PGY 300 RESPIRATORY EXAM PREP
STUDY GUIDE QUESTIONS ANSWERS
COMPLETE SOLUTION BUNDLE
●● airways
Answer: -conduct air
-mouth and nose - pharynx - larynx - trachea
●● alveolar pressure
Answer: -pressure of air inside the lung alveoli
-at rest = 0
-inhalation = -1
-exhalation = 1
●● alveolar ventilation
Answer: -air entering alveoli
-low values of this leads to hypoventilation
-caused by lower than normal volumes of fresh air entering alveoli,
decreased lung compliance, increased airway resistance or CNS
depression -- drug overdose, alcohol poisoning
●● alveoli (singular alveolus)
,Answer: -a series of interconnected sacs and their associated pulmonary
capillaries
-these structures form the exchange surface where oxygen moves from
inhaled air to the blood
-clustered at ends of terminal bronchioles
-make up bulk of lung tissue
●● anatomic dead space
Answer: -another word for airways
-because can't do gas exchange
●● asthma
Answer: -inflammatory condition that is characterized by
bronchoconstriction and airway edema
-can be triggered by exercise or by rapid changes in temperature and
humidity
●● atmospheric pressure
Answer: -remains constant throughout respiration
=0
●● Boyle's law
Answer: P1V1 = P2V2
, ●● bronchioles
Answer: -airways
-can constrict/dilate
-any of the branches in which the primary bronchus divides to
●● bronchoconstriction
Answer: -increases resistance to air flow and decreases the amount of
fresh air that reaches alveoli
-changing of bronchiole diameter
●● bronchodilation
Answer: -caused by response to paracrines
-increased CO2 causes this by relaxing the bronchiolar smooth muscle
●● bronchus
Answer: -airways that divide from the windpipe
●● bulk flow
Answer: -this is equal to the change in pressure / resistance
●● cellular respiration
