The process of gaseous exchange between the individual and the environment
respiration
3 process of respiration
Ventilation, diffusion, perfusion
provide a route for air to move between the outside atmosphere and the lungs. They also clean, humidity, and warm the incoming air.
Upper airways
structures pull in air from the upper respiratory system, absorb the oxygen, and release carbon dioxide in exchange
Lower airways
from posterior nares to soft palate
nasopharynx
from soft palate to hyoid bone
oropharynx
from hyoid bone to esophagus
Laryngopharynx
Triangular shaped, primarily of cartilage
larynx
opening between true vocal cords, narrowest part of larynx
Rima glottidis
true vocal cords and rima glottidis
Glottis
Adam's apple, largest cartilage
Thyroid
leaf shaped moves up and down during swallowing to prevent food from entering trachea
Epiglottis
point of attachment for vocal cords
Aretynoid
Functions of the larynx
Air passageway, Filters, warms, humidifies air, protects airway against entrance of solid or liquids, voice production.
is the wind pipe, made of C shaped rings of cartilage, incomplete on the posterior surface.
Trachea
Fluid inside each alveoli, prevents alveoli from collapsing as air moves in and out
Surfactant
barrier across which gas is exchanged
respiratory membrane
If blood pressure is elevated the respiratory rate becomes slow=
RESPIRATORY ACIDOSIS.
_______________is a condition that occurs when your lungs can't remove all of the carbon dioxide produced by your body.
Respiratory acidosis
IF Blood pressure is decreased, the respiratory rate becomes rapid, hypotension leads to___________
respiratory alkalosis
______________ is a condition THAT occurs when you breathe too fast or too deep and carbon dioxide levels drop too low.
Respiratory alkalosis
Abnormal lung sounds
Diminished lung sounds and adventitious breath sounds
loud, high-pitched sounds, around the trachea
Bronchial
medium pitched sounds, 1st and 2nd intercoastal space beside the sternum
Bronchovesicular
Soft, low-pitched sounds, entirety of lung fields
Vesicular
decreased fremitus occurs in ___________ and _________
emphysema and pneumothorax
Increased in fremitus occurs in _________and __________
pneumonia and tumor in the lung
Percussion Tones: Heard over normal lung tissue
Resonant
Percussion Tones: Heard over airless tissue
Flat
Percussion Tones: occur over dense lung tissues such as a tumor or consolidation
dull
Percussion Tones: indicates a large tension pneumothorax
Tympanic
Produced by emphysema and pneumothorax
Hyperresonant
is an abnormal sound heard during percussion in adults. It represents air trapping such as in obstructive lung diseases.
Hyperresonance
Heard over lungs
Resonance
Heard over heavy muscles and bones
Flat
Heard over heart and liver
dullness
Heard over stomach
Tympany
Vesicular is heard over most of lung fields soft and short expirations
Normal
Bronchovesicular is heard over main bronchus area and over upper right posterior lung field-expiration equals inspirations
normal
Bronchial is heard only over trachea- loud and long expiration
normal
Bronchial is heard over peripheral lung fields
abnormal
Bronchovesicular is heard over peripheral lung fields
abnormal
voice sounds: ninety-nine
Bronchophony
voice sounds: one, two, three
Whispered pectoriloquy
voice sounds: e-e-e-e
Egophony
__________ is used in mantoux test
Purified protein derivative
positive in mantoux test is ___________
10mm or more
positive in HIV is ____________
5mm
