2024 Questions and Correct Answers

From the atmosphere, what structures does air pass through during
ventilation? -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? -
ANSWER-To warm/humidify air as it passes through
What is the difference between respiration and ventilation? -
ANSWER-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? -ANSWER-nose, mouth,
tongue, jaw, pharynx and larynx
What structure is considered a landmark that divides the upper airway
from lower? -ANSWER-The larynx, anything above is upper. The
larynx and below are lower.
What are the structures of the lower airways? -ANSWER-larynx
(includes adam's apple/thyroid cartilage, cricothyroid membrane,
cricoid cartilage), trachea, bronchi, bronchioles, alveoli
,Describe the anatomy of the larynx. -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.
-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? -
ANSWER-bronchioles, and alveoli
True or false: the lungs use muscles found in the lateral lobes to
expand and contract? -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. -
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. -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? -ANSWER-The diaphragm,
cervical muscles (neck), intercostals, abdominal muscles, and pectoral
muscles.
What muscles are involved in expiration? -ANSWER-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?) -ANSWER-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? -ANSWER-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? -ANSWER-
medulla-controls rhythm, initiates inspiration, sets base pattern for
respirations, and stimulates diaphragm to contract.
Pons-changes depth of inspiration, expiration or both.
True or false: arteries bring oxygenated blood to organs/capillaries -
ANSWER-True in most cases with one exception. Arteries (away)
