3. Muhammad Asif Pak 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. Muhammad Asif Pak 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 (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. Muhammad Asif Pak Here We Go!!! 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

6. Here is a overview picture of the Respiratory System . Just go to the next slide to see it. Muhammad Asif Pak

8. The Respiratory System Muhammad Asif Pak 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. Muhammad Asif Pak

10. Muhammad Asif Pak 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 .

11. Muhammad Asif Pak Nasal Cavity Nostril Oral Cavity Pharynx Here is a picture of your nasal and oral cavity .

12. Muhammad Asif Pak We are here. 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

13. Muhammad Asif Pak 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 .

14. Muhammad Asif Pak 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

15. Muhammad Asif Pak We are here. 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

16. Your trachea (windpipe) splits up into two bronchi tubes . These two tubes keep splitting up and form your bronchiole . Muhammad Asif Pak

17. Muhammad Asif Pak 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…

18. Muhammad Asif Pak Trachea Bronchi Tubes Bronchiole Alveoli

19. Muhammad Asif Pak We are here. 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

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

21. Muhammad Asif Pak 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.

22. Muhammad Asif Pak 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

23. Muhammad Asif Pak We are here. 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

24. Muhammad Asif Pak Bronchiole Respiratory Bronchiole Alveolar Duct Alveolar Sac Capillaries Alveolus

25. Muhammad Asif Pak Lets take a closer look shall we.

26. Muhammad Asif Pak Red blood cell carrying Carbon dioxide Chemical change is taking place in cell Red blood cell carrying oxygen Alveolus Contiguous Basal Laminae (Membrane) Capillary

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

28. Muhammad Asif Pak

29. Muhammad Asif Pak Now we will look at the Diaphragm . You might be wondering, what does the Diaphragm do? The Diaphragm is an important factor in breathing.

30. Muhammad Asif Pak

31. Here is an experiment that you can try. Muhammad Asif Pak

32. Muhammad Asif Pak 1 st you need a bottle that you can sacrifice to cut up. 2 nd you cut the bottom of the bottle and put a big balloon on the bottom. 3 rd 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. 4 th make sure the thing is airtight.

33. Muhammad Asif Pak CO 2 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 stem Air 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

40. __ __________ _____ _____ ______ ___ __ ____ Muhammad Asif Pak Circulatory System Created by

42. Muhammad Asif Pak This organ is what pumps oxygen rich blood, nutrients, hormones, and the other things your body needs to maintain your health, to your organs and tissues. The pulmonary veins you see on the right side of the diagram come from your lungs, where the blood cells collect oxygen. It’s then pumped out to the rest of the body through the Aorta (Top). All of the blue sections show blood cells carrying waste, (C0 2 ) moving back to the lungs (where the C0 2 will be replaced by oxygen) through the Pulmonary Artery (Top, blue) Pulmonary Veins Pulmonary Artery (Inferior Vena Cava) From the Body (Aortic Artery) To the body Whenever the blood is pumped from one section of the heart another a valve closes behind it preventing the blood from moving backwards. By The Way… Valves: ( tricuspid valve semilunar (pulmonary) valve, bicuspid (mitral) valve, and the semilunar (aortic) valve (Superior Vena Cava) From the Body

45. A red blood cell then travels from the heart through arteries that eventually branch into the body’s vast system of capillaries (microscopic blood vessels which connect arteries and veins), they eventually lead to… Pulmonary Vein Aorta Brachial Artery Renal Artery Redial Artery Ulnar Artery Iliac Artery Muhammad Asif Pak

46. When the itty bitty teeny tiny red blood cells pass the desired tissue they………………………………. TRANSACT The oxygen the blood cells are carrying is given to the body’s tissue. And the CO 2 (waste) from the tissue is given to the same blood cell to be exhaled. Tissue Tissue Technically the Hemoglobin in the blood (a substance full of iron) attracts oxygen from the lungs. The red blood cell then carries it to the desired tissue. Because this tissue has a high CO 2 count the hemoglobin lets go of its oxygen and collects the carbon dioxide. You see the hemoglobin has an affinity for whichever gas has a greater count. Because the tissue has a large amount of built up waste (CO 2 ) the hemoglobin attracts it and then replaces it with oxygen, and vise versa in the lungs. How It Works… Oxy-Rich Blood Cell Oxy-Poor Blood Cell Now lets travel to the legs!!! Muhammad Asif Pak

48. The oxygen and CO 2 are exchanged…in the cells Oxygen Rich Oxygen Rich Oxygen Poor Oxygen Poor Tissue Don’t forget that the Hemoglobin in the blood cells let go of the cell’s oxygen because of the large CO 2 (waste) count in the tissue. Muhammad Asif Pak Now lets go back to the heart!!!

50. Muhammad Asif Pak As you have learned (Hopefully ) the Circulatory System is one of the most important systems in the human body… It is the only reason you’re still alive today… and you can attribute the cooling down, feeding of and protection of your body to it. So the next time you bust open your leg skateboarding you can thank your Circulatory System for patching you up.

52. So Take a Deep Breath and Go Home Muhammad Asif Pak The End!
