Emphysema raises FRC; therefore, it increases or decreases compliance?
Between breaths, alveolar pressure is about equal to what?
Large fluctuations in O2 and CO2 are results of a larger or smaller FRC?
These muscles raise the top two ribs.
This is the volume of air that remains in the lungs after expiration.
Type I cells are composed of what type of epithelium?
Which is the outer layer of the pleura, i.e. it touches the rib cage?
alveolar pressure - pleural pressure =
Atmospheric pressure in Tucson is
Asbestosis causes the lung tissues to thicken or stiffen. This causes a decreased or increased compliance?
The right lung has how many lobes?
This depends on periodic pressure changes in the lungs.
The respiratory muscles, rib cage, pleural membranes and lung elastic tissues all comprise the what?
The left lung has how many lobes?
This is the measure of ease with which the lungs can be inflated.
At end inspiration, the diaphragm relaxes and elastic tissues in the lungs do what?
Respiratory bronchioles branch into
The internal intercostals and abdominal muscles are apart of which groups of respiratory muscles?
These muscles expand the rib cage by moving the ribs upward and out.
This type of respiration refers to the exchange of gases between the atmosphere and the pulmonary circulation
The layer of the pleura that touches the lungs is which layer?
Atmospheric pressure at sea level is
The diaphragm, external intercostals, sternocleidomastoid and the scalenes are all apart of which groups of respiratory muscles?
dV/dP=
The respiratory zone starts at the
This structure separates the upper and lower parts of the respiratory system
QuestionAnswerExtra
The supply in which the lung capillaries receive deO2 blood from pulmonary arteries
The air that actually ventilates the alveoli (TV - dead space V) x breathing frequency [L/min]
This is the volume that is measured during the period between breaths.
FRC stands for:
When the pressure in the lungs becomes lower than atmospheric pressure, you:
End-Expiratory Lung Volume is also known as:
Atmospheric pressure in Denver is
When the pressure in the lungs is higher than atmospheric pressure, you:
Alveolar ducts lead into
What do Type II cells do?
This type of respiration refers to gas exchange between capillary oxygen and tissue cells
TV (L) x Breathing Frequency (breaths/min) [L/min]
Recoiling of the lungs raises or lowers alveolar pressure?
These muscles depress the lower ribs and move the diaphragm up and into the thorax.
These muscles pull the ribs down and inward in order to reduce the diameter of the rib cage.
This type of respiration refers to oxidation of glucose to produce ATP
The alternating flow of air into and out of the lungs
Labored breathing is the result of a larger or smaller FRC?
This muscle elevates the sternum.
This is the primary inspiratory muscle.
This is the volume that fresh air mixes with in order to increase lung oxygen stores, and decrease lung carbon dioxide stores.
Which process begins when the diaphragm contracts to enlarge the thoracic cage?
The measurement of the rate of air movement into the lungs (L/min or mL/sec)
An increase in pressure lowers or raises the intrepleural pressure?
The supply in which the lung tissues receive O2 blood from bronchial arteries.
The conducting zone ends at the
