chapter 8 terminology Flashcards
respiration
activity of various processes that supply oxygen to all body cells and remove carbon dioxide
breathing is called
pulmonary ventilation or ventilation
respiratory system
consist of a series of passages that bring outside air in contact with special structures that lie close to blood capillaries where oxygen and cardon dioxide are exchanged
inspiration / inhalation
air in
expiration / exhalation
air out
pleura
membrane that surrounds the lung and lines the walls of the chest cavity
URT
upper respiratory tract
- nose
- nasal cavity
- pharynx
- larynx
LRT
lower respiratory tract
- trachea
- bronchi
- bronchioles
- alveoli
- lungs
alveoli
air sacs of the lungs where oxygen is exchanged for waste cardon dioxide
epiglottis
lid like structure that covers that larynx during swallowing
oximeter
measure % of hemoglobin saturation with oxygen in the blood
normal respiration rate
15-20
brady respiration rate
bradypnea under 12
tachy respiration rate
tachypnea over 20
spir/o
to breathe
deficiency of oxygen
hypoxia and anoxia
nares
nostrils
nasal septum
separates the nostrils left and right
esophagus
Musculomembranous canal extending from the pharynx to the stomach
VC
VITAL CAPACITY
the largest volume of air that can be exhaled after maximum inspiration
polyp
small tumorlike growth protruding from a mucus membrane
sputum
material raised from the mucus membranes of the respiratory tract often expelled by coughing
glottis
consists of the vocal cords or folds and the opening between them
Tripod position
eases breathing for a patient with CAL (chronic airflow limitation)
