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