inflammation of the lungs caused by inhaling or choking on vomitus


a chronic allergic disorder characterized by episodes of severe breathing difficulty, coughing, and wheezing


Collapsed lung; incomplete expansion of alveoli


abnormally slow rate of respiration usually of less than 10 breaths per minute


a drug that relaxes and dilates the bronchial passageways and improves the passages of air into the lungs


an excessive discharge of mucus from the bronchi


use of a flexible endoscope, called a bronchoscope, to examine the airways


a spasm of the bronchi that makes exhalation difficult and noisy

cheyne-stokes respiration

pattern of breathing characterized by a gradual increase of depth and sometimes rate to a maximum level, followed by a decrease, resulting in apnea


an acute respiratory syndrome in children and infants characterized by obstruction of the larynx, hoarseness, and a barking cough

cystic fibrosis

a genetic disorder in which the lungs and pancreas are clogged with large quantities of abnormally thick mucus


an acute bacterial infection of the throat and upper respiratory tract


difficulty producing speech sounds, usually due to hoarseness


difficult or labored respiration


disease in which the tissues of the lungs lose elasticity, making breathing very difficult


a collection of pus in a body cavity (especially in the lung cavity)

endotracheal intubation

the passage of a tube through the nose or mouth into the trachea to establish or maintain an open airway


bleeding from the nose


coughing up blood


accumulation of blood in the pleural cavity (the space between the lungs and the walls of the chest)


the presence of an abnormally high level of carbon dioxide in the circulating blood


energetic (deep and rapid) respiration that occurs normally after exercise or abnormally with fever or various disorders


abnormally slow or shallow respirations


deficient amount of oxygen in the blood


a very strong drive resulting from a deficiency of available oxygen in the blood and bodily tissues (short of anoxia)


surgical removal of part or all of the larynx (usually to treat cancer of the larynx)


inflammation of the larynx


paralysis of the vocal cords and larynx


visual examination of the larynx to detect tumors, foreign bodies, nerve or structural injury, or other abnormalities


the part of the thoracic cavity between the lungs that contains the heart and aorta and esophagus and trachea and thymus


pumps air or oxygen through a liquid medicine to turn it into a vapor, which is then inhaled by the patient via a face mask or mouthpiece


a physician with specialized training in the diagnosis and treatment of diseases and disorders of the ears, nose, throat, and related structures of the head and neck; also known as an ENT


whooping cough; highly contagious bacterial infection of the pharynx, larynx, and trachea caused by Bordetella pertussis


Inflammation of the pharynx; also known as a sore throat.


surgical repair of the pharynx


surgical removal of part of the pleura


inflammation of the pleura that produces sharp chest pain with each breath


pain in the pleura or in the side that occurs in relation to breathing movements


abnormal condition caused by dust in the lungs, with chronic inflammation, infection, and bronchitis


surgical removal of a lung (usually to treat lung cancer)


air in the pleural cavity caused by a puncture of the lung or chest wall


monitoring and recording of normal and abnormal activity during sleep to diagnose sleep disorders


A physician who specializes in the diseases and disorders of the lungs and respiratory system

pulse oximeter

a device that measures the oxygen saturation of arterial blood by reference to light wave lengths


Pus in the chest cavity


inflammation of the sinuses


an abnormally rapid rate of respiration, usually >20 breaths per minute


surgical puncture of the thoracic cavity, usually using a needle, to remove fluids


the surgical creation of an opening into the chest cavity to establish drainage of empyema


surgical creation of an opening into the trachea through the neck


an emergency procedure in which an incision is made into the trachea to gain access to the airway below a blockage


An infectious disease caused by mycobacterium tuberculosis which affects the lungs but can also spread to other parts of the body.

upper respiratory tract consists of

the nose, mouth, pharynx, epiglottis, larynx, and trachea

lower respiratory tract consists of

the bronchial tree and lungs. These structures are located within, and protected by, the thoracic cavity which is also known as the rib cage

nasal cavity

interior portion of the nose

nasal septum

is a wall of cartilage that divides the nose into two equal sections. A septum is a wall that separates two chambers


thin hairs located just inside the nostrils, filter incoming air to remove debris

Mucous membranes

are the specialized tissues that line the respiratory, digestive, reproductive, and urinary systems


which is secreted by the mucous membranes, protects and lubricates these tissues. In the
nose mucus helps to moisten, warm, and filter the air as it enters. Notice the different spellings; however, they have the same pronunciation. Mucous is the name of
the tissue; mucus is the secretion that flows from the tissue.

olfactory receptors

are nerve endings that act as the receptors for the sense of smell. They are also important to the sense of taste. These receptors are located in the mucous membrane in the
upper part of the nasal cavity


form a protective circle of lymphatic tissue
around the entrance to the respiratory system

paranasal sinuses

air-filled cavities lined with mucous membrane, are located in the bones of the skull. These sinuses are connected to the nasal cavity via short ducts (para- means near, nas means nose, and -al means pertaining to).


which is commonly known as the throat, receives the air after it passes through the nose. The pharynx is made up of three divisions

frontal sinuses

located in the frontal bone just above the eyebrows. An infection here can cause severe
pain in this area.

sphenoid sinuses

which are located in the sphenoid bone, are close to the optic nerves and an
infection here can damage vision

maxillary sinuses

which are the largest of the paranasal sinuses, are located in the maxillary bones. An infection in these sinuses can cause pain in the
posterior maxillary teeth

ethmoid sinuses

which are located in the ethmoid bones, are irregularly shaped air cells that are separated
from the orbital (eye) cavity by only a thin layer of bone


is a lid-like structure located at the base of the tongue,
swings downward and closes off the laryngopharynx so
that food does not enter the trachea and the lungs.
