From the atmosphere, what Starts in atmosphere, then nose, nasopharyngeal
structures does air pass space/orophargyneal space (if mouth breather), then
through during ventilation? pharynx, larynx, trachea, bronchi, bronchioles, alveoli
What is the purpose of the To warm/humidify air as it passes through
nasal passages and
nasopharynx?
What is the difference Respiration refers to the exchange of gases in the alveoli,
between respiration and ventilation refers to the movement of air into the lungs.
ventilation? Respiration is needed to provide O2 to cells and remove
waste products. Also regulates pH of blood.
What are the structures of nose, mouth, tongue, jaw, pharynx and larynx
the upper airway?
What structure is The larynx, anything above is upper. The larynx and below are
considered a landmark lower.
that divides the upper
airway from lower?
larynx (includes adam's apple/thyroid cartilage,
What are the structures of
cricothyroid membrane, cricoid cartilage), trachea,
the lower airways?
bronchi, bronchioles, alveoli
,Describe the anatomy of the From superior to inferior. Thyroid cartilage, cricothyroid
larynx. 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 False, right lungs has 3 lobes, left lung only has 2
completely equal in the lobes. Together they have 5 total. Also, the right
midsaggital plane. bronchi is inferior to the left bronchi.
What are the structures of bronchioles, and alveoli

ventilation?
True or false: the lungs use False: the lungs are hollow organs and contain no muscles.
muscles found in the When the diaphragm contracts it expands the thoracic
lateral lobes to expand and cavity. The pleural space has a negative pressure and the
contract? lungs expand. This results in a slightly negative pressure
(compared to the atmosphere) and air rushes in.
True or false: Air rushes into True, when the lungs expand, they are creating a vacuum

negative pressure. This increase in volume causes influx of air into the
container until the pressure is equalized with the
atmosphere.
True or false: The parietal False: the visceral pleura lines the lungs, the parietal
pleura lines the lungs and the pleura lines the body cavity and the pleural space is the
visceral pleura lines the space in between both where body fluid allows for both
lungs. The space between is to smoothly glide.
called the anterior pleura.
What muscles are involved in The diaphragm, cervical muscles (neck), intercostals, abdominal
inhalation? muscles, and pectoral muscles.
What muscles are involved in none, expiration (if done passively) is achieved by the relaxation of
expiration? the diaphragm.
, What is the primary driver of The CSF in the brain has chemoreceptors sensitive to CO2.
respiration? (Why would we When there is too much CO2. The pH changes. These
increase/decrease RR?)
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? 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 medulla-controls rhythm, initiates inspiration, sets base
brain are involved in pattern for respirations, and stimulates diaphragm to
respiration? contract. pons-changes depth of inspiration, expiration or
both.
True or false: arteries bring True in most cases with one exception. Arteries (away) bring
oxygenated blood to blood away from the heart. Usually this is oxygenated blood.
organs/capillaries But the pulmonary arteries bring oxygen poor blood away
from the heart, to the lungs to be oxygenated.
What is the tidal volume? amount of air moved in/out of lungs in single breath.
Usually 500 ml in adult
What is inspiratory reserve Deepest breath you can take after normal respiration
volume?
What is expiratory reserve maximum amount you can breathe out after normal breath.
volume/Vital Capacity?
Remaining gas in lungs after exhalation. This is to keep lungs
What is residual volume?
inflated
