Chapter 9: Respiratory System; Anatomical Terms

  1. nose
    structure that warms, moistens, and filters air as it enters the respiratory tract and that houses the olfactory receptors for the sense of smell
  2. sinuses
    air-filled spaces in the skull that open into the nasal cavity
  3. palate
    partition between the oral and nasal cavities; divided into the hard and soft palate
  4. pharynx
    throat; passageway for food to the esophagus and air to the larynx
  5. nasopharynx
    part of the pharynx directly behind the nasal passages
  6. oropharynx
    central portion of the pharynx between the roof of the mouth and the upper edge of the epiglottis
  7. laryngopharynx
    lower part of the pharynx just below the oropharynx opening into the larynx and the esophagus
  8. tonsils
    oval lymphatic tissues on each side of the pharynx that filter air to protect the body from bacterial invasion - also called palatine tonsils
  9. adenoid
    lymphatic tissue on the back of the pharynx behind the nose - also called pharyngeal tonsil
  10. uvula
    small projection hanging from the back middle edge of the soft palate, named for its grape-like shape
  11. larynx
    voice box; passageway for air moving from pharynx to trachea; contains vocal cords
  12. glottis
    opening between the vocal cords in the larynx
  13. epiglottis
    lid-like structure that covers the larynx during swallowing to prevent food from entering the airway
  14. trachea
    windpipe; passageway from the larynx to the area of the carina where it splits into the right and left bronchus
  15. bronchial tree
    branched airways that lead from the trachea to the alveoli
  16. right and left bronchus
    two primary airways branching from the area of the carina into the lungs
  17. bronchioles
    progressively smaller tubular branches of the airways
  18. alveoli
    thin-walled microscopic air sacs that exchange gases
  19. lungs
    two spongy organs, located in the thoracic cavity enclosed by the diaphragm and rib cage, responsible for respiration
  20. lobes
    subdivisions of the lung, two on the left and three on the right
  21. pleura
    membranes enclosing the lung an lining the thoracic cavity
  22. pleural cavity
    potential space between the visceral and parietal layers of the pleura
  23. diaphragm
    muscular partiton that separates the thoracic cavity from the abdominal cavity and aids in respiration by moving up and down
  24. mediastinum
    partition that separates the thorax into two compartments and encloses the heart, esophagus, trachea, and thymus gland
  25. mucous membranes
    thin sheets of tissue that line the respiratory passages and secrete mucus, a viscid fluid
  26. cilia
    hair-like processes from the surface of epithelial cells, such as those of the bronchi, that provide upward movement of mucus cell secretions
  27. parenchyma
    functional tissues of any organ such as the tisses of the bronchioles, alveoli, ducts, and sacs that preform respiration
