-pnea | breathing |
spir/o | breathing |
steth/o | chest |
paransal sinuses | air-filled space in the skill that opens into the nasal cavities |
palate | roof of the mouth; partition between the oral and nasal cavities; divided into the hard and soft palate |
hard palate | bony anterior (front) portion of the palate |
soft palate | muscular posterior (back) portion of the palate |
Pharynx | throat; passageway for food to the esophagus and air to the larynx |
nasopharynx | part of the pharynx directly behind the nasal passages |
orophyarynx | central portion of the pharynx between the roof of the mouth and the upper edge of the epiglottis |
laryngopharynx | lower part of the pharynx, just below the oropharyngeal opening into the larynx and esophagus |
tonsils | oval lymphatic tissues on each side of the pharynx that filter air to protect the body from bacterial invasion; also called palatine tonsils |
adenoid | lymphatic tissue on the back of the pharynx behind the nose; also called pharyngeal tonsil |
glottis | opening between the vocal cords in the larynx |
Lobes | subdivisions of the lung, with two on the left and three on the right |
Pleural cavity | potential space between the visceral and parietal layers of the pleura |
mucous membrane | thin sheets of tissue that line respiratory passages and secrete mucus, a viscid (sticky) fluid |
eupnea | normal breathing |
Bradynea | slow breathing |
Tachypnea | fast breathing |
hypopnea | shallow breathing |
hyperpnea | deep breathing |
dyspnea | difficulty breathing |
apnea | inability to breath |
orthopnea | ability to breath only in an upright position |
wheezes | high-pitched, musical sounds heard on auscultation of the lung as air flows through a narrowed airway; occurs in disorders such as asthma or emphysema |
stridor | high-pitched, crowing sound that occurs with an obstruction in the upper airway (trachea or larynx) |
sputum | material expelled from the lungs by coughing |
hypoxemia | deficient amount of oxygen in the blood |
hypoxia | deficient amount of oxygen in tissue cells |
rhinorrhea | thin, watery discharge from nose (runny nose) |
asthma | panting; obstructive pulmonary disease caused by a spasm of the bronchial tubes or by swelling of the mucous membrane; characterized by paroxysmal (sudden, periodic) attacks of wheezing, dyspnea, and cough |
atelectasis | abnormal dilation of the bronchi with accumulation of mucus |
bronchogenic carcinoma | lung cancer; cancer originating in the bronchi |
croup | acute respiratory infection in infants and young children involving the larynx, trachea, and bronchi causing inflammation; creates a funnel-shaped elongation of tissue causing a distinct 'seal bark' cough |
empyema | accumulation of pus in the pleural cavity; also called pyothorax |
arterial blood gas (ABG) | analysis of arterial blood to determine the adequacy of lung function in the exchange of gases |
PaO2 | abbreviation for partial pressure of oxygen; measurement of the amount of oxygen in the blood |
PaCO2 | abbreviation for partial pressure of carbon dioxide; measurement of amount of carbon dioxide in the blood |
