FISDAP-AIRWAY
Upper Airway - *answers * Consists of all structures above the level of the vocal cords. The
nose, mouth, jaw, oral cavity, and pharynx.
Lower Airway - *answers * Function is to exchange oxygen and carbon dioxide. Starts at the
larynx. Spans from the glottis to the pulmonary capillary membrane.
Turbinates - *answers * Increase the surface area of the nasal mucosa, thereby improving the
processes of warming, filtering, and humidification of inhaled air.
Hyoid Bone - *answers * Small, horseshoe-shaped bone that attaches to the tongue.
Thyroid Cartilage - *answers * Adam's apple. Directly anterior to the glottic opening.
Cricoid Cartilage - *answers * AKA Cricoid Ring, forms the lowest portion of the larynx, and the
first ring of the trachea.
Cricothyroid Membrane - *answers * Site for emergency surgical and nonsurgical access to the
airway. Between the thyroid and cricoid cartilage.
Vellecula - *answers * Anatomic space or "pocket" located between the base of the tongue and
the epiglottis. Where the MAC blade goes.
Laryngospasm - *answers * When the airway is stimulated (such as during aspiration of foreign
material or submersion incident), defensive reflexes cause a spasmodic closure of the vocal
cords, which seals off the airway.
Trachea - *answers * AKA Windpipe, is the conduit for air entry into the lungs. Approx 10-12 cm
long, & consists of C-shaped cartilaginous rings. Begins immediately below the cricoid cartilage.
Divides into the right and left mainstem bronchi at the level of the Carina.

Mediastinum - *answers * The space between the lungs that contains, in addition to the
trachea, the heart, great vessels, and a portion of the esophagus. The main thing to know- the
heart is housed there.
Carina - *answers * Where the right and left mainstem bronchi branch off.
Goblet Cells - *answers * Mucous-producing cells, that are lined in the trachea and bronchi.
They trap small particles and other potential contaminants.
Beta-2 Adrenergic Receptors - *answers * Stimulate bronchodilation.
# of Lobes in each Lung - *answers * Right lung- 3, Left lung- 2.
Visceral pleura - *answers * Thin, slippery, outer membrane covering the lungs.
Parietal Pluera - *answers * Lines the inside of the thoracic cavity.
Bronchioles - *answers * Made of smooth muscle & lined with beta-2 receptors, which can
dilate and constrict based on stimuli.
Alveoli - *answers * Balloon-like clusters of single-layer air sacs, and serve as the functional site
for the exchange of oxygen and CO2. This exchange occurs by simple diffusion over the
pulmonary capillaries.
Ventilation - *answers * Process of moving air in and out of the lungs. Consists of two phases-
inhalation and exhalation.
