Answer 3

chronic bronchitis, asthma, emphysema

Question 4

chronic bronchitis

Answer 4

inflammation, mucus secretion, obstruction of airway

Question 5

asthma

Answer 5

hypersensitivity, mucus production, bronchoconstriction, obstruction of air flow

Question 6

emphysema

Answer 6

enzyme digestion of proteins like elastin

Question 7

smaller the radius

Answer 7

larger the resistance

Question 8

Underlying pathophysiology of asthma

Answer 8

IgE and mast cell degranulation, causing inflammatory mediators(histamines) to be released, causing smooth muscle contraction, increased secretions

inflammation of bronchi

Answer 10

bronchitis

inflammatory obstruction of the bronchioles, smooth muscle constriction

Answer 12

bronchiolitis

Question 14

abnormal permanent enlargement of gas exchange airways accompanied by destruction of alveolar walls

Answer 14

emphysema

Question 15

primary emphysema

Answer 15

inherited deficiency of a1-antitrypsin

Question 16

what inhibits the action of proteolytic enzymes

Answer 16

Answer 17

can be both

Question 18
