Respiratory system

  1. what are the funcitons of the respiratory system
    • provides an extensive area for gas exchange between air from environment and circulating blood
    • incoming air is filtered of dirt and pathogens by mucous and cilia, warmed by superficial blood vessels, mositened by mucous while being sent to gash exchange
    • production of sounds
    • provides olfactory sensation
    • assists in regulating body fluid pH
  2. What is the pathway of air through the respiratory system

  10. how does the larynx produce sound waves
    air passing through the glottis vibrates the vocal chords

  19. after air leaves the pharynx what does it pass through
  20. what organ of the respiratory system allows air to move from the larynx to the bronchi
  21. what part of the trachea stiffen the walls to protect airway and prevent collapse and overexpansion
    tracheal cartilage rings
  22. what don't the c-shaped cartilage rings in the trachea protect posteriorly
    to allow a large bolus down the adjacent esophagus
  23. what type of WBC in the respiratory system is located in the alveolar epithelium
    alveolar macrophages
  24. what type of WBC phagocytize unwanted pathogens and debris
    alveolar macrophages
  25. what part of the respiratory system separates the air in the alveoli from the blood in surounding capillaries
    respiratory membrane
  26. what part of the respiratory system is a fluid that reduces surface tension between pleural membranes that prevents alveoli/lungs from collapsing
  27. what 3 parts of the respiratory system contain surfactant
    • alveolar membrane
    • capillary membrane
    • intersitital fluid
  28. what function of the respiratory system includes all processes involved in the gas exchange of oxygen, co2 between the ECF and environment
    external respiration
  29. what are the 4 parts of external respiration
    • pulmonary ventilation
    • gas diffusion across respiratory membrane between alveolar air sacs and capillaries
    • storage and transport oxygen and co2 between alveolar capillaries and capillary beds in other tissues
    • exchange of o2 and co2 between blod and ECF
  30. what is the movment of air into the lungs called
  31. what is the movement of air out of the lungs
  32. what organ of the respiratory system form the floor of the thoracic cavity
  33. what is the shape of the diaphragm when it is relaxed
    dome projecting upward into the thoracic cavity
  34. what is the shape of the diaphragm when its contracted
    tenses and moves down causing an increase in the thoracic cavity volume
  35. when does the thoracic cavity become increased
    when the ribs and vertebrae are moved up, inhaling
  36. when are pressure inside and outside the thoracic cavity equal
    at the start of a breath
  37. when does the thoracic cavity pressue decrease
    when it enlarges from diaphragm and intercoastal contracitons
  38. what focres air into the lungs
    decreased pressure in the thoracic cavity
  39. when does the thoracic cavity decrease in size
    relaxation of diaphragm and intercostals
  40. when does thoracic cavity pressure increase
    when thoracic cavity decreases
  41. what forces air out of the lungs
    increased pressure int he thoracic cavity
  42. what is one inhalation and one exhalation called
    respiratory cycle
  43. what respiratory disorder is an acute and characterized by sensitive, irritable airways causing a decrease in V.C. and ERV
  44. what respiratory disorder is a collapsed lung
  45. what respiratory disorder is respiration cessation
  46. what respiratory disorder is labored or difficult breathing
  47. what respiratory disorder is a decrease in the size of the respiratory airways
  48. what respiratory disorder is the enlargement of the respiratory airways
  49. what is a small fiber optic cable insereted down the respiratory tract that performs bronchioscopy called
  50. what is the application of cycles of compression to the rib cage and mouth to mouth breathing to maintain circulatory and respiratory function called
  51. what respiratory disorder is the chronic bronchitis and chronic airway obstruciton
    chronic obstructuve pulmonary disease (COPD)
  52. what respirartory disorder is caused by a drop in atmospheric pressure and results in the formation of nitrogen gas bubbles in body fluids, tissues and organs
