Flashcards in 16 - The Respiratory System Deck (57)
Small sacs in the lungs that fill with air from the alveolar ducts (singular alveolus).
The larger air passages in the lungs.
A tiny branch of the bronchi that connects to the alveoli.
The outer curved part of the nasal cavities that acts as a filter for dust, and to warm and moisten the incoming air.
A dome-shaped muscle between the thoracic and abdominal cavities; controls regular, relaxed breathing by contracting and relaxing.
A cartilaginous flap above the glottis that closes while food or liquid is passing through the pharynx.
Another term for exhalation (breathing out).
The vocal cords and the opening between them.
Another term for inhalation (breathing in).
The bottom part of the pharynx.
The voice box
The main breathing organs in the chest that bring oxygen into the body and expel carbon dioxide.
Any of the passages in the nasal passages.
The part of the pharynx behind the nasal cavity and above the soft palate.
External openings of the nose that provide air passage and secretions from the nose and eyes.
The part of the throat located at the back of the mouth.
The outer layer of the pleural membrane.
The cavity at the back of the mouth that opens to the esophagus and larynx.
The volume of air left in the lungs after a maximum exhalation.
An air-filled cavity
The volume of air that is inhaled or exhaled during a normal, resting breathing cycle.
The volume of air in the lungs after a maximum inhalation.
Total lung capacity
The inner layer of the pleural membrane
The volume of gas that can be exhaled from the lungs at maximum inhalation.
A number of conditions in which the lungs receive inadequate oxygen; may be caused by a pathological condition or by exposure to smoke, pollution, or toxic chemicals, resulting in shortness of breath.
Acute respiratory disease syndrome (ARDS)
The temporary cessation of breathing (usually occurs during sleep)
A condition caused by an inadequate intake of oxygen.
The accidental inhalation of foreign matter into the bronchial system.
A disease characterized by narrowing of the bronchial tubes, making breathing difficult.
Abnormally slow breathing
Inflammation of the bronchi
An irregular breathing pattern consisting of periods of maximum respiration followed by a progressive decrease until apnea results; often seen in comatose or brain-injured patients.
A progressive disease characterized by shortness of breath, wheezing, and chronic coughing, usually caused by smoking; usually a combination of chronic bronchitis and emphysema.
Chronic obstructive pulmonary disease (COPD)
Profuse discharge from the mucous membrane of the nose.
A common genetic disorder of infants and children in which thick, viscous mucus is produced in the respiratory tract; the exocrine glands do not secrete properly, and a predisposition to bacterial infections exists in the lungs.
Shortness of breath
A lung disease in which tissue deterioration results in increased air retention and reduced exchange of gases. The result is difficulty breathing and shortness of breath; usually caused by smoking.
A common nosebleed
A seasonal rhinitis resulting from an allergic reaction to pollen.
Coughing up blood from lungs or airways
An involuntary spastic contraction of the diaphragm.
Abnormally deep or fast respiration, in which excessive quantities of air are taken in, causing buzzing in the ears, tingling in the extremities, and sometimes fainting.
An acute viral infection involving the respiration tract and other body systems.
A cancerous growth in the lung tissue.
An inflammation of the covering around the lungs.
An inflammation of the lungs caused by a bacterial or viral infection, which causes fever, shortness of breath, and the coughing up of phlegm (mucus and other material produced by the lining of the respiratory tract; also called sputum).
A collapsed lung caused by accumulation of air or gas in the space between the lung and chest wall.
The abnormal collection of fluid in the lungs.
An inability of the lungs to conduct gas exchange.
Asthma, hay fever, and other conditions caused by oversensitivity of any part of the respiratory system.
A failure to provide adequate oxygen to the cells of the body and remove carbon dioxide.
An inflammation of mucous membranes in the nose; the common cold.
Pain or discomfort from inflammation of any combination of the tonsils, larynx, or pharynx; also called pharyngitis.
Exaggeratedly rapid breathing
