What is the function of the Epiglottis Cartilage
To close the glottis while swallowing
Which cartilage in the larynx has a complete ring
Which cartilage forms the Adams Apple
Name two functions of the nasal mucosa
Warm the ear
Moisten the ear
Trace a molecule of Oxygen from the external nares to the pulmonary capillaries of the lungs
Define pulmonary ventilation
• Mechanical flow of air into (inhalation) and out of (exhalation) of the lungs due to chest and lung volume changes which cause pressure changes.
• The flow of gases equalizes the pressure.
• The constant alteration between inspiration
Define external respiration
• Exchange of gases between the air spaces in the lungs and the blood in the pulmonary capillaries
• The blood gains O2 and loses CO2
5. The rings of the trachea are incomplete posteriorly, what is the significance of that?
• To allow the esophagus to expand while swallowing
9. Define internal respiration
• Exchange of gases between blood in systemic capillaries and tissue cells
• The blood loses O2 and gains CO2.
10. Define cellular respiration
• Using oxygen in the cellular processes to produce ATP
11. Define dead space.
• NO gas exchange between the air spaces in the lungs and the blood in the pulmonary capillaries
12. Why oxygen moves from the alveoli into the pulmonary capillaries?
• High concentration or pressure in the lung to low concentration or pressure in the capillaries
13. The upper respiratory system structures are.
• Nose, nasal cavity, paranasal sinuses, and pharynx
14. The lower respiratory system structures are
• larynx, trachea, bronchi, bronchioles, and alveoli
15. List the paranasal sinuses and their functions.
• Frontal, sphenoid, ethmoid, and maxillary
• Frontal, maxillary, and anterior and middle ethmoid drain into middle meatus
• Sphenoid and posterior ethmoid drain into superior meatus
• Make the skull lighter
• Produce mucus that moisten and clean the air
• Resonating chambers for sound
16. The hard palate separates the
Nasal __ cavity from the ____Oral ___ cavity.
17. What is the function of the soft palate?
• To close the internal nareses and stop the food from entering the nasal cavity
19. The Pharynx is commonly called
• The throat
20. Which primary bronchus is wider, shorter, and more vertical; the left or the right?
• The right.
21. What type of epithelium you will find in the trachea.
22. What is the function of the cilia in the trachea?
• To move the mucus towards the oral cavity
23. The left primary bronchus divides into how many secondary bronchi?
• Two secondary bronchi.
24. The right primary bronchus divides into how many secondary
• Three secondary bronchi.
25. List the three parts of the respiratory zone.
• Respiratory bronchioles, alveolar ducts, alveolar sac, alveoli
26. The conducting zone includes
• Nose, pharynx, larynx, trachea, bronchi, bronchioles, and terminal bronchioles
27. List two functions of respiratory system
• Gas exchange
• Acid base balance
28. Which tonsil located in the Nasopharynx
• One Pharyngeal or adenoid
29. Nasopharynx lies posterior to what
• Nasal cavity
30. What is the function of the Nasopharynx
• Passageway for air
31. The Oropharynx lies posterior to what
• Oral cavity
32. What is the function of Oropharynx?
• Passageway for air and food
33. Name the tonsils located in the Oropharynx
• Two Palatine tonsils
34. The vocal cords are attached posterolaterlly to which cartilage
35. Name the two layers that enclose the lungs
• Parietal and visceral layers
36. What are the layers of the respiratory membrane
• Alveolar epithelium
• Epithelial basement membrane underlying alveolar wall
• Capillary basement membrane that is often fused to the epithelial basement membrane
• Endothelial cells of the capillary
