Medical Terminology Chapter 5

  1. The area in the lungs where carbon dioxide and oxygen are exchanged:
    during external respiration, or breathing, oxygen passes from the lungs to the blood in the capillaries

    carbon dioxide also passes from the capillaries back into the lungs to be expelled
  2. nasal septum:
    partition separating the right and left nasal cavities
  3. pharynx:
    (also called the throat)

    serves as a food and air passageway

    air enters from the nasal cavities and passes through the pharynx to the larynx

    food enters the pharynx from the mouth and passes into the esophagus
  4. adenoids:
    lymphoid tissue located behind the nasal cavity
  5. larynx:
    (also called the voice box)

    location of the vocal cords

    air enters from the pharynx
  6. nose:
    lined with numerous mucous membrane and fine hairsit

    acts as a filter to moisten and warm the entering air
  7. paranasl sinuses:
    air cavities withen the cranial bones that open into nasal cavities
  8. tonsils:
    lymphoid tissue located behind the nasal cavity
  9. epiglottis:
    flap of cartilage that automatically covers the opening of and keeps food from entering the larynx during swallowing
  10. trachea:
    (also called the windpipe)

    passageway for air to the bronchi
  11. bronchus (pl. bronchi):
    inferior to the trachea

    1 of 2 branches from the trachea that conducts air into the lungs, where it divides and subdivides

    the branchings resemble a tree; therefore, they are referred to as a bronchial tree
  12. bronchioles:
    smallest subdivision of the bronchial tree
  13. alveolus (pl. alveoli):
    air sacs at the end of the bronchioles

    it aids in the breathing process by contracting and pulling air in, then relaxing and pushing air out
