3. Oxygen Cell Hi I am O 2,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.

4. Respiratory Intro what is the Respiratory system? Well, the Respiratory system is the system that helps you breath in and out, so oxygen (0 2 ) can be pumped through your body and carbon dioxide (CO 2 ) can be removed from the blood stream. You must remember that the Respiratory system is made up of many different organs.

5. Where are we? Nasal Passage Bronchi Tubes Very thin cells line the alveoli so that O 2 and CO 2 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. Here We Go!!! JH

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

8. Welcome Now we will begin our tour. Welcome to…

9. 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

10. When the air comes into your nose it gets filtered by tiny hairs Air can also get into your body through your mouth

12. Nasal Passage Bronchi Tubes Alveoli (air-sacs) Thin-walled blood vessels called capillaries Very thin cells line the alveoli so that O 2 and CO 2 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 Where are We? We are here.

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

14. The Pharynx and Trachea Your (throat) gathers air and passed down to your trachea. Pharynx (Throat) Mouth Trachea

15. Nasal Passage Bronchi Tubes Alveoli (air-sacs) Thin-walled blood vessels called capillaries Very thin cells line the alveoli so that O 2 and CO 2 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 Where are We? We are here.

16. Your trachea (windpipe) splits up into two bronchi tubes. The Bronchi Tubes

17. These bronchi tubes split up, like tree branches, and get smaller and smaller inside your lungs. The air flows past your bronchi tubes

18. Alveoli and Bronchi Picture Trachea Bronchi Tubes Bronchiole Alveoli

19. Nasal Passage Bronchi Tubes Alveoli (air-sacs) Thin-walled blood vessels called capillaries Very thin cells line the alveoli so that O 2 and CO 2 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 Where are We? We are here.

20. Now we will head over to the alveoli and what happens when the air finally makes it down there.

21. Capillary Red Blood Cell Oxygen is picked up Carbon Dioxide is dropped off Wall of the air sac
