respiratory - phyanalab Flashcards
Respiration: Three Major Steps
Pulmonary ventilation
External respiration
Internal respiration
Moving air in and out of lungs
Pulmonary ventilation
Gas exchange between alveoli and blood
External respiration
Gas exchange between blood and cells
Internal respiration
upper respiratory system
Nose and pharynx
lower respiratory system
Larynx, trachea, bronchi, bronchioles, and lungs
consists of All airways that carry air to lungs
conduction zone
parts included in conduction zone
Nose, pharynx, trachea, larynx, bronchi, bronchioles, and terminal bronchioles
Sites within lungs where gas exchange occurs
respiratory zone
parts of the respiratory zone
Respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli
Warm, humidify, filter/trap dust and microbes
nose
Detect olfactory stimuli
nose
Modify vocal sounds
nose
“Voice box”
larynx
Made largely of cartilage
larynx
cartilages of the larynx
thyroid
cricoid
arytenoids
cartilage of larynx
: V-shaped
“Adam’s apple”: projects more anteriorly in males
Vocal cords “strung” here (and to arytenoids
thyroid cartilage
leaf-shaped piece; covers airway
During swallowing, larynx moves up so —— covers opening into trachea
epiglottis
cartilage of larynx
inferior most portion
cricoid
cartilage of larynx
superior to cricoid
Arytenoids
windpipe
trachea
Anterior to esophagus and thoracic vertebrae
Extends from end of larynx to primary bronchi
trachea
opening in trachea for tube
tracheostomy
enter the lungs medially
primary bronchiu
Measured by spirometer
Lung Volumes
volume of air that can be inhaled beyond tidal volume (TV)
Inspiratory reserve volume (IRV
volume of air that can be exhaled beyond TV
Expiratory reserve volume (ERV)
Air remaining in lungs after a maximum expiration
= residual volume (RV)
TV + IRV
Inspiratory capacity
RV + ERV
Functional residual capacity (FRC)
IRV + TV + ERV
Vital capacity (VC)
VC + RV
Total lung capacity (TLC)
branch of medicine that deals with the study and treatment of disorders associated with the nose, ears, and throat
otorhinolarynogology
study of diseases associated with lungs
pulmonology
divides nasal cavity into left and right sides
nasal septum
separates nasal and oral cavity
hard palate
