Across
  1. 3. collective name for the multiple branches of the bronchi and bronchioles of the respiratory system
  2. 6. outermost layer of the pleura that connects to the thoracic wall, mediastinum, and diaphragm
  3. 8. small, grape-like sac that performs gas exchange in the lungs
  4. 9. opening between the vocal folds through which air passes when producing speech
  5. 12. portion of the larynx composed of a ring of cartilage with a wide posterior region and a thinner anterior region; attached to the esophagus
  6. 13. organ of the respiratory system that performs gas exchange
  7. 15. portion of the pharynx flanked by the nasopharynx, oral cavity, and laryngopharynx that is a passageway for both air and food
  8. 18. smooth muscle located in the fibroelastic membrane of the trachea
  9. 19. tube connected to the trachea that branches into many subsidiaries and provides a passageway for air to enter and leave the lungs
  10. 21. region where the two lamina of the thyroid cartilage join, forming a protrusion known as “Adam’s apple"
Down
  1. 1. portion of the pharynx flanked by the conchae and oropharynx that serves as an airway
  2. 2. artery that arises from the pulmonary trunk and carries deoxygenated, arterial blood to the alveoli
  3. 4. portion of the pharynx bordered by the oropharynx superiorly and esophagus and trachea inferiorly; serves as a route for both air and food
  4. 5. tube composed of cartilaginous rings and supporting tissue that connects the lung bronchi and the larynx; provides a route for air to enter and exit the lung
  5. 7. small tube that leads from the terminal bronchiole to the respiratory bronchiole and is the point of attachment for alveoli
  6. 8. cluster of alveoli
  7. 10. one of the pair of folded, white membranes that have a free inner edge that oscillates as air passes through to produce sound
  8. 11. eaf-shaped piece of elastic cartilage that is a portion of the larynx that swings to close the trachea during swallowing
  9. 14. innermost layer of the pleura that is superficial to the lungs and extends into the lung fissures
  10. 16. region of the conducting zone that forms a tube of skeletal muscle lined with respiratory epithelium; located between the nasal conchae and the esophagus and trachea
  11. 17. specific type of bronchiole that leads to alveolar sacs
  12. 20. cartilaginous structure that produces the voice, prevents food and beverages from entering the trachea, and regulates the volume of air that enters and leaves the lungs
