RESPIRATORY
SYSTEM TERMS
- Body system that brings oxygen into the body and feeds to
cells via the blood.
- Upper respiratory tract
- nose, mouth, pharynx, epiglottis and larynx
- nose = naso or rhino
- pharynx = throat…..combining form is pharyngo
- larynx = combining form is laryngo
- Lower respiratory tract
- trachea, bronchi, bronchioles, alveoli
- trachea = combining form is tracheo
- bronchi = combining form is broncho
- alveoli = combining form is alveolo
- all located within the thorax….combining form is thoraco
- lung = combining form is pneumo or pulmono
- mediastinum = region between lungs that contains heart,
aorta, esophagus and lymph nodes (LN)
- pleura = membrane around lungs….combining form is pleuro
- diaphragm = muscle between thorax and abdomen (dia =
between, phragm = wall)
- diaphragmatic hernia – opening in diaphragm allowing
abdominal organs to enter the thoracic cavity.
- General terms
- apnea = not breathing
- dyspnea = difficult breathing
- hyperpnea = increased breathing
- hypopnea = decreased breathing
- hyperventilation = abnormal, rapid breathing
- hypoxia = decreased oxygen
- hypercapnia = increased CO 2 (carbon dioxide) in the
blood
- phlegm = thick mucus secreted by respiratory tract
- Diagnostic terms
- auscultation = listening to body sounds using a
stethoscope
- bronchoscopy = procedure to visually examine the bronchi
- laryngoscope = an instrument used to visually examine the
larynx….usually for intubation.
- thoracentesis = to withdraw fluid from the chest or
thorax
- tracheal wash = flushing and retrieving a small amount of
fluid into the trachea to analyze the contents (culture, cytology, etc.)
- Pathology terms
- anoxia = without oxygen
- asphyxiation = interruption of breathing resulting in
hypoxia
- aspiration = inhalation of a foreign substance into the
upper respiratory tract.
- asthma = chronic allergic disorder
- atelectasis = collapse of the lungs
- bronchitis = inflammation of the bronchi
- bronchopneumonia = abnormal condition of the bronchi and
lungs
- COPD = chronic obstructive pulmonary disease
a. usually
results of hardening of respiratory tract
b. horses
with “heaves”
- cyanosis = blue coloration of MM (mucus membranes) due to
decrease oxygen.
- emphysema = chronic lung disease caused by increased size
of alveoli…..resulting in poor oxygen exchange.
- epistaxis = nosebleed
- hemothorax = blood in chest
- laryngitis = inflammation of the larynx
- pharyngitis = inflammation of the pharynx (sore throat)
- pleurisy or pleuritis = inflammation of the lining around
the lungs
- pneumonia = abnormal condition of the lung
- pneumothorax = abnormal air in the thoracic cavity which
collapses a lung
- pulmonary edema = accumulation of fluid in the lungs
- pyothorax = pus in the chest
- exudates = fluid discharge from an area
- rhinitis = inflammation of the nose
- rhinopneumonitis = inflammation of the nose and lungs
- snuffles = upper respiratory infection of rabbits
- stenotic nares = narrowed nostrils
- tracheitis = inflammation of the trachea
- tracheobronchitis = inflammation of the trachea and
bronchi (kennel cough)
- Procedures and Drugs
- bronchodilators = drugs that increase the lumen of the
bronchi
- antitussives = drugs that control coughing
- endotracheal intubation = to place a tube into the
trachea for breathing ,,,,,,,usually for an anesthetic procedure.
- lobectomy = removing a part (lobe) of a lung
- pharyngostomy = surgical creation of an opening into the
throat
a. used
to place a feeding tube to force feed an animal
- thoracotomy = incision into the chest (thorax)
- tracheotomy = incision into the trachea
