BIO 669 QUESTIONS AND ANSWERS LATEST UPDATE
(GRADED A+)
compression atelectasis
d/t external forces pushing on acini
absorption atelectasis
blockage of acini and air becomes absorbed
surfactant impairment atelectasis
decreased production or inactivation of surfactant
bronchiectasis
abnormal dilation of the bronchi d/t chronic inflammation
bronchiolitis
inflammation of the small airways; leads to blockage of the alveoli and increased resistance/decreased
compliances
bronchiolitis is most common in
children
children s/s of bronchiolitis
wheezing, tachypnea, tachycardia,
Adult bronchiolitis is usually caused by ____
toxic gases or a viral infection
pulmonary fibrosis
alveolar membrane destruction; decreased O2 diffusion
pneumoconiosis
damage to the alveoli d/t inorganic particles
ex. silica, asbestos, coal
Allergic alveolitis
aka hypersensitivity pneumonitis
allergic reaction to inhaled fumes/particles
regulated by IgE
pulmonary edema is:
excess water in the lungs
