respiration
exchange of gases between a living organism and its enviorment.
Components of upper airway
Nasal cavity
Oral Cavity
Pharynx
Nasal Septum
cartilage that separates the right and left nasal cavities
Eustachian tube
a tube that connects the ear with the nasal cavity
nasolacrimal duct
narrow tube that carrinto the nasal cavity terars and debris that have drained from the eye
Nare
nostril
Mucous Membranes
tissures lining body cavities that communicate with the air; usually contains mucus-secreting cells.
Mucus
slippery secretion that lubricates and protects air way surfaces
Pharynx
a muscular tube that extends vertically from the back of the soft palate to the superior aspect of the esophagus
gag reflex
mechanism that stimulates retching , or striving to vomit, when the soft palate is touched.
endotracheal intubation
passing atube into the trachea to protect and maintain the air way and to permit medication administration and deep suctioning
Larynx
the complex structure that joins the pharynx with the trachea
glottis
lip-like opening between the vocal cords.
Sellick's maneuver
pressure applied in a posterior direction to the anterior crioid cartilage that occludes the esophagus.
aspiration
inhaling forign material, such as vomitus, into the lungs.

10-12 cm long tube that connecs the larynx to the main stem bronchi
bronchi
tubes from the trachea into the lungs.

alveolar collapse.
parenchyma
priniciple or esential parts of an organ.

ventilation
the mecheanical process that moves the air into and out of the lungs.

the pressure exerted by each component of a gas maisture.
PA
alveolar partial paressure
Pa
arterial partial pressure
Diffusion
movement of gas from an area fo higher concentration to an area of lower concentration.
