|
primary fuctions of the upper airway
|
1) act as a conductor of air 2) humidify and warm inspired are 3) to prevent foreign materials from entering the tracheobronchial tree 4) involved in speech and smell

Lamina propria
|
submucosal layer of the tracheobronchial tree
|
|
Mast cells
|
important role in the immunologic mechanism. found in the lamina propria near the branches of the vagus nerve
|
|
factors known to slow the rate of the mucociliary transport
|
cigarette smoke, dehydration, positive pressure ventilation, endotracheal suctioning, high inspired oxygen concentrations, hypoxia, pollutants, general anesthetic, parasympatholytics
|
|
what are the chemical indicators released by mast cells

|
Canals of Lambert

Alveolar Epithelium is composed of what types of cells?
|
Type I cell (squamous pneumocyte)
Type II cell (granular pneumocyte) |
|
Pores of Kohn
|
small holes in the walls of the interalveolar septa
|
|
lymphatic vessels
|
found superficially around the lungs just beneath the visceral pleura
|
|
sympathetic nervous system
|
accelerates the heart rate, constricts blood vessels, relaxes the bronchial smooth muscles and raises blood pressure
|
|
para sympathetic nervous system
|
slows the heart rate, constricts the bronchial smooth muscles and increases intestinal peristalsis and gland activity
