2 Respiratory System

3 The respirator y system is used to exchang e gases between the human body and its environm ent. Internally, it helps exchange oxygen with the carbon dioxide in the blood.

4 The major organ involved in respiratio n 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 Air (oxygen) is breathed in through the nose. Nose hairs help keep out unwanted particles. Respiratory System

20 Unwanted Particles Oxygen Respiratory System

21 Unwanted Particles Oxygen Respiratory System

22 Unwanted Particles Oxygen Respiratory System

23 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

34 Pharynx Larynx The pharynx runs from behind the nasal passages and mouth to just above the 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 Pharynx Larynx After the oxygen passes through the pharynx, it enters the larynx. The larynx is also where the voice box is located. Respiratory System

37 The larynx is followed by the trachea. 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

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

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

47 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

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

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

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

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

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

53 Bronchi and Bronchioles The bronchial tubes branch into bronchioles. Respiratory System

54 Bronchi and Bronchioles Bronchioles have thin walls without much cartilage bands. Respiratory System
