  2. The Respiratory System Respiratory System

  3. The respiratory system is used to exchange gases between the human body and its environment. Internally, it helps exchange oxygen with the carbondioxide in the blood. Respiratory System

  4. The major organ involved in respiration is the lungs. \Every animal, with the exception of fish, have two lungs. Respiratory System

  18. How Does The Respiratory System Work? Respiratory System

  19. The Nose Air (oxygen) is breathed in through the nose. Nose hairs help keep out unwanted particles. Respiratory System

  20. Unwanted Particles Oxygen Respiratory System

  24. The walls inside the nose are lined with membranes containing two types of cells. Some are ciliated while others produce mucous. Respiratory System

  25. The walls inside the nose are lined with membranes containing two types of cells. Some are ciliated while others produce mucous. Respiratory System

  26. Together , the mucous and cilia prevent most dust and other particles from traveling any farther. Respiratory System

  27. Together , the mucous and cilia prevent most dust and other particles from traveling any farther. Respiratory System

  28. The mucous is wet and sticky which helps it moisten the air. Respiratory System

  29. The mucous is wet and sticky which helps it moisten the air. Respiratory System

  30. As the air travels through the nasal passages, it is warmed by the capillaries running nearby. Respiratory System

  31. As the air travels through the nasal passages, it is warmed by the capillaries running nearby. Respiratory System

  32. Thus, the nose helps clean, moisten, and warm the air in the beginning of the process. Respiratory System

  33. Pharynx Larynx Respiratory System

  34. The pharynx runs from behind the nasal passages and mouth to just above the larynx Pharynx Larynx Respiratory System

  35. Pharynx Larynx The pharynx is part of both the respiratory and the digestive systems. It is the throat. Respiratory System

  36. After the oxygen passes through the pharynx, it enters the larynx. The larynx is also wherethe voice box is located. Pharynx Larynx Respiratory System

  37. Trachea The larynx is followed by the trachea. Respiratory System

  38. The trachea is about 12 centimeters long and it is lined by bands of cartilage for support. Respiratory System

  39. The trachea is about 12 centimeters long and it is lined by bands of cartilage for support. Respiratory System

  40. Respiratory System

  41. Ciliated goblet cells The trachea, like the nasal passages, have cilia lined mucous membranes. Respiratory System

  42. Ciliated goblet cells The cilia help to remove harmful particles from the trachea. Respiratory System

  43. Ciliated goblet cells If food unintentionally falls into the trachea, the cilia help bring it back up to the pharynx. Respiratory System

  44. Bronchi and Bronchioles Respiratory System

  45. Bronchi and Bronchioles The bronchi are two cartilage banded tubes that branch out from the trachea. Each bronchi enters one of the lungs. Respiratory System

  46. Bronchi and Bronchioles The bronchi are two cartilage banded tubes that branch out from the trachea. Each bronchi enters one of the lungs. Respiratory System

  47. BronchiandBronchioles The bronchi are two cartilage banded tubes that branch out from the trachea. Each bronchi enters one of the lungs. Respiratory System

  48. Bronchiand Bronchioles The two bronchi, themselves divide into even smaller sets of tubes called the bronchial tubes. Respiratory System

  49. Bronchiand Bronchioles The two bronchi, themselves divide into even smaller sets of tubes called the bronchial tubes. Respiratory System

  50. Bronchiand Bronchioles The bronchial tubes lose cartilage and the walls become thinner as the tubes branch. Respiratory System
