. 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.
  5. 5. 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.
  6. 6. Where are we? Nasal Passage Bronchi Tubes Alveoli (air-sacs) Thin-walled blood vessels called capillaries Very thin cells line the alveoli so that O2 and CO2 can pass in and out of Bronchioles pass air to and from your alveoli. The Trachea is held open by partial rings of cartilage. Tongue Pharynx Here We Go!!!
  7. 7. Here is a overview picture of the Respiratory System. Just go to the next slide to see it. Picture Intro
  8. 8. Respiratory Overview Picture Nasal Cavity Nose Mouth Bronchus Bronchiole Alveolus Diaphragm Throat (pharynx) Windpipe (Trachea) Left lungs Ribs
  9. 9. Now we will begin our tour. Welcome to…
  10. 10. 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
  11. 11. 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.
  12. 12. Nose and Mouth Picture Nasal Cavity Nostril Oral Cavity Pharyn x Here is a picture of your nasal and oral cavity.
  13. 13. Where are We? Nasal Passage Bronchi Tubes Alveoli (air-sacs) Thin-walled blood vessels called capillaries Very thin cells line the alveoli so that O2 and CO2 can pass in and out of the blood. Bronchioles pass air to and from your alveoli. The Trachea is held open by partial rings of cartilage. Tongue Pharynx We are here. Larynx Airway
  14. 14. 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.
  15. 15. 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. Pharynx (Throat) Mouth Trachea
  16. 16. Nasal Passage Bronchi Tubes Alveoli (air-sacs) Thin-walled blood vessels called capillaries Very thin cells line the alveoli so that O2 and CO2 can pass in and out of Bronchioles pass air to and from your alveoli. The Trachea is held open by partial rings of cartilage. Tongue Pharyn x Where are We? We are here.
  17. 17. Your trachea (windpipe) splits up into two bronchi tubes. These two tubes keep splitting up and form your bronchiole. The Bronchi Tubes and Bronchiole Intro
  18. 18. 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…
  19. 19. Alveoli and Bronchi Picture Trachea Bronchi Tubes Bronchiole Alveoli Air Sacks
  20. 20. Oesophagus Nasal Passage Bronchi Tubes Alveoli (air-sacs) Thin-walled blood vessels called capillaries Very thin cells line the alveoli so that O2 and CO2 can pass in and out of Bronchioles pass air to and from your alveoli. The Trachea is held open by partial rings of cartilage. Tongue Pharynx Where are We? Where are5 We? We are here.
  21. 21. Now we will head over to the alveoli and what happens when the air finally makes it down there. The Alveoli and Capillary Network
  22. 22. 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.
  23. 23. Alveoli Picture Here is a close up picture of your Alveoli and a Capillary surrounding it. Capillary Red Blood Cell Oxygen is picked up Carbon Dioxide is dropped off Wall of the air sac
  24. 24. Nasal Passage Bronchi Tubes Alveoli (air-sacs) Thin-walled blood vessels called capillaries Very thin cells line the alveoli so that O2 and CO2 can pass in and out of the blood. Bronchioles pass air to and from your alveoli. The Trachea is held open by partial rings of cartilage. Tongue Pharyn x Where are We? We are here.
  25. 25. Alveolus Bronchiole Respiratory Bronchiole Alveolar Duct Capillaries
  26. 26. Looking at the Alveoli Lets take a closer look.
  27. 27. 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
  28. 28. Diffusion Oxygen Carbon Dioxide Alveolus Contiguous Basal Laminae Capillary Go to next slide to get more detail. Oxygen diffuses through the me rane into the blood stream. Carbon Dioxide diffuses through the membrane and enters the alveolus.
  29. 29. Cool pictures
  30. 30. I n t r o t o D i a p h r a g m Now we will look at the Diaphragm. You might be wondering, what does the Diaphragm do? The Diaphragm is an important factor in breathing.
  31. 31. Diagram of Diaphragm
  32. 32. Here is an experiment that you can try.Diaphragm Experiment
  33. 33. 1st you need a bottle that you can sacrifice to cut up. 2nd you cut the bottom of the bottle and put a big balloon on the bottom. 3rd get a rubber cork ( make sure it blocks the hole)and put a hole through it ( top to bottom). Insert a thin tube into the cork and place a balloon on the bottom of the tube. 4th make sure the thing is airtight. Experiment Instructions
  34. 34. The Pharynx, or throat, is located where passages from the nose and mouth came together. 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 At the end of the bronchioles are bunches of alveoli, air sacs, arranged like grapes on a stemAir enters the trachea, or wind pipe which leads to and from the lungs The trachea divides into two tubes called bronchi If one lobe is injured or diseased, the other lobes may be able to function normally
  35. 35. Fun Facts rest, the body takes in and breathes out about 10 liters of air each nute. e right lung is slightly larger than the left. e highest recorded "sneeze speed" is 165 km per hour. e surface area of the lungs is roughly the same size as a tennis court. he capillaries in the lungs would extend 1,600 kilometers if placed end end. lose half a liter of water a day through breathing. This is the water por we see when we breathe onto glass. person at rest usually breathes between 12 and 15 times a minute. e breathing rate is faster in children and women than in men.
  36. 36. Key Words Cont.  Bronchi Tubes- Each tube (one per lung) splits up into many smaller tubes called Bronchiole, like branches on a tree.  Bronchiole- Keep splitting up until they reach your Alveoli.  Respiratory Bronchiole- The air-tubes that are actually connected to the Alveoli.  Alveolar Duct- The final tube, which is part of the Alveoli, that leads to the air-sacs.  Alveolar Sac- Where the chemical change takes place and where blood cells pick up oxygen and drop off carbon dioxide.  Alveoli- Tiny air-sacs at the end of your Alveolar Duct. They fill up with Oxygen and are surrounded by Capillaries.  Capillaries- Tiny blood streams (around one cell wide) that surround your Alveoli. They take Oxygen out of our Lungs and replace it with Carbon Dioxide, which you later breath out.  Diaphragm- The muscle membrane that helps you breath in and out by changing the pressure in your chest cavity.
  37. 37. The End So Take a Deep Breath and THANKS
