Health Ch 13 Respiratory System

  1. Functions of respiratory system
    • bring O2 to body by breathing process:
    • inspiration
    • expiration
  2. apena
    cessation of breathing
  3. bradypena
    abnormally slow rate of breathing
  4. chronic
    persisting over a long period of time
  5. cilia
    hairlike projections from the surface of a cell
  6. dysphagia
    difficulty swallowing
  7. dyspnea
    difficult or labored breathing
  8. eupnea
    easy or normal breathing
  9. expiration
    act of breathing out, exhalation
  10. inspiration
    act of drawing air into lung, inhalation
  11. mediastinum
    thoracic space between lungs
  12. phlegm
    thick mucus secreted by tissues in respiratory passages & usually discharged through mouth (hoogie)
  13. respiration
    • exchange of O2 & CO2 between atmosphere & cells
    • aka ventilation
  14. tachypnea
    excessively fast respiration
  15. external respiration
    • aka ventilation
    • brings O2 to lungs
  16. internal respiration
    exchanges O2 & CO2 between blood & body cells
  17. cellular respiration
    changes acid produced during metabolism into harmless chemicals in the cells
  18. inhalation process
    • air enters through nose/mouth
    • air funneled through throat & into trachea
    • trachea branches into 2 tubes called bronchi
    • each bronchus enters 1 of lungs & branches into smaller tubes called bronchioles
    • bronchioles have small sacs @ ends called alveoli
    • capillaries in walls of alveoli exchange O2 & CO2 by process of diffusion
  19. rate
    • normal rate of respiration
    • varies w/ age, gender, posture, excersize, temperature, etc
  20. normal breath rates
    • kids: 20x's a min
    • adults: 16-20x's a min
    • elderly: often less than 16x's a min
  21. character
    • regular rhythm occuring @ regular intervals
    • apena = no respiration
    • deep or shallow
    • dry or wet
  22. luna volume
    • measurement of lung capacity
    • depends on age & physical condition
  23. tidal volume
    amount of air normally exchanged
  24. inspiratory reserve
    additional amount of air that can be inhaled
  25. expiratory reserve
    additional amt of air that can be exhaled
  26. blood gases
    measure how much O2 & CO2 are in blood, blood's pH, & etc gases
  27. bronchitis
    infection of the bronchi
  28. carbon monoxide poisoning
    occurs from breathing carbon monoxide
  29. chronic obstructive pulmonary disease
    group of chronic respiratory disorders including asthma, chronic bronchitis, & pulmonary emphysema
  30. cold
    respiratory infection
  31. cystic fibrosis
    genetic disorder of exocrine glands
  32. emphysema
    alveoli lose elasticity & become dialited & don't exchange gases well
  33. hantavirus
    respiratory condition spread by breathing contaminated urine/saliva of infected rodents such as deer, mice, & chipmunks
  34. hay fever
    respiratory inflam. caused by allergens such as plants, dust, & food
  35. lung cancer
    directly linked to smoking & smoke products
  36. pleural effusion
    air/fluid enters pleural capacity
  37. pleurisy
    inflam. of membranes in lungs
  38. pneumonia
    inflam. of lungs, buildup of excessive moisture impairs breathing
  39. pneumoconiosis
    inflam. in lungs caused by inhlaed irritants
  40. respiratory acidosis
    buildup of CO2 in blood, causing lowered blood pH
  41. respiratory alkalosis
    deficiency of CO2 in blood
  42. respiratory distress syndrome
    alveoli don't inflate properly
  43. sinusitis
    inflam. of 1+ paranasal sinuses
  44. sudden infant death syndrome (SIDS)
    respiratory disorder of newborns
  45. tuberculosis
    caused by bacteria difficult to destroy & can be transmitted through air
  46. upper respiratory infection
    caused by virus/bacteria in nose, pharynx, or larynx
