815: Exam 5 Chapter 22 The Respiratory
System Questions and Answers (Expert
Solutions)
Q: What is the significance of the Respiratory and Cardiovascular systems?, 🗹🗹:
Deliver oxygen for metabolic processes that require ATP production and remove CO2
Q: Upper respiratory tract consists of, 🗹🗹: nose
nasal cavity
pharynx
Q: Lower respiratory tract consists of, 🗹🗹: larynx
trachea
bronchi
lungs
Q: Conducting zone, 🗹🗹: The respiratory passageways that carry or "conduct" the
air to sites of gas exchange.
Trachea
Bronchi
Bronchioles (non-respiratory section)
They also filter, humidify, and warm the air
, Page | 2
Q: Respiratory Zone, 🗹🗹: site of gas exchange
Respiratory bronchioles
alveolar ducts and sacs
*all microscopic structures
Q: What "generation" level does gas exchange occur?, 🗹🗹: below 15 (16 - 23)
generation: split in the respiratory tree
Q: What generation is the trachea?, 🗹🗹: Trachea 0
Bronchi 1-7 (1* carina - first split of the respiratory tree)
Bronchioles (non-respiratory) 8 - 15
Bronchioles (respiratory) 16 - 19
Alveolar ducts 20 - 23
Q: What is the external skeletal framework of the nose?, 🗹🗹: frontal and nasal bones
(form the root and bridge)
maxillary bones laterally
hyaline cartilage inferiorly
Q: 3 Functions of the nasal cavity:, 🗹🗹: 1. warm, cleanse, humidify inhaled air
2. contain olfactory receptors
3. modifies voice from resonating chambers
, Page | 3
Q: How does air travel through the nasal cavity:, 🗹🗹: 1. External nares (nostrils)
2. Vestibule (superior to nares) - contains vibrissae
3. through the nasal conchae (turbinates)
4. Internal nares (choanae or Posterior nasal aperture)
5. nasopharynx
Q: Function of the vibrissae?, 🗹🗹: Nose hairs - filter large particles like insects and
lint.
Q: What 3 structures make up the nasal septum?, 🗹🗹: perpendicular plate of
ethmoid
vomer
septal cartilage
Q: What is the roof and the floor of the nasal septum made of?, 🗹🗹: Roof:
ethmoid
sphenoid bones
Floor:
hard and soft palate (separates the nasal and oral cavity)
Q: T/F. Nasal deviations are nearly all traumatic in origin, affecting 75% of adults,
🗹🗹: True
Q: Septal perforation, 🗹🗹: The nasal septum (septal cartilage) may become
perforated due to substance (cocaine) abuse and nasal surgery
*Cocaine causes vasoconstriction of BV to septal cartilage
