Respiratory
C6 Respiratory System
Question | Answer |
---|---|
external respiration | inhaling air into lungs and exhaling |
internal respiration | cellular respiration - exchange of gases between blood and tissues |
nasal cavity | consists of mucous membranes and cilia, incoming air is filtered and warmed |
paranasal sinuses | air spaces in skull where mucous is produced that helps to lubricate the nasal cavity |
pharynx | throat |
nasopharynx | contains adenoids/pharyngeal tonsils |
oropharynx | contains palatine tonsils (lymphatic tissue) |
laryngopharynx | handles both food and air, divides into larynx and esophagus |
larynx | voice box |
esophagus | carries food to stomach |
epiglottis | cartilage flap that closes to preven food from entering larynx and trachea |
glottis | opening to the larynx |
palatine tonsils | lymphatic tissue at back of the roof of the mouth, or oropharynx |
pharyngeal tonsils | adenoids in the nasopharynx, upper back wall of the throat |
trachea | windpipe, tube of cartilage rings which divides into two bronchial tubes |
bronchi | 2 bronchial tubes that the trachea divides into at the mediastinum |
mediastinum | space of the chest where trachea divides into two bronchi |
hilum | area where a bronchus, nerves, and blood vessels enter the lung |
bronchioles | smaller tubes |
alveoli | air sacs that facilitate the exchange of oxygen |
pulmonary parenchyma | bronchioles and alveoli |
3 lobes | right lung |
2 lobes | left lung |
pleura | double membrane surrounding lungs |
visceral pleura | innermost membrane lining the lung |
parietal pleural | outermost membrane lining of the lung, closest to ribs |
croup | caused by infection, allergic reactions, or foreign bodies, obstructs passage of air through larynx, causing barking cough and stridor |
stridor | harsh, high pitched sounds made during respiration |
rales | crackles, abnormal crackling sounds when fluid, blood, or pus are in alveoli |
rhonchi | coarse, loud rales caused by secretions in a bronchus |
epistaxis | nosebleed |
diptheria | bacterial throat infection |
pertussis | whooping cough, bacterial throat infectin |
asthma | bronchial spasms and constriction of the bronchial airways which cause dyspnea, wheezing, and coughing |
dyspnea | labored breathing |
bronchiectasis | chronic dilation of bronchial tubes associated with recurring lung infections |
bronchitis | persistent inflammation of the bronchi |
bronchogenic carcinoma | malignant tumors in bronchial pathways, can spread rapidly to the lungs |
cystic fibrosis | inherited disease compromising the function of mucous membranes, causing obstructions (exocrine glands involved) |
tuberculosis | caused by bacilli, producing obstructions called tubercles |
tubercles | swellings caused by tuberculosis |
emphysema | breakdown of alveoli walls through over-inflation causing loss of air exchange |
pneumoconiosis | chronic condition linked to inhaling dust |
pneumonia | inflammation and infection of alveoli producing pus, fluid, and other by-products in the lungs |
anthracosis | black lung disease, caused by inhaling coal dust |
asbestosis | linked to asbestos fibers |
silicosis | caused by inhaling silica or glass |
Grinder's disease | silicosis |
double pneumonia | both lungs affected |
atelectasis | collapsed lung or part of a lung, caused by trauma or blockages |
pulmonary abscess | large collection of pus in lung caused by bacterial infection |
pulmonary edema | swelling or buildup of fluids in bronchioles and alveoli |
pulmonary emobolism | clot in the vessels of the lung |
mesothelioma | tumor in the pleura |
pleural effusion | fluid in the pleural cavity |
pleurisy | pleuritis |
pleuritis | inflammation of the pleura |
pneumothorax | air or gas buildup in the pleural cavity |
sputum | material expelled from chest area of lungs |
spirometer | measures air intake and output |
thoracentesis | insertion of needle or catheter into pleural cavity to obtain fluid, drain effusions, or expand a collapsed lung |
tracheostomy | opening in the trachea if upper respiratory system damaged |
thoracotomy | chest opened to access lungs for biopsies or resection |
lung resection | partial or full removal of lung |
