Terms of Respiration
The volume of air inspired or expired during the breathing cycle.
What is tidal volume (TV)?
The anatomical structure that is superior to the main-stem bronchi.
What is the trachea?
This structure is the primary muscle of respiration and contracts to increase the volume of the thoracic cavity.
What is the diaphragm?
When this inspiratory muscle contracts, it flattens and moves downward, essentially increasing thoracic cavity volume.
What is the diaphragm?
This phase of breating involves active contraction of the respiratory muscles to push air into the lungs.
What is inspiration?
The maximum volume of air hat can be expired following a maximum expiration.
What is vital capacity (VC)?
Left superior lobe, right superior lobe, middle lobe, left inferior lobe, and right inferior lobe
What are the five lobes of the lungs?
These paired organs hold the air supply needed for speech and are responsible for generating subglottal pressure.
What are the lungs?
These stomach muscles squeeze inward during forced exhalation to push air out of the lungs.
Law that describes how pressure decreases within the lungs during inspiration.
What is Boyle's Law?
The volume of air in the pulmonary apparatus
after a maximum inspiration
What is total lung capacity?
The letter that represents the shape of the rings in the trachea.
These muscles work with the diaphragm during inspiration to expand the rib cage.
What are the external intercostals?
The primary muscles for inspiration
What are the external intercostal muscles?
The percentage of exhalation during life breathing
What is 60% exhalation?
The maximum volume of air that can be inspired from the peak of the tidal volume cycle.
What is inspiratory reserve volume (IRV)?
This is the air contining, air conduction, and gas exchanging part of the respiratory system.
What is the pulmonary apparatus.
This type of breathing happens automatically and supports life without conscious control.
What is quiet (tidal) breathing?
The muscles that depress the ribs during expiration.
What are the internal intercostal muscles?
During this part of the respiratory cycle, air flows out of the lungs because the thoracic cavity gets smaller and pressure inside the lungs increases.
What is expiration (exhalation)?
The volume of air in the pulmonary apparatus at the resting tidal end-expiratory level.
What is functional residual capacity (FRC)?
This structure contains the vocal filds and plays an important role in respiration and phonation.
What is the larynx?
This type of breathing recruits additional muscles, such as internal intercostals and abdominals, to allow longer utterances or louder speech.
What is forced breathing (speech breathing)?
These neck muscles help lift the upper ribs and sternum when you take a really deep breath.
What are the sternocleidomastoids?
This term describes the amount of air left in the lungs after a maximum exhalation, preventing the lungs from collapsing completely.
What is residual volume?
