BIOL 473 Exam 2: respiratory UPDATED
ACTUAL Exam Questions and CORRECT
Answers
what is the respiratory tract divided into? - CORRECT ANSWER - upper and lower tracts
what is the upper res tract? - CORRECT ANSWER - nose
nasal cavities
sinuses
pharynx
and part of larynx
what is lower res tract? - CORRECT ANSWER - larynx
trachea
bronchi
bronchioles
alveolar ducts
alveoli
what act as air conduits? - CORRECT ANSWER - The trachea, bronchi, and larger
bronchioles act as air conduits that bring air to the respiratory bronchioles, alveolar ducts, and
alveoli
where does gas exchange strictly occur? - CORRECT ANSWER - alveoli
what are the two characteristic sounds picked up about the respiratory tract through ausculation?
- CORRECT ANSWER - bronchial
vesicular
, how are bronchial sounds produced? - CORRECT ANSWER - air rushing through the
large respiratory passageways (the trachea and the bronchi).
how are vesicular sounds produced? - CORRECT ANSWER - as air fills the alveolar sacs
and resembles the sound of a rustling or muffled breeze.
what can produce abnormal chest sounds? - CORRECT ANSWER - Diseased respiratory
tissue, mucus, or pus can produce abnormal chest sounds such as rales (a rasping sound) and
wheezing (a whistling sound)
what produce variations in respiratory volumes? - CORRECT ANSWER - sex age size
and physical condition
how much air does normal quiet breathing move? - CORRECT ANSWER - 500 ml of air
in and out of the lungs with each breath
what is tidal volume TV? - CORRECT ANSWER - amount of air inhaled or exhaled with
each breath
under resting conditions (500 ml)
what is inspiratory reserve volume IRV? - CORRECT ANSWER - amount of air that can
be forcefully inhaled after a normal tidal volume inhalation (3100 ml)
what is expiratory reserve volume ERV? - CORRECT ANSWER - amount of air that can
be forcefully exhaled after a normal tidal volume exhalation (1200 ml)
what is vital capacity VC? - CORRECT ANSWER - maximum amount of air that can be
exhaled after a maximal inspiration (4800 ml)
what is the equation for air? - CORRECT ANSWER - VC = TV + IRV + ERV
