TermDefinition
External Respiration breathing, exchange of air between the lungs and external environment. (sacs, capillaries)
Internal Respiration Exchange of gases (co2-o2) Capillaries to tissue
Nares air enters (nostrils)
Nasal cavity Air passes after nares
Cilia mucous membrane and fine hairs
Paranasal sinuses Hollow spaces in the skull that communicate with the nasal cavity
Nasopharynx contains pharyngeal tonsils, or adenoids (collection of lymphatic tissue) more in childern*
Oropharynx Below Nasopharynx, closer to the mouth
Palatine tonsils Two rounded masses of lymphatic tissue
Laryngopharynx Serves as a common passageway for food from the mouth and air from the nose. divides the larynx and esophagus
Epiglottis a flap of cartilage attached to the root of the tongue, prevents choking.
Mediastinum space in the center of the chest
Bronchi tubes
Bronchioles small bronchial branches
Terminal Bronchiole narrows into alveolar ducts
Alveoli Air sacs
Capillary accepts oxygen from alveolus and deposits CO2
Erythrocytes Carries oxygen in the body and brings co2 back to the lungs
Pleura double-layered membrane
Parietal Pleura Outer layer of membrane near the ribs
Visceral Pleura thin, watery fluid moistens the pleura and facilitates movements of the lungs.
Lobes division of the lungs ( right has 3, left has 2)
Apex uppermost part of the lung
Base lower part of the lung
Hilum midline region where blood vessels, nerves, lymphatic tissue, and bronchial tubes enter and exit
Diaphram muscle separating the thorax from the abdominal cavity, and aids breathing
Inhalation(inspiration) Contracts/desends (Breathing in)
Exhalation(expiration) Relaxes and ascends (breathing out)
auscultation Listening to sounds of the body
Percussion Tapping on a surface
Pleural Rub Scratchy sound
Rales(crackles) "wet pop" crackling sound
Rhonchi Loud rumbling sounds (Think mucus)
Sputum Mucus coming out
Stridor Strained, high pitched (like smoke from fire)
Wheezes Whistling sounds (asthma)
Croup viral infection barking cough
diphtheria Acute infection of the throat bacterium
epistaxis Nosebleed
pertussis whooping cough
asthma signs and symptoms of wheezing and cough.
bronchiectasis chronic dilation of a bronchus
chronic bronchitis inflammation of bronchi (over a long time) COPD
Cystic fibrosis Think mucus that don't drain normally
atelectasis collapsed lung, incomplete expansion of aveoli
Emphysema Hyperinflation of air sacs
Lung cancer malignant tumor arising from the lungs
pneumoconiosis Abnormal condition caused by dust in the lungs
Pneumonia acute inflammation and infection of alveoli
Pulmonary abscess large collection of pus
pulmonary edema fluid in the air sacs and bronchioles
pulmonary embolism clot or other materials lodges in vessels of the lung
pulmonary fibrosis formation of scar tissue
Tuberculosis Infectious disease but any organ in the body may be affected
pleurisy Inflammation of the pleura
Pneumothorax Collection of air in the pleural space
Hemothorax blood in pleural cavity
COPD Chronic Obstructive pulmonary disease
Pallitive relieving symptoms, but not curing the disease
Paroxysmal sudden occurrence, like spasm, seizure.
pulmonary infraction death of lung tissue
purulent containing pus
Chest X-ray (CXR) Radio-graphic image of the thoracic cavity
Computed tomography (CT) scan of chest computer generated series of x-ray images
(MRI) Magnetic resonance imaging Magnetic waves create detailed images of the chest
positron emission tomography (PET) scan of the lung Radioactive glucose in injected and images reveal
endotracheal intubation placement of a tube through the mouth into the pharynx, larynx, and trachea to make airways
Laryngoscopy Visual Examination of the voicebox
Lung biopsy Removal of lung tissue followed by microscopic examination
mediastinoscopy Endoscopic visual
Pulmonary function tests (PFTS) Tests that measure the ventilation mechanics of the lungs(airway function, lung volume, and the capacity of the lungs
thoracentesis Surgical puncture to remove fluid from the pleural space
Thoracotomy large surgical incision of the chest
Thoracoscopy Visual examination of the chest
Tracheostomy Surgical creation of an opening into the trachea through the neck
Tuberculin test past or present tuberculous infection based on a positive reaction
Tube thoracostomy a flexible plastic chest tube is passed into the pleural space through an opening in the chest
