Which pulmonary defense mechanism propels a mucous blanket that entraps
particles moving toward the oropharynx?
A) nasal turbinates
B) alveolar macrophages
C) cilia
D) irritant receptors on the nares
Give this one a try later!
Ans: C- cilia
What event is characteristic of the function in Zone 1 of the lung?
A) blood flow through the pulmonary capillary bed increases in regular increments
B) alveolar pressure is greater than venous pressure but not greater than arterial
pressure
, C) the capillary bed collapses and normal blood flow ceases
D) blood flows through Zone 1, but is impeded to a certain extent by alveolar pressure
Give this one a try later!
Ans: C- the capillary bed collapses and normal blood flow ceases
Which factor contributes to the production of mucus associated with chronic
bronchitis?
A) airway injury
B) pulmonary infection
C) increased goblet cell size
D) bronchospasms
Give this one a try later!
Ans: C- increased goblet cell size
Clinical manifestations that include unexplained weight loss, dyspnea on exertion, use
of accessory muscles, and tachypnea with prolonged expiration are indicative of
which respiratory disorder?
A) chronic bronchitis
B) emphysema
C) pneumonia
D) asthma
