  1. Respiratory System

  2. Healthy Lung Vs. Smokers Lung • http://www.youtube.com/watch?v=yskYG-EVlBY • https://www.youtube.com/watch?v=yIURbmJZxIg

  3. Upper Respiratory system • Internal Nares- Allows air to enter the nose and pass through into the nasal cavity

  4. Upper Respiratory System • Nasopharynx- upper most part of the pharynx; passage way for air

  5. Upper Respiratory System • Eustachian Tubes- links pharynx to middle ear; pressure equalization, mucus drainage

  6. Upper respiratory system • Hard Palate- roof of the mouth; speech production

  7. Upper Respiratory System • Soft Palate- does not contain bone • located at the back of the mouth • speech production, separates nasal cavity and oral cavity when swallowing

  8. Upper Respiratory System • Palatine Tonsil- left and right side of the back of the throat; provides defense against pathogens

  9. Upper respiratory system • Oropharynx- below soft palate and below epiglottis; passage way for air and food

  10. Upper Respiratory system • Epiglottis- flap structure that allows air to enter the trachea

  11. Upper Respiratory System • Glottis- slit of the epiglottis, space between vocal chords; adds buzzing quality to speech Glottis

  12. Upper respiratory system • Vocal Folds • Production of sounds used for speech • Regulate flow of air into lungs

  13. Upper respiratory system • Laryngopharynx- lower part of pharynx; passage of air and food

  14. Upper respiratory system • Trachea- ciliated mucus membrane; filters air and traps particles

  15. Upper respiratory system • Nasal Conchae • Increase Surface area for filtration of air • Warms and moistens air

  16. Upper respiratory system • Nasal Vestibule • Beginning of nasal passage • Hair helps to capture large particles

  17. Upper respiratory system • Oral Cavity- mouth • Lining of the mouth and saliva glands aid provide lubrication • Aids in speech, swallowing, and digestion of food

  18. Upper respiratory system • Tongue- aids in speech and in swallowing to cover up epiglottis when you swallow

  19. Upper respiratory system • Thyroid Cartilage- Adam’s Apple • Protection and support for the vocal folds

  20. Upper respiratory System • Cricoid Cartilage • Connection for ligaments, cartilage, and muscles • Facilitates opening and shutting of air passage • Production of sound

  21. Lower respiratory system • Larynx • Between the pharynx and trachea • Houses the vocal folds • A passageway for air moving in and out of the trachea

  22. Lower respiratory system • Parietal Pleura • Lines the inner wall of the chest • Covers the diaphragm • Lubrication- serous fluid

  23. Lower respiratory system • Visceral Pleura • Membrane on the lung • Easy movement of lungs within chest wall

  24. Lower respiratory system • Alveolar Sac • Cluster of alveoli located at the end of each alveolar duct • Contain alveoli

  25. Lower respiratory system • Alveolar Duct • Connects bronchioles to alveolar sacs

  26. Lower respiratory system • Alveolus • Site of gas exchange with blood • Secrete Surfactant

  27. Lower respiratory system • Diaphragm • Muscle that separates thoracic cavity from abdominal cavity • Performs an important function in respiration

  28. Lower respiratory system • Tracheal Cartilage • Shape and support trachea • Ring Shaped- 16 to 20

  29. Lower respiratory system • Apex of Lung • Rounded upper portion of the lung

  30. Lower respiratory system • Mediastinum • Divides thoracic cavity into two pleural cavities

  31. Lower respiratory system • Left Primary Bronchus • Main passageway into the lungs

  32. Lower respiratory system • Lower Terminal Bronchioles • End of the conduction zone • Transitions to the respiratory zone

  33. Lower respiratory system • Conduction Zone • Nose, pharynx, larynx, trachea, bronchi, bronchioles, and terminal bronchioles • Respiratory Zone • Site of gas exchange; CO2 and O2

  34. Lower respiratory system • Carina • Bottom of trachea; splits into primary bronchus • Mucus membrane is sensitive and triggers cough reflex

  35. Lower respiratory system • Secondary Bronchi (120) • Branches off of the primary bronchi • Tertiary Bronchi (121) • Branches off of the tertiary bronchi • Splits into bronchioles

  36. Respiratory System • _____________ provides an opening for air to enter and leave the nasal cavity. • List the three ways in which the upper respiratory system filters the air before it reaches the lungs. • Describe the function of the epiglottis. • The _____________ are the primary site for gas exchange. • Explain the difference between the conduction zone and the respiratory zone. • Describe the function of the diaphragm.
