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
Disease caused by destruction of the elastic tissue of the lung causing decrease in elastic recoil of the lungs
Emphysema
Walls of alveoli are destroyed by enzymes due to inflammation
Emphysema
Productive cough for 3 months per year for 2 years
Chronic Bronchitis
Inflammation of the bronchi that produces excessive secretions that are expectorated
Chronic Bronchitis
Acute, reversible, inflammatory, obstructive condition affecting both adults and children
Asthma
Hereditary autosomal recessive trait located on chromosome 7
Cystic Fibrosis
One or more arteries in the lungs become blocked
Pulmonary Embolism
Club Fingers
Tissue hypoxia
Test to diagnose cystic fibrosis
Sweat
Lack of gas exchange in alveoli due to alveolar collapse or fluid consolidation
Atelectasis
Excess fluid which accumulates in the pleura
Pleural effusion
High or low pitch sounds
Wheeze
Very high pitched wheeze that can be heard with inspiration
Stridor
Bubbles or pops
Crackle
Increased total lung volume
Emphysema
