Chapter Twelve- Respiratory Flashcards
Alveolus
Air sac in the lung
Apex of the lung
Tip or uppermost portion of the lung
Base of the lung
Lower portion of the lung
Bronchioles
Smallest branches of the bronchi
Bronchus
Branch of the trachea that is a passageway into the lung; bronchial tube
CO2
Gas produced by body cells when oxygen and food combine; exhaled through lungs
Cilia
Thin hairs attached to the mucous membrane epithelium lining the respiratory tract
Diaphragm
Muscle separating the chest and abdomen; makes breathing possible
Epiglottis
Lid-like piece of cartilage that covers the larynx, preventing food from entering when swallowing
Expiration
Breathing out
Glottis
Slit opening to the larynx
Hilum
Midline region where the bronchi, blood vessels, and nerves enter and exit the lungs
Inspiration
Inhaling
Larynx
Voice box
Lobe
Division of a lung
Mediastinum
Region between the lungs in the chest cavity; contains trachea, heart, aorta, esophagus, and bronchial tubes
Nares
Openings through the nose carrying air into the nasal cavities
O2
Gas that passes into the bloodstream at the lungs and travels to all body cells
Palatine sinus
One of a pair of almond shaped masses of lymphatic tissue in the oropharynx
Paranasal sinus
One of the air cavities in the bones near the nose
Parietal pleura
Outer fold of pleura lying closer to the ribs and chest wall
Pharynx
Throat
Pleura
Double folded membrane surrounding each lung
Pleural cavity
Space between the folds of the pleura
Pulmonary parenchyma
Essential parts of the lung; bronchioles and alveoli
Respiration
Breathing
Trachea
Windpipe
Visceral pleura
Inner fold of pleura lying closer to the lung tissue

-thorax
Pleural cavity, chest
Chest X-ray (CXR)
Radiographic image of the thoracic cavity (chest film)
Computed tomography scan of the chest
Computer generated series of X-ray images show thoracic structures in cross section and other planes
Magnetic resonance imaging of the chest (MRI)
Magnetic waves create detailed images of the chest in frontal lateral and cross-sectional planes
Positron emission tomography (PET) scan of the lung
Radioactive glucose is injected and images reveal metabolic activity in the lungs
Ventilation-perfusion (V/Q) scan
Detection device records radio activity in the lung after injection of a radio isotope or inhalation of small amount of radioactive gas (xenon)
Bronchoscopy
Fiberoptic endoscope examination of the bronchial tubes
Endotracheal intubation
Placement of a tube through the mouth into the pharynx, larynx, and trachea to establish an airway
Laryngoscopy
Visual examination of the voicebox
Lung biopsy
Removal of lung tissue followed by microscopic examination
Mediastinoscopy
Endoscopic visual examination of the mediastinum
Pulmonary function tests (PFTs)
Tests that measure the ventilation mechanics of the lungs; i.e., airway function, lung capacity, lung volume, and capacity of the lungs to exchange oxygen and carbon dioxide efficiently
Thoracentesis
Surgical puncture to remove fluid from the pleural space
Thoracotomy
Large surgical incision of the chest
Thoracoscopy (thorascopy)
Visual examination of the chest via small incisions and use of an endoscope
Tracheostomy
Surgical creation of an opening into the trachea through the neck
Tuberculin test
Determines past or present tuberculous infection based on a positive skin reaction
Tube thoracostomy
Chest tube is passed through an opening in the chest to continuously drain a pleural effusion
