what are key aspects of respiratory anatomy and their physiology
Upper airway= 30-50% of dead space
Air has 70-80% r. Humidity in nose; 100% by carina
Trachea=16-20 cartilage rings; smooth muscle backside, 10-13 cm long
Cords at c4
Carina= located at T4-T6
Left Bronchus= 40-60 degree angle; 2 segmental
Right bronchus=25 degree angle, 3 subsegmental, first lobar bronchi at 2.5 cm
Lobar Bronchi=3 on right, 2 on left
Segmental bronchi-18 of them
Subsegmental bronchi- most of the airway resistance below glottis (80%) occurs here
Bronchioles-1 mm diameter; the small (peripheral) airways begin here
Terminal bronchioles- last strictly conductive airway
Respiratory bronchioles- beginning of parenchyma (air exchange)
Alveolar ducts- 35% of alveoli come from ducts
Alveolar sacs- (65% of alveoli come from sacs)
Alveoli-9x9meters (80 m2 or 29x29 feet)
