Pathophysiologic
mechanisms, physiologic
basis of selected
diagnostic tests and
clinical manifestations
of:
Dyspena, hypoxemia,
Pathophysiology of respiratory system deals with
hypercapnea
Disorders of inflation
(pleural disorders,
pneumonia, atelectasis)
Obstructive diseases
(asthma, COPD)
Vascular diseases (PE)
Mouth
Oropharynx
Upper airway structures
Nasal pharynx
Larynx
Purpose:
Conduction
Upper air way purpose:
Humidification
Protection
-Tracheobronchial tree
-Trachea-5th vertebre
Lower airway structures -R+L main stem bronchi
-Secondary and tertiary
bronchus
-Bronchioles and
,2
terminal bronchioles
-Alveolar ducts
-Alveoli
Purpose of the lower airway Protection, gas exchange
Purpose: Protection, gas
Lower airway purpose
exchange
right lower lobe more
likely for PNAs- because
____________ lobe more likely for PNAs- because....
its easier for fluid to
collect
Dead space: area where
we have air but do not
Dead space have exchange…
because we don't have
suitable circulation
Tracheobronchial Tree has___________ generations. 26 generations
generations 0-15 0-15: conducting zones
5-15: Continued division
generations 5-15 of bronchioles ->
terminal bronchioles
16-26: Transitional and
generations 16-26
respiratory zones
Columnar epithelium-
Airway membranes: Columnar epithelium glands, cilia, mucus -
mucociliary blanket
Airway membranes: _________________ is in the bronchioles Cuboid epithelium in
bronchioles
, 3
Squamos epithelium in
Airway membranes: _________________ is in the alveoli
the alveoli
consists of:
-Branch of terminal
bronchiole
-Arteriole: carry
deoxygenated blood
-Pulmonary capilaries
Lobuole-functional unit consists of
-Venule: collects
oxygenated blood
-Gas exchanges in
terminal broncioles,
alveolar ducts, and
alveoli
-Type I Cells
Alveolar Structure cells -Type II Cells
-Macrophage-dust cells
Type 1 Cells-> 90% of
surface area
Type 1 Cells flat, epithelial cells
across which gas
exchange takes place
Type II Cells->produce
surfactant
surface tension in alveoli
Type II Cells prevent their collapse
ease lung inflation
prevent fluid
accumulation
Macrophage Macrophage-dust cells
Scavengers: move
around and phagocytize
