lungs: mechanics of respiration Flashcards
in between the ribs
intercostal space
internal organs in main cavities
viscera
pleurae
serous membrane lining for lungs
protects lower airway from foreigns
upper airway
respiratory system supplies O2 to cells and removes CO2 by __
ventilation and diffusion
increased CO2 levels increases __
respiratory rate
pons and medulla
regulates CO2 and O2 levels
process of moving gas in and out of lungs through inspiration and expiration
ventilation
fever with increased breathing rate is increase risk for
sepsis
heart arch of aorta superior vena cava lower esophagus lower part of trachea
right and left pleural cavities
O2 and CO2 move from high to low concentration
diffusion
sternum components
manubrium
body
xiphoid process
if fever, check to see if __ matches
increase respirations
homeostasis is a __ balance
acid-base balance
upper airway includes
nose
pharynx
larynx
intrathoracic trachea
hypoventilation to
increase CO2
intercostal space
- in between the ribs
- named according to rib immediately above it
manubrium
body
articulate with the first 7 ribs
serous membrane lining for lungs
pleurae
hyperventilation to
decrease CO2
space between pleural sacs that contain viscera of chest except lungs and pleurae
right and left pleurae cavities
right and left pleural cavities include
heart arch of aorta superior vena cava lower esophagus lower part of trachea
conducts air to lower airway
upper airway
ICS
intercostal space
trachea right main stem bronchi left main stem bronchi segmental bronchi subsegmental bronchi terminal bronchioles
lower airway
mediatstinum position
middle of the chest
manubrium
body
xiphoid process
sternum components
warms, filters, and humidifies inspired air
upper airway
__ open into alveolar ducts and terminate in multiple alveoli
bronchioles
lower airway includes
trachea right main stem bronchi left main stem bronchi segmental bronchi subsegmental bronchi terminal bronchioles
functions of upper airway
- conducts air to low airway
- protect lower airway from foreigns
- warms, filters, humidifies
mediastinum
right pleural cavity
left pleural cavity
main structures within thorax
main structures within thorax
mediastinum
right pleural cavity

sternum are about __ inches long
7
gas exchanges occur in
alveoli
articulate with the first 7 ribs
manubrium
body
diffusion
O2 and CO2 move from high to low concentration
nose

intrathoracic trachea
upper airway include
infection
sepsis
regulates CO2 and O2 levels
pons and medulla
bronchi are subdivided into
bronchioles
with the first 7 ribs
