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 structure is The larynx, anything above is upper. The larynx and

divides the upper airway
from lower?
larynx (includes adam's apple/thyroid cartilage,
What are the structures of
cricothyroid membrane, cricoid cartilage), trachea,

bronchi, bronchioles, alveoli
From superior to inferior. Thyroid cartilage, cricothyroid
Describe the anatomy of membrane, and cricoid membrane. The thyroid cartilage

cricothyroid membrane is posterior to both structures.
True or false: the lungs are False, right lungs has 3 lobes, left lung only has 2 lobes.

midsaggital plane. inferior to the left bronchi.
What are the structures of bronchioles, and alveoli
the lungs in order of
ventilation?
, False: the lungs are hollow organs and contain no
True or false: the lungs use muscles. When the diaphragm contracts it expands the
muscles found in the lateral thoracic cavity. The pleural space has a negative
lobes to expand and pressure and the lungs expand. This results in a slightly
contract? negative pressure (compared to the atmosphere) and air
rushes in.
True, when the lungs expand, they are creating a vacuum
True or false: Air rushes into because they are expanding the volume of the container.

atmosphere.
True or false: The parietal False: the visceral pleura lines the lungs, the parietal
pleura lines the lungs and pleura lines the body cavity and the pleural space is the
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 The diaphragm, cervical muscles (neck), intercostals,
in inhalation? abdominal muscles, and pectoral muscles.
What muscles are involved none, expiration (if done passively) is achieved by the
in expiration? relaxation of the diaphragm.
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
What is the primary driver

increase tidal volume. This means more CO2 is exhaled.
And brings our pH back to normal.
We also have the less sensitive hypoxic drive
Backup system to control respiration. Chemoreceptors in
brain, aorta, and carotid arteries. But they are "satisfied"
What is hypoxic drive?
by a small amount of O2, which means it is not as
sensitive as pH control of CO2
