What is the purpose of the nasal passages and
nasopharynx? - correct answers✅To warm/humidify air as
it passes through
What is the difference between respiration and
ventilation? - correct answers✅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.
What are the structures of the upper airway? - correct
answers✅nose, mouth, tongue, jaw, pharynx and larynx
What structure is considered a landmark that divides the
upper airway from lower? - correct answers✅The larynx,
anything above is upper. The larynx and below are lower.
What are the structures of the lower airways? - correct
answers✅larynx (includes adam's apple/thyroid cartilage,

cricothyroid membrane, cricoid cartilage), trachea,
bronchi, bronchioles, alveoli
Describe the anatomy of the larynx. - correct
answers✅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.
True or false: the lungs are completely equal in the
midsaggital plane. - correct answers✅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.
What are the structures of the lungs in order of
ventilation? - correct answers✅bronchioles, and alveoli
True or false: the lungs use muscles found in the lateral
lobes to expand and contract? - correct answers✅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.
,FISDAP Airway Exam Question And
Answers 2024
True or false: Air rushes into the lungs because of
negative pressure. - correct answers✅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.
True or false: The parietal pleura lines the lungs and the
visceral pleura lines the lungs. The space between is
called the anterior pleura. - correct answers✅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.
What muscles are involved in inhalation? - correct
answers✅The diaphragm, cervical muscles (neck),
intercostals, abdominal muscles, and pectoral muscles.
What muscles are involved in expiration? - correct
answers✅none, expiration (if done passively) is achieved
by the relaxation of the diaphragm.
What is the primary driver of respiration? (Why would we
increase/decrease RR?) - correct answers✅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
What is hypoxic drive? - correct answers✅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
What two areas of the brain are involved in respiration? -
correct answers✅medulla-controls rhythm, initiates
inspiration, sets base pattern for respirations, and
stimulates diaphragm to contract.
pons-changes depth of inspiration, expiration or both.
