MedTerm - module 5 Flashcards
respiration
breathing; process by which oxygen and carbon dioxide are exchanged between the body and the environment
expiration/exhalation
breathing out carbon dioxide from the body
inspiration/inhalation
process of breathing in oxygen
ventilation
the process of both inspiration and expiration
external respiration
work of inhaling and exhaling between the respiratory and the external environment
internal respiration
exchange of inhalation and expiration takes place within the body, the work of the body cells taking in oxygen and giving carbon dioxide
nose
entrance to the respiratory system through which air travels to and from the lungs
nas/o, rhin/o
nose
nasal septum
is the separation of the nose (midline portion)
sept/o
septum
paranasal sinuses
air containing cavities in the bones around the nose
sinus/o

double folded membranous layer which folds over to also form the lining of the chest wall
pleur/o
pleaura
pleural cavity
space separating the layers of the pleura contains a small amount of fluid that helps to keep the lungs as they expand and contract during breathing
intrapleural
anything occurring within the pleura
rhinitis
inflammation of the mucous membranes of the nose, usually accompanied by inflammation and nasal discharge
pansinusitis
inflammation of the sinuses
rhinomycosis
fungal infection of the nasal membrane

interruption of the airflow cause by the relaxation and repetitive collapse of the pharyngeal muscles during sleep
