  2. Human Respiratory System XI Grade Senior High School

  3. Human Respiratory Tract Outline • To understand about definition of respiratory system. • To observe the organs that arrange human respiratory tract. • To explore the mechanism of breathing. • To know the disorder/disease in human respiratory tract.

  5. What is Respiratory System?

  6. 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.

  7. You may be asking, what is the Respiratory system? Respiratory Intro 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

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

  9. What are the components of Human Respiratory System?

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

  11. In general N-P-L-T-B2-Lu-As Nares – Pharynx -Larynx -Trachea-Bronchi-Bronchiole-Lung-Alveolous Sac

  12. 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

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

  14. 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

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

  16. 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

  17. 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

  18. The Pharynx and Trachea Mouth Pharynx (Throat) 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

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

  20. 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

  21. 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

  23. 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

  24. 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

  25. 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.

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

  27. TYPE s OF BREATHING

  28. CHEST BREATHING (among bone rib muscular) INSPIRATION: The ribs to be sure that the muscle among bone chest cavity, chest cavity becomes larger for that cause the pressure in the chest cavity becomes smaller in comparison to the pressure external so that oxygen-rich air outside the entrance. EXPIRATION : phase relaxation or muscle some of the ribs return to the opening position is followed by a decline in the ribs so that the chest cavity becomes smaller. Because of this, the pressure inside the chest cavity will become larger than the external pressure, so air in the chest cavity is rich in carbon dioxide out.

  29. ABDOMINAL BREATHING (includes the diaphragm muscle) INSPIRATION : This phase of the diaphragm muscle contraction and the position become horizontal, chest cavity becomes larger, for that causes the pressure in the chest cavity becomes smaller in comparison to the pressure outside so that oxygen-rich air outside the entrance. Expiratory : This phase is the phase diaphragm muscle relaxation or return to its original position that utilized by a decline in the ribs so that the chest cavity becomes smaller. As a result, the pressure inside the chest cavity becomes larger than outside pressure, so air in the chest cavity is rich in carbon dioxide out.
