B IO 202 - Final Lab Exam
Qu estions and an sw er s w ith
accu r ate r ationales(PASSED)
Upper respiratory system - answer nose, nasal cavity, pharynx
Lower respiratory system - answer larynx, trachea, bronchi, lungs
What structures make up the conducting zone? - answer trachea, main
bronchi, lobar bronchi, segmental bronchi, bronchioles, and terminal
bronchioles
What structures make up the respiratory zone? - answer respiratory
bronchioles, alveoli and alveolar ducts.
What are the functions of the interior structures of the external nose -
answer entry point for air
Nasal cavity - answer hollow space behind the nose
Olfactory epithelium - answer a thin layer of tissue, within the nasal
cavity, that contains the receptors for smell
,Nasopharynx - answer
Orphopharynx - answer
Laryngopharynx - answer
Respiratory epithelium - answer pseudostratified ciliated columnar
epithelium
Larynx - answer voice box; passageway for air moving from pharynx to
trachea; contains vocal cords
Epiglottis - answer A flap of tissue that seals off the windpipe and
prevents food from entering.
Vestibular folds - answer (false vocal cords)
Superior to vocal folds
No part in sound production
Help to close glottis during swallowing
, Vocal folds - answer Mucosal folds that function in voice production
(speech); also called the true vocal cords.
Trachea - answer a large membranous tube reinforced by rings of
cartilage, extending from the larynx to the bronchial tubes and
conveying air to and from the lungs; the windpipe.
Right main bronchus - answer shorter, wider, and more vertical than the
left main bronchus
Left main bronchus - answer Slightly narrower and more horizontal than
the right
Carina - answer Point at which the trachea bifurcates (divides) into the
left and right mainstem bronchi.
Lobar bronchi - answer secondary bronchi - bronchial passageways
connecting the mainstem bronchi with individual lobes of the lungs
Segmental bronchi - answer Airways leading into specific lung
segments.
Bronchioles - answer smallest branches of the bronchi, lead to alveoli
