respiratory system

respiratory systemchapter 7
atel/o incomplete, imperfect
bronch/o, bronchi/o bronchial tube, bronchus
cyan/o blue
-ectasis, ectasia stretching, dilation, enlargment
laryng/o larynx, throat
ox/i, ox/o, ox/y oxygen
pharyng/o pharynx, throat
phon/o, -phonia sound, voice
pleur/o pleura, side of body
-pnea breathing
pneum/o, pneumon/o, pneu- lung, air
pulm/o, pulmon/o lung
tachy- fast, rapid
thorac/o, -thorax chest
trache/o, trache/i trachea, windpipe
upper respiratory tract nose, mouth pharynx, epiglottis, larynx, and trachea
lower respiratory tract brochial tree and lungs
nasal cavity nasal septum divides into 2 sections, mucous membrane lines nose and repiratory system secretes mucus to moisten warm and filter air, cilia thin hairs filter air, olfactory reeptors sense of smell
tonsils protect body from invading organisms
4 paranasal sinuses air filled cavity within a bone, maxillary, frontal, ethmoid, and sphenoid
3 divisions of the pharynx nasopharynx posterior to nasal cavity and continues down behind mouth, oropharynx visible when looking into the mouth shared by respiratory and digestive system,laryngopharynx continues sown to openings of esophagus and trachea
protective swallowing mechanisms soft palate, posterior portion of roof of mouth closes off nasopharynx, epiglottis at base of tongue closes off laryngopharynx
larynx voice box, triangular chamber located between pharynx and trachea, held open by series of 9 cartilages largest is thyroid cartilage (adam's apple), vocal cords open while breathing and closed to vibrate while talking
trachea windpipe, extends from neck into chest, infront of esophagus, held open by series of c shaped cartilage rings
broncial tree divides into 2 branches called bronchi, continues to divid into smaller bronchi, bronchioles are smallest branches of bronchi
alveoli air sacs, very small grapelike clusters at end of each bronchiole, surrounded by pulmonary capillaries, gas exchange through walls of alveoli
lungs R lung: superior, middle, and inferior lobes, L lung: superior and inferior lobes, lobes limit infection to one at a time
mediastinum interpleural space, located between lungs, contains thoracic vicera including heart, aorta, esophagus, rachea, bronchial tubes and thymus gland
pleura multilayered membrane around each lung, parietal pleura-outer layer, visceral pleura-inner layer
plerual space pleural cavity, airtight place betewwn fold of pleural membranes, contains watery fluid for lubrication during respiration
diaphragm muscle that separates thoracic cavity from abdomen, contraction and relaxation of muscle makes breathing possible
phrenic nerve stimulates diaphragm and causes it to contract
phren/o diaphragm, mind
otolaryngologist specializes in diagnosing and treating diseases and disorders of ears, nose and throat, ENT
pulmonologist physician specializing in diagnosing and treating diseases and disorders of lungs and associated tissues
respiratory therapist provides treatment to ease or correct breathing problems
chronic obstructive pulmonary disease COPD, general term to describe respiratory conditions characterized by chronic airflow limitations
asthma chronic allergis disorder, episodes of severe breathing difficulty, coughing and wheezing
bronchiextasis chronic dilation of bronchi or bronchioles resulting from earlier lung infection that was not cured
emphysema progressive loss of lung function due to decrease in number of alveoli, enlargment of remaining alveoli and progressive desturction of their walls
epistaxis nosebleed
pertussis whooping cough
upper respiratory infection acute nasopharyngitis, common cold
paroxysmal sudden or spasmlike
pleurisy inflammation of visceral and parietal pleura in thoracic cavity
pneumothorax accumulation of air or gas in pleural space causing lung to collapse
effusion escape of fluid from blood or lymphatic vessels into the tissues or a cavity
pleural effusion abnormal escape of fluid into pleural cavity that prevents lung from fully expanding
empyema pyothorax, accumulation of pus in pleural cavity
hemothorax accumulation of blood in pleural cavity
hemoptysis spitting of blood or blood stained sputum from lungs or bronchial tubes
-ptysis spitting
acute respiratory distress syndrome ARDS, type of lung failure resulting from many different disorders that cause pulmonary edema
atelectasis collapsed lung, lung fails to expand because air cannot pass beyond bronchioles that are blocked by secretions
tuberculosis TB, infecious disease caused by mycobacterium tuberculosis
exudate accumulated fluid in a cavity that has penetrated through vessel walls into the adjoining tissue
pneumonia inflammation of lungs in which air sacs fill with pus and other liquid
mian causes of pneumonia bacterial, biruses, fungi, or inhaled substances like chemical irritants or vomit
aspiration inhaling or drawing foreign substance sucha s food into upper respiatory tract, or withdrawal by suction of fluids or gases from body cavity
pneumoconiosis abnormal condition caused by dust in lungs that develops after years of environmental or occupational contact
anthracosis black lung disease (anthrac-coal dust)
byssinosis brown lung disease, caused by cotton, flax, or hemp dust
silicosis grinder's disease, caused by silica dust or glass dust
cystic fibrosis CF, genetic disorder, lungs and digestive system are clogged with large quantities of abnormally thick mucus
dyspnea shortness of breath
asphyxia pathologic changes caused by lack of o2 in air
sputum phlegm that is ejected through mouth
spirometry testing method using spirometer to record volume of air inhaled or exhaled adn length of time each breath takes
stoma opening on body surface, natural: a pore, surgical
