1. From the atmosphere, what structures does air pass through during ven- tilation?
ANS Starts in atmosphere, then nose, nasopharyngeal space/orophargyneal space (if mouth
breather), then pharynx, larynx, trachea, bronchi, bronchioles, alveoli
2. What is the purpose of the nasal passages and nasopharynx?
ANS To warm/hu- midify air as it passes through
3. What is the difference between respiration and ventilation?
ANS Respiration refers to the exchange of gases in the alveoli, ventilation refers to the
movement
of air into the lungs. Respiration is needed to provide O2 to cells and remove waste products. Also
regulates pH of blood.
4. What are the structures of the upper airway?
ANS nose, mouth, tongue, jaw, pharynx and larynx
5. What structure is considered a landmark that divides the upper airway from lower?
ANS The larynx, anything above is upper. The larynx and below are lower.

6. What are the structures of the lower airways?
ANS larynx (includes adam's ap- ple/thyroid cartilage, cricothyroid membrane, cricoid
cartilage), trachea, bronchi, bronchioles, alveoli
7. Describe the anatomy of the larynx.
ANS From superior to inferior.Thyroid cartilage, cricothyroid membrane, and cricoid
membrane. The thyroid cartilage and cricoid cartilage are anterior to the larynx, and the
cricothyroid membrane is posterior to both structures.
8. True or false
the lungs are completely equal in the midsaggital plane.
ANS False, right lungs has 3 lobes, left lung only has 2 lobes. Together they have 5 total. Also,
the right bronchi is inferior to the left bronchi.
9. What are the structures of the lungs in order of ventilation?
ANS bronchioles, and alveoli
10. True or false
ANS the lungs use muscles found in the lateral lobes to expand and contract?
ANS False
the lungs are hollow organs and contain no muscles. When the diaphragm contracts it expands
the thoracic cavity. The pleural space has a negative pressure and the lungs expand.This results

in a slightly negative pressure (compared to the atmosphere) and air rushes in.
11. True or false
Air rushes into the lungs because of negative pressure.
ANS True, when the lungs expand, they are creating a vacuum because they are expanding the
volume of the container. This increase in volume causes influx of air into the container until the
pressure is equalized with the atmosphere.
12. True or false The parietal pleura lines the lungs and the visceral pleura lines the
lungs. The space between is called the anterior pleura.
ANS False
the visceral pleura lines the lungs, the parietal pleura lines the body cavity and the

pleural space is the space in between both where body fluid allows for both to smoothly glide.
13. What muscles are involved in inhalation?
ANS The diaphragm, cervical muscles (neck), intercostals, abdominal muscles, and pectoral
muscles.
14. What muscles are involved in expiration?
ANS none, expiration (if done passively) is achieved by the relaxation of the diaphragm.
15. What is the primary driver of respiration? (Why would we increase/de- crease RR?)
ANS The CSF in the brain has chemoreceptors sensitive to CO2. When there is too much CO2.
The pH changes. These sensors feed back to the medulla oblongata, which stimulates the phrenic
nerve which innervates the diaphragm.They cause an increase in activity of the diaphragm.This
increases the RR which causes us to increase tidal volume. This means more CO2 is exhaled. And
brings our pH back to normal.
We also have the less sensitive hypoxic drive
16. What is hypoxic drive?
ANS Backup system to control respiration. Chemoreceptors in brain, aorta, and carotid arteries.
But they are "satisfied" by a small amount of O2, which means it is not as sensitive as pH control
of CO2
