· the process of gaseous exchange between the individual and the environment.
RESPIRATION
3 Processes 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 AIWAYS
· from the posterior nares to the soft palate
Nasopharynx
· from the soft palate to the hyoid bone
Oropharynx
· from the hyoid bone to the esophagus
Laryngopharynx
· triangular-shaped, primarily cartilage
Larynx
· opening between the true vocal cords; narrowest part of the larynx
Rima glottids
· true vocal cords and rima glottidis
Glottis
Three largest cartilage in larynx:
epiglottis, cricoid, thyroid
adam's apple
Thyroid
leaf-shaped, moves up and down during swallowing to prevent food from entering the trachea
Epiglottis
point of attachment for vocal cords
Arytenoid
fluid inside each alveoli prevents alveoli from collapsing as air moves in and out.
Surfactant
barrier across which gas is exchanged
Respiratory membrane
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
is a condition that occurs when you breathe too fast or too deep and carbon dioxide levels drop too low.
respiratory alkalosis
heard over normal lung tissue.
resonant
heard over airless tissue.
Flat
occurs over dense lung tissues, such as a tumor or consolidation.
Dullness
indicates a large tension pneumothorax.
Tympanic
produced by emphysema and pneumothorax.
Hyper resonant
is an abnormal sound heard during percussion in adults. It represents air trapping, such as in obstructive lung diseases.
Hyperresonance
heard over the lungs
· Resonance
over heavy muscles and bones
· Flat:
heart, liver
· Dullness:
(stomach)
· Tympany
