nasal cavity contains mucous membranes on conchae
septum separates left and right sides of the nasal cavity
intercostals muscles of the rib cage that help move the rib cage for breathing
pneumonia infection of the lungs that causes buildup of fluid in lungs
emphysema disease where alveoli become less elastic and may break down
mucosa moist membranous material that warms and moistens air
cilia cell part found in repiratory system - moves mucus
conchae increase surface area of mucous membranes
palate dividing wall between mouth and nasal cavity
sinuses lighten skull - hollow spaces in bones of head
pharynx common passageway for air and food
larynx voicebox
Eustacian tube connects middle ear into nasopharynx
tonsils lymphatic tissue in oropharynx
thryoid cart. Adam's apple; part of larynx
epiglottis directs food into esophagus rather than into trachea
esophagus passageway for food from pharynx to stomach

bronchus large branch of airway; surrounded by cartilage
bronchiole tiny branch of airway; not surronded by cartilage
lungs contain the alveoli
alveoli where diffusion of gases occurs into/out of blood
pleura membranes surrounding the lungs
inspiration process of breathing in
expiration process of breathing out
inspiratory res.extra air that can be breathed in past a normal breath in
expiratory res. extra air that can be breathed out past a normal breath out
tidal volume normal breath in and out (500 ml.)
vital capacity total amount of air that can be exchanged in/out of lungs
residual volume air that is in lungs but that cannot be expelled
spirometer device that measures volume of air flow in/out of lungs
bicarbonate the way that carbon dioxide is carried in the blood
hemoglobin where oxygen is carried in the blood
carbon monoxide poisonous gas that connects to hemoglobin; keeping oxygen off
medulla contains respiratory centers of brain; controls breathing rate
breathing the process of bringing air into and out of the lungs
bronchi more than one bronchus
inhalataion breathing in as pressure in the lungs goes down
exhalation breathing out as pressure in the lungs goes up
diaphragm muscle below lungs that contracts and helps pull air in
medulla the portion of the brain that control breathing rate
