Pathophysiology Midterm 2026
Exam Questions and Correct
Answers | New Update
Asthma - ANSWER ✔✔Chronic disease due to bronchoconstriction
and an excessive inflammatory response in the bronchioles
What are 5 s/s of asthma - ANSWER ✔✔coughing
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 - ANSWER ✔✔smaller passageways that originate from
the bronchi that become the alveoli
3 layers of the bronchioles - ANSWER ✔✔innermost layer
middle layer - lamina propria
outermost layer
lamina propria - ANSWER ✔✔the middle layer of the bronchioles
structure of the lamina propria - ANSWER ✔✔embedded with
connective tissue cells and immune cells
purpose of the lamina propria - ANSWER ✔✔white blood cells are
present to help protect the airways
,How does the lamina propria effect the lungs in regards to asthma -
ANSWER ✔✔the WBCs protective feature goes into overdrive
causing an inflammatory response that damages host tissue
What does the innermost layer of the bronchioles contain - ANSWER
✔✔columnar epithelial ells and mucus producing goblet cells
What does the outermost layer of the bronchioles contain - ANSWER
✔✔smooth muscle cells
what does the outermost layer of the bronchioles do - ANSWER
✔✔control the airways ability to constrict and dilate
alveolar hyperinflation - ANSWER ✔✔When 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? - ANSWER ✔✔the 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 - ANSWER
✔✔tiotropium and ipratropium
What do anticholinergics do in the lungs? - ANSWER ✔✔These
drugs block the effects of the parasympathetic nervous system
- increasing bronchodilation
MOA of anticholinergic drugs for asthma - ANSWER ✔✔the
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 - ANSWER ✔✔inflammation of the bronchial tubes
3 characteristics of bronchitis - ANSWER ✔✔bronchial inflammation
hypersecretion of mucus
chronic productive cough for at least 3 consecutive months for at least 2
successive years
