100
The major mucles of the respiratory system (looking for at least 2)
What are disphragm, intercostal and accessory
100
Moistens and filters inspired air
What is the nose
100
Active process (requires energy) that happens when thoracic pressure dalls below atmospheric pressure
What is inspiration
100
The amount of air moved into or out of the lungs in a single breath is referred to as
What is tidal volume (TV) (average is 500 mL for the adult male)
100
A respiratory rate over 20 per minute
What is Tachypnea
200
Four of the upper airway structures
What are nose, mouth, jaw, pharynx, larynx, epiglottis
200
Passageway for air, food and drink
What is the pharynx (Naso or oro)
200

Found in the brainstem and arteries, these monitor pH, oxygen and carbon dioxide levels

What are chemoreceptors

200
The portion of the tidal volume that does not reach the alveoli and thus does not participate in gas exchange
What is dead space (approximately 150 mL)
200
A respiratory rate less than 12 per minute
What is Bradypnea
300
Name the four structures of the lower airway
What are trachea, main bronchi, bronchioles, and alveoli
300
Prevents food and drink from entering airway when swallowing
What is the epiglottis
300
The "backup sytem" that controls respiration
What is the hypoxic drive
300
The amount of air moved into and out of the lungs in 1 minute minus the dead space
What is Minute Ventilation (or Volume) (MV). This is TV (- dead space) x RR.
300
Condition where the cells of the body are not receiving enough oxygen
What is Hypoxia
400
Forms the most inferior portion of the larynx and and is the only completely circular cartilaginous ring of the upper airway
What is the cricoid cartilage
400
The site of gas exchange
What is aveoli
400
The two main portions of the medulla that control breathing
What are the dorsal respiratory group (the DRG) and the ventral respiratory group (VRG)
400
The air that remains after maximal expiration
What is residual volume (about 1200 mL in the average adult male)
400
Increased carbon dioxide levels in the blood
What is hypercarbia
500
Point at which the trachea splits into the right and left mainstem bronchi
What is the carina
500
Lines the chest wall and both lungs to allow the lungs to expand or conract with the chest wall
What is the pleura (visceral and parietal)
500
The reflex that prevents you from taking too deep a breath
What is the Hering-Breuer reflex
500
The amount of air that reaches the alveoli
What is Alveolar Ventilation (tidal volume (TV) - Dead space)
500
The ability of the alveoli to expand when air is drawn in during inhalation
What is compliance
