The Respiratory System Flashcards
A small angular cavity or pit, such as a tooth socket or an air sac.
Alveoli
Are the tiny end ducts of the branching airways that fill the lungs.
Alveolar ducts
One of the small bilateral structures, attached to a small branch of the aorta near its arch.
Aortic body
Temporary absence or cessation of breathing.
Apnea
The plural of bronchus, either of the two main branches of the trachea.
Bronchi
A small branch of a bronchus.
Bronchioles
A compound of carbon dioxide and hemoglobin, which is one of the forms in which carbon dioxide exists in the blood.
Carbaminohemoglobin
A small epithelioid structure, located just above the bifurcation of the common carotid artery. Also called intercarotid body .
Carotid body
Any of various structures, such as the external ear, that resemble a shell in shape.
Conchae
Difficult or labored breathing.
Dyspnea
Easy, free respiration, as is observed normally under resting conditions.
Eupnea
The maximal volume of air, usually about 1000 milliliters, that can be expelled from the lungs after normal expiration. Also called reserve air , supplemental air .
Expiratory reserve volume (ERV)
The exchange of respiratory gases in the lungs.
External respiration
The technique employs a firm upward thrust just below the rib cage to force air from the lungs up through the trachea, thus dislodging the obstruction.
Heimlich maneuver
Abnormally fast or deep respiration .
Hyperventilation
Reduced or deficient ventilation of the lungs.
Hypoventilation
The maximal volume of air that can be inhaled after a normal inspiration. Also called complemental air .
Inspiratory reserve volume (IRV)
Process that take place in the cells and tissues during which energy is released and carbon dioxide is produced and absorbed by the blood to be transported to the lungs
Internal respiration
The region in between the pleural sacs, containing the heart and all of the thoracic viscera except the lungs. Also called mediastinal space .
Interpleural space
The part of the respiratory tract between the pharynx and the trachea.
Larynx
Inflammation of the larynx.
Laryngitis
Hemoglobin in combination with oxygen, present in arterial blood. Also called oxygenated hemoglobin .
Oxyhemoglobin
Sinus that is behind your nose and cheeks.
Paranasal sinuses
The upper section of the alimentary canal that extends from the mouth and nasal cavities to the larynx.
Pharynx
The part of the pharynx above the soft palate that is continuous with the nasal passages. Also called epipharynx .
nasopharynx
The pharynx between the soft palate and the epiglottis.
oropharynx
The part of the pharynx that lies below the aperture of the larynx and behind the larynx and that extends to the esophagus. Also called hypopharynx .
laryngopharynx
The thin serous membrane that envelops each lung and folds back to make a lining for the chest cavity.
Pleura
Pleura that lines the inner chest walls and covers the diaphragm
parietal pleura
Pleura that covers the lungs
visceral pleura
An inflammation of the pleura.
Pleurisy
The total volume of gas per minute inspired or expired.
Pulmonary ventilation
The volume of air remaining in the lungs after a maximal expiratory effort. Also called residual air , residual capacity .
Residual volume (RV)
The act or process of inhaling and exhaling; breathing. Also called ventilation .
Respiration
Is the cessation of normal respiration due to failure of the lungs to contract effectively.
Respiratory arrest
The membrane separating air within the alveoli from the blood within pulmonary capillaries.
Respiratory membrane
The mucous membrane lining the respiratory tract.
Respiratory mucosa
An instrument for determining the capacity of the lungs.
Spirometer
A substance composed of lipoprotein that is secreted by the alveolar cells of the lung and serves to maintain the stability of pulmonary tissue by reducing the surface tension of fluids that coat the lung.
Surfactant
It is composed of thin incomplete rings of hyaline cartilage connected by a membrane called the annular ligament. Also called windpipe .
