FISDAP Airway Exam 113 COMPLETE QUESTIONS
WITH 100% RATED CORRECT ANSWERS 100%
VERIFIED GRADED A+
From the atmosphere, what structures does air pass through during ventilation? -
...(ANSWERS)....Starts in atmosphere, then nose, nasopharyngeal
space/orophargyneal space (if mouth breather), then pharynx, larynx, trachea,
bronchi, bronchioles, alveoli
What is the purpose of the nasal passages and nasopharynx? - ...(ANSWERS)....To
warm/humidify air as it passes through
What is the difference between respiration and ventilation? -
...(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? - ...(ANSWERS)....nose, mouth,
tongue, jaw, pharynx and larynx
What structure is considered a landmark that divides the upper airway from
lower? - ...(ANSWERS)....The larynx, anything above is upper. The larynx and
below are lower.
What are the structures of the lower airways? - ...(ANSWERS)....larynx (includes
adam's apple/thyroid cartilage, cricothyroid membrane, cricoid cartilage),
trachea, bronchi, bronchioles, alveoli
,Describe the anatomy of the larynx. - ...(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. -
...(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? -
...(ANSWERS)....bronchioles, and alveoli
True or false: the lungs use muscles found in the lateral lobes to expand and
contract? - ...(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.
True or false: Air rushes into the lungs because of negative pressure. -
...(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. - ...(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? - ...(ANSWERS)....The diaphragm,
cervical muscles (neck), intercostals, abdominal muscles, and pectoral muscles.
What muscles are involved in expiration? - ...(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?)
- ...(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? - ...(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
