Respiratory Terminology

pressure of a gas is inversely related to the volume of a gas

• each gas contributes its percentage of atmospheric pressure
• pressure of a gas is known as the partial pressure

chemical produced by RBCs which causes oxygen to release from hemoglobin

inability to detect odors

deficiency of oxygen

to stop breathing

pressure exerted by gases in the air

• part of the respiratory tract that has no cartilage and serves the lobules of the lung
• its spasms cause asthma

• odorless, colorless gas from incomplete combustion
• competes with oxygen at the hemes

movement of chlorine ions in/out of the RBC as bicarbonate ions move out/in

respiratory mechanism to clear obstructions from the airways

• condition characterized by a loss of elasticity of the lungs
• walls of the alveoli break down and are replaced by larger air sacs

normal quiet breathing

forcing of air out of the lungs due to positive pressure

iron containing part of hemoglobin where oxygen and carbon dioxide attach

coughing and spitting of blood as a result of bleeding within the respiratory tract

spasmodic contraction of the diaphragm resulting from stimulation in the diaphragm or in the respiratory center of the brain

point of attachment of vessels to the lungs

animals that maintain a constant body temperature

• increase in breathing rate due to exercise
• increased body temperature or emotional stress

elevated or high body temperature (fever)

• region of the brain which controls the temperature of endothermic animals
• its sensors detect changes in the temperature of the circulating blood and initiate the appropriate responses

state of having too little oxygen in the tissures for normal metabolism

movement of air into the lungs due to negative pressure

inflammation of the vocal cords

cavity that includes everything in the thoracic cavity except the lungs

lower than the surrounding atmospheric pressure

• air containing spaces lined with mucous membranes and open to the nasal cavity via ducts
• includes maxillary, frontal, sphenoid, ethmoid sinuses

exerted by a specific gas in the atmosphere

membranes of the lungs and lung cavity

inflammation of the pleural membranes

membrane that lines the inside of the pleural cavity wall and covers the diaphragm

any lung condition in which the alveoli become filled with fluid or blood

• animals whose body temperature changes with atmospheric temperature
• ex: reptiles, amphibians, fish

lungs

substances that cause fever by resetting the thermostat in the hypothalamus

condition in which fluid accumulated in the alveoli and interstitial spaces of the lungs

membrane which covers the lungs

breathing

2 squamous cell layers between the alveolar and capillary walls

inflammation of the membranes of the paranasal sinuses

• forcible exhalation of air through the nasal passageways
• upper respiratory cough

opening in the trachea

procedure in which the trachea is brought to the skin or a tube is placed in ot keep it open for a periond of time
