Asthma - ANSWERChronic disease due to bronchoconstriction and an excessive
inflammatory response in the bronchioles
What are 5 s/s of asthma - ANSWERcoughing
wheezing
shortness of breath
rapid breathing
chest tightness
Pathophysiology of asthma (5) - ANSWER-airway inflammation, bronchial hyper-
reactivity and smooth muscle spasm
-excess mucus production and accumulation
-hypertrophy of bronchial smooth muscle
-airflow obstruction
-decreased alveolar ventilation
Bronchioles - ANSWERsmaller passageways that originate from the bronchi that
become the alveoli
3 layers of the bronchioles - ANSWERinnermost layer
middle layer - lamina propria
outermost layer
lamina propria - ANSWERthe middle layer of the bronchioles
structure of the lamina propria - ANSWERembedded with connective tissue cells and
immune cells
purpose of the lamina propria - ANSWERwhite blood cells are present to help protect
the airways
, How does the lamina propria effect the lungs in regards to asthma - ANSWERthe WBCs
protective feature goes into overdrive causing an inflammatory response that damages
host tissue
What does the innermost layer of the bronchioles contain - ANSWERcolumnar epithelial
ells and mucus producing goblet cells
What does the outermost layer of the bronchioles contain - ANSWERsmooth muscle
cells
what does the outermost layer of the bronchioles do - ANSWERcontrol the airways
ability to constrict and dilate
alveolar hyperinflation - ANSWERWhen air is unable to move out of the alveolar like it
should due to bronchial walls collapsing around possible mucus plug thus trapping air
inside
how does hyperinflation occur? - ANSWERthe ongoing inflammatory process of asthma
produces mucus and pus plug that the bronchial walls collapse around
Effect of hyperinflation of the alveolar - ANSWER-expanded thorax and hypercapnia
(retention of CO2)
- respiratory acidosis
What are two anticholinergic drugs used for asthma - ANSWERtiotropium and
ipratropium
What do anticholinergics do in the lungs? - ANSWERThese drugs block the effects of
the parasympathetic nervous system
- increasing bronchodilation
MOA of anticholinergic drugs for asthma - ANSWERthe parasympathetic system is
stimulated by the vagal nerve to release acetylcholine which binds to the cholinergic
receptors of the respiratory tract to cause bronchial constriction = decreased airflow
- blocking the cholinergic receptors prevents acetylcholine binding preventing the
bronchial constriction
bronchitis - ANSWERinflammation of the bronchial tubes
3 characteristics of bronchitis - ANSWERbronchial inflammation
hypersecretion of mucus
chronic productive cough for at least 3 consecutive months for at least 2 successive
years
