trache-
Windpipe
Upper respiratory
Nose, nasal cavities, pharynx, larynx
Lower respiratory
Trachea, bronchi, bronochioles, conducting bronchioles, terminal bronchioles, respiratory bronchioles alveoli
Conducting zone
acts to transport air
Respiratory zone
region where gas exchange occurs
Air spaces
Cervical air spaces, clavicular air sac, cranial thoracic air sac, caudal thoracic air sacs,abdominal air sacs, lungs
Components
Trachea, syrinx, bronchi, lungs: mesobronchi, ventrobronchi, dorsobronchi, parabronchi, air capillaries
Compliance
Ability to stretch
Elasticity
tendency to return to original size after distention
Surface Tension
the tension due to the attraction between like molecules
Mammal Pulmonary surfactant
Lowers surface tension between the alveolar membranes. made in alveolar cells in late pregnancy
Avian pulmonary surfactant
lowers surface tension between air capillary membranes. made from laminated osmiophilic bodies on day 18
Functions of the Upper respiratory system
Filter, Heat, Humidify
Tidal Volume
Volume of air moving in and out during respiration
Minute Respiratory Volume
Tidal volume times respiration rate
Resting tidal volume
Volume of air moving in an out during respiration at rest
Vital capacity
Maximum volume of air inspired after maximum expiration
Residual volume
the air that remains in the airways after maximal forced expiration and thus cannot be removed
Total lung capacity
The sum of vital capacity and residual volume
Pathway for air for the avian
larynx to trachea to syrinx to bronchus to mesobronchus fills the rear most air sacs first (abdominal air sacs and caudal thoracic air sacs). Back to the mesobronchus to the dorsobronchus to the parabronchus to the air capillaries, back to the parabronchus to the ventrobroncus and back to the mesobronchus. then fills the remaining air sacs (cranial thoracic air sac, clavicular air sac, and cervical air sac) back to the mesobronchus. then out the bronchus the syrinx the trachea and finally the larynx
