Respiratory Systems Disorders Flashcards
Exchange of gas that occurs in the alveolar capillary membranes between atmospheric air and the pulmonary capilaries
External Respiration
Takes place at the tissue capillary level between the tissues and the surrounding capillaries
Internal respiration
Pressure in the lungs
760 mm Hg
Diaphragm and external intercostals are the prime movers
Quiet inspiration
Muscles that pull the ribs up are also called into action
Deep inspiration
Muscles that stabilize and or elevate the shoulder girdle and elevate the ribs
Forced inspiration
Passive process
Quiet expiration
Brings in muscles that can pull down on the rib and muscles that can compress the abdomen
Forced Expiration
The amount of air inspired and expired during resting ventilation
Tidal volume
The amount of air that can be inspired but is usually kept in reserve
Inspiratory reserve volume
The quantity of air that can potentially be exhaled beyond the end of a tidal exhalation
Expiratory reserve volume
Lungs are not completely emptied of air even after maximally exhaling the ERV
Residual Volume
Tidal volume plus the inspiratory reserve volume
Inspiratory capacity
Combination of residual volume and expiratory reserve volume
Functional Residual capacity
the total volume of air within the lungs that is under volitional control
Vital Capacity
