Respiratory 11 Flashcards
nose
anatomic structure at the entrance to the respiratory system that conducts, warms, humidifies, and clean inhaled air
nasal cavity
the space on either side of the nasal septum extending from the nares (nostrils) to the pharynx
nasal septum
dividing wall between the right and left nasal cavities
paranasal sinuses
paired air-filled cavities in the bones of the face that connected to the nasal cavity; these include the frontal, sphenoidal, maxillary, and ethmoidal sinuses
pharynx
throat; space between the mouth that serves as a passage for food from the mouth to the esophagus and for air from the nose and mouth to the larynx; made up of the nasopharynx, oropharynx, and laryngopharynx
adenoids
pharyngeal tonsil located on the posterior wall of the nasopharynx that enlarges during childhood and shrinks during puberty
tonsils
lymphatic structures including the pharyngeal tonsil (adenoids), palatine tonsil, and lingual tonsil
cilia
fine hair-like projections lining the mucous membranes
larynx
air passageway located between the pharynx and the trachea that holds the vocal cords; voice box
epiglottis
flap of cartilage that covers the upper region of the larynx during swallowing to prevent food or other matter from entering the lungs
glottis
part of the larynx consisting of the vocal folds (vocal cords) and the slit-like opening between the folds
trachea
air passage extending from the larynx into the thorax; windpipe
bronchi
two main branches (left bronchus and right bronchus) off the trachea that convey air to and from the lungs
carina
cartilaginous ridge at the point where the trachea divides into the two (right and left) bronchi
alveoli
tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide occurs between the lungs and blood
bronchioles
finer subdivisions of the bronchi located in the lungs
lungs
paired organs of breathing in which blood is aerated
lobes
subdivisions of the lungs: there are three on the right (upper, middle, and lower) and two on the left (upper and lower)
pleura
serous membrane surrounding the lungs and lining the walls of the pulmonary (lung) cavities
parietal layer
outer layer of the pleura that attaches to the chest wall; parietal pleura
pleural cavity
space between the layers of the pleura
visceral layer
inner layer of the pleura that attaches to the lungs; visceral pleura
thorax
chest; upper trunk between the neck and abdomen; formed by the sternum, the thoracic vertebrae, and the ribs, extending to the diaphragm
diaphragm
muscular partition between the abdominal and thoracic cavities; the contraction and relaxation of the diaphragm causes inspiration and expiration
mediastinum
area of the thoracic cavity between the lungs that contains the heart, aorta, esophagus, trachea, and thymus
airway
any part of the respiratory tract through which air passes during breathing
eupnea
normal breathing
expiration;
exhalation; process of breathing out
external respiration; breathing
exchange of respiratory gases (oxygen and carbon dioxide) in the lungs
inspiration
inhalation; process of breathing in
internal respiration
exchange of gases between the blood and the tissues; tissue respiration
patent
open or unobstructed
respiration
the process involving the exchange of oxygen and carbon dioxide between the environment and body cells; breathing or pulmonary ventilation
sputum
mixture of saliva and mucus coughed up (expectorated) from the respiratory tract; phlegm
ventilation
movement of gases into and out of the lungs; respiration
