ACC EMSP - 1356 Advanced Airway
Exam 1 Review Questions and Answers
Upper airway - Answer-Nasopharynx, nasal air passage, pharynx, mouth, oropharynx, epiglottis.
Lower airway - Answer-Trachea, alveoli, bronchioles, main bronchi, carina, diaphragm.
Upper airway functions - Answer-Air passage, warms, filters, humidifies, vocalization/resonance,
protection, smell/taste.
Lower airway functions - Answer-conduction of air, mucociliary clearance, production of pulmonary
surfactant
Nasopharynx Structures - Answer-Nasal Opening, Nasal Septum, Turbinates, Olfactory Membranes, and
Sinuses
Larynx Structures - Answer-Hyoid Bone, Cartilages (Epiglottis, Thyroid, Cricoid Ring), Cricothyroid
Membrane, Vocal Cords, and Vestibular Folds
Nasal Pharynx - Answer-A passageway that connects the mouth cavity and the nasal cavity.
,Oral Pharynx - Answer-back of soft palate to top of trachea (stratified squammous); shared space.
Nasal Opening - Answer-nose (hole)
Nasal Septum - Answer-Divides the nasal cavity into left and right portions
Turbinates (Conchae) - Answer-3 bony projects that protrude into the nasal cavities from the walls of
the interior portion of the nose; They increase the total surface are for filtering, heating, & humidifying
inspired air
Sinuses - Answer-Air spaces in the bones of the skull. Make us lighter
Olfactory membranes - Answer-specialized epithelial tissue inside the nasal cavity that is involved in
smell
Larynx and above - Answer-Upper airway
Trachea and below - Answer-Lower airway
Eustachian tube - Answer-Connects the middle ear to the throat. Equalizes pressure
Adenoids - Answer-Lymphoid tissue located behind the nasal cavity
Uvula - Answer-Dangles from the back of the roof of the mouth
Vallecula - Answer-Groove between tongue and epiglottis, used to lodge the blade of laryngoscope
, Epiglottis - Answer-A flab of tissue that prevents food from entering the trachea, or windpipe, during
swallowing
hyoid bone - Answer-A U-shaped bone located in the upper neck. It anchors the tongue and is
associated with swallowing.
Lingual tonsil - Answer-Lymphatic organ located at the base of the tongue, help resist infection.
laryngopharynx - Answer-Contains an anterior opening into the layrnx and a posterior opening into the
esophagus.
Esophagus - Answer-A muscular tube that connects the mouth to the stomach. You will NOT see vocal
cords in this.
Thyroid - Answer-Upper part - Endocrine gland that surrounds the trachea in the neck.
Cricoid - Answer-Below the thyroid cartilage and above the first tracheal cartilage is expanded
posteriorly for posterior support
Structures of and within the Trachea - Answer-Mucosa (Goblet Cells, Cilia), Submucosa (Loose
connective tissue), Cartilage Rings (Trachealis Muscle), and Adventitin
Trachea - Answer-Air passageway; has cartilage rings to help keep the air passage open as air rushes in;
branches into right/left bronchus. Contains vocal cords
Bronchi - Answer-Airways in the lungs that lead from the trachea to the bronchioles.
Bronchioles - Answer-Airways in the lungs that lead from the bronchi to the alveoli.
