QUESTIONS WITH DETAILED VERIFIED ANSWERS (100%
CORRECT ANSWERS) ALREADY GRADED A+
From the atmosphere, what structures does air pass
through during ventilation? - CORRECT ANSWER
>>>>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? - CORRECT ANSWER >>>>To
warm/humidify air as it passes through

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 ANSWER >>>>nose, mouth, tongue, jaw,
pharynx and larynx
What structure is considered a landmark that
divides the upper airway from lower? - CORRECT
ANSWER >>>>The larynx, anything above is upper.
The larynx and below are lower.
What are the structures of the lower airways? -
CORRECT ANSWER >>>>larynx (includes adam's
apple/thyroid cartilage, cricothyroid membrane,
cricoid cartilage), trachea, bronchi, bronchioles,
alveoli
Describe the anatomy of the larynx. - CORRECT
ANSWER >>>>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 ANSWER >>>>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 ANSWER >>>>bronchioles,
and alveoli
True or false: the lungs use muscles found in the
lateral lobes to expand and contract? - CORRECT
ANSWER >>>>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. - CORRECT ANSWER >>>>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
ANSWER >>>>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
ANSWER >>>>The diaphragm, cervical muscles
(neck), intercostals, abdominal muscles, and
pectoral muscles.
What muscles are involved in expiration? -
CORRECT ANSWER >>>>none, expiration (if done
