components of the lungs
what feature of the cells lining the respiratory passageways enables them to move impurities away from the lungs?
cilia
in what structure does gas exchange occur in the lung?
alveoli
what are the two phases of quite breathing?
inspiration and exhalation
what is the name of the membrane that encloses the lung?
the pleura
which phase of breathing is active and which is passive?
active: inspiration
passive: exhalation
what gas is the main chemical controller of respiration?
Co2
what substance in red blood cells holds almost all the oxygen carried in the blood?
hemoglobin
what is the first phase of breathing?
inhalation
where is the pleural space located?
within the thoracic cavity (between the visceral(inner) pleura and parietal (outer) pleura)
what is described as the amount of air that can be inhaled and exhaled with the deepest possible breath?
vital capacity
what purpose does mucus in the nasal cavity serve?
traps smaller particles like pollen or smoke to protect to the lungs
what is the main form in which CO2 is carried in the blood?
bicarbonate
what is the second phase of breathing?
expiration
which substance normally exists in the pleural cavity?
small amount of serous fluid
restlessness, and anxiety
list the upper respiratory structures
nasal cavity, pharynx, larynx, oral cavity, trachea, esophagus,
why does the alveoli contain small amounts of fluid?
to facilitate gas exchange by providing a medium for oxygen and carbon dioxide to dissolve and diffuse across the alveolar membrane into the bloodstream
what is hyperventilation?
a pattern of rapid and deep breathing
the left lung has how many lobes?
2 lobes
what is the structure involved in opening between the vocal cords?
glottis
which structure is the opening on the lung's medial surface through which primary bronchi and pulmonary blood vessels pass?
hilum
what is described as the pressure between the visceral and parietal pleurae, which assists with lung expansion?
intra-pleural pressure
what is the structure that is known as the voice box?
larynx
what is the bony structure separating the mouth from the nasal cavity?
palate
