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