Respiratory System Terms
Flashcard maker : Deacon Kirby
space (separates) between vocal cords.
Upper Respiratory Infection- infection of nose, larynx & bronchi ex. Colds caused by a virus.
Inflammation of the pharynx- symptoms: sore throat & difficulty in swallowing.
Hoarseness; inflammation of the “voice box” or larynx
Inflammation of the nasal mucosa
inflammation of air cavities (spaces)
Instrument used for visual examination within a hollow organ or body cavity.
an inflammation of lungs caused by Tubercle Bacillus, a bacteria known as “myobacterium tuberculosis”
an absence of spontaneous respiration. ex. obstructive sleep apnea- repetitive pharyngeal collapse during sleep which leads to absence of breathing (pharynx-throat)
inflammation of bronchi
fluid accumulation of the alveoli & brochioles
operation of inserting a metal tube in the trachea
lack of oxygen
condition of characterized by obstruction of bronchial tubes & dyspnea
labored or difficulty breathing
the portion of the brain that controls the respiratory center
highly infectious disease caused by a virus
bluish color of skin
stretching of lung tissue, caused by alvelor becoming so distended and loosing elasticity
suffocation, lack of tissue O2 accompanied by increase in tissue CO2
to withdraw fluid or to suction, to draw foreign material into respiratory tract
instrument used to remove mucus & other substances from the respiratory tract
foreign matter, such as blood clot, air, or fat carried in the circulation to pulmonary artery where it acts as a block
nerve that supplies the diaphragm
hereditary disease, characterized by excessive mucous in respiratory tract
“voice box” located just below the pharynx
removal of a lung
scientific name for the throat
URI caused by a virus- “flu”
the etiologic agent that causes a cold or flu
iron containing protein that carries O2 in the blood
small air sacs
leaf shaped, cartilage, partially covers the opening of the larynx. The epiglottis acts like a trapdoor, closing off the larynx during swallowing and preventing food from entering the trachea.
a condition in which the nasal septum strays from the midline of the nasal cavity. sometimes congenital defect or results of injury or infection. may be surgically repaired
instrument used for visual exam within a hollow organ or body cavity
instrument used to examine larynx (voice box) or to help insert intubation tube.
instrument used to measure breathing (or lung volume). in other words it is used to measure volumes of air exchanged in breathing
cycles of alternating apnea & dyspnea associated with critical conditions
failure to resume breathing after a period of apnea
rapid & deep respiration
slow & shallow respirations
deficient (lack of) O2 tissue
ability to breathe only in an upright position
coryzna or rhinorrhea
discharge from the nose (as in a cold)
region of the brain that contains respiration control center
amount normally breathed in or out with each breath (relaxed breathing)
the largest amount of air that one can breathe out in one expiration
expiratory reserve volume (ERV)
amount of air that can be forcibly exhaled after expring the tidal volume
inspiratory reserve volume (IRV)
amount of air that can be forcible inhaled after a normal inspiration
residual volume (RV)
air that remains in the lungs after the most forceful expiration
usually about 12-18 breaths a minute; much faster during exercise
a substance manufactured by special cells in the walls of the alveoli. it reduces the surface tension to prevent alveoli from collapsing (this important substance is not fully developed until shortly before birth- normally about 40wks after conception)
the creation of an artificial opening into the trachea in which a tube is usually inserted.
inscision into the trachea
air in the chest (peural space) which causes collapse of the lung
fluid accumulation in the alveoli & bronchioles
is an inflammation of the parietal pleura, characterized by difficulty in breathing and stabbing pain
collapse of the lung for any reason is called atelectasis ex. pneumothorax- “air in the thorax” is the presence of air in the pleural space on one side of the chest from ex. a puncture wound to the chest wall or a rupture of the visceral pleura.
the presence of “blood in the pleural space” both potentially life threatening unless medical treatment is received
small cavities in the bones of the skull are lined with mucus membrane
separates the thoracic cavity from the abdominal cavity. dome shaped muscle- flattens during inhalation.
the nerve that stimulates the diaphragm
chronic bacillus infection caused by “myobacterium tuberculosis”. highly contagious transmitted through inhalation or swallowing of droplets contaminated with TB bacillus.
a membrane around the lungs
the part of the pleura attached to the lung (closest to the organ)
the part of the pleura attatched to the lung (closest to the organ)
the part of the pleura attached to the chest wall
a reduced supply of oxygen to the tissues
the heart is situated in this space between the lungs
the physical process by which gasses are exchanged in the body
a depression on the medial side of the lung where bronchus enters
the smallest division of the bronchus
