HEALTHASSESSMENT EXAM QUESTIONS AND ANSWERS
,Pathophysiology of respiratory system deals with Pathophysiologic
mechanisms, physiologic
basis of selected
diagnostic tests and
clinical manifestations
of:
Dyspena, hypoxemia,
hypercapnea
Disorders of inflation
(pleural disorders,
pneumonia, atelectasis)
Obstructive diseases
(asthma, COPD)
Vascular diseases (PE)
Upper airway structures Mouth
Oropharynx
Nasal pharynx
Larynx
Upper air way purpose: Purpose:
Conduction
Humidification
Protection
Lower airway structures
-Tracheobronchial tree
-Trachea-5th vertebre
-R+L main stem bronchi -
Secondary and tertiary
bronchus
-Bronchioles and
terminal bronchioles
-Alveolar ducts
-Alveoli
, Purpose of the lower airway Protection, gas exchange
Lower airway purpose Purpose: Protection, gas
exchange
____________ lobe more likely for PNAs- because.... right lower lobe more
likely for PNAs- because
its easier for fluid to
collect
Dead space Dead space: area where
we have air but do not
have exchange…
because we don't have
suitable circulation
Tracheobronchial Tree has___________ generations. 26 generations
generations 0-15 0-15: conducting zones
generations 5-15 5-15: Continued division
of bronchioles ->
terminal bronchioles
generations 16-26 16-26: Transitional and
respiratory zones
Airway membranes: Columnar epithelium Columnar
epitheliumglands, cilia,
