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