T/F: Gas exchange ocurrs in the conducting airways.
Is the airflow in the respiratory or alveolar airways laminar or turbulent?
If the transpulmonary pressure is +3, then the lungs are ____ (collapsing or expanding).
site of gas exchange in the lung
Volume of air in lungs remaining after maximal expiration
T/F: During inspiration, the transpleural pressure difference becomes greater and allows for expansion of the lungs and alveoli.
patients with pulmonary fibrosis have a ___ lung recoil
Which component of Fick's Law can be manipulated in the clincial setting?
Normal Tidal Volume in liters
Lung recoils is used during ____.
Principal(or Law) that provides the basis for airflow in the lung
T/F: The terminal bronchioles are surrounded by smooth muscle
Maximal Volume that can be exhaled at the end of a tidal volume
given change in lung volume per given changes in pleural pressure
True or False: The rate of diffusion is proportional to the area of the membrane and inversely proportional to it thickness
Volume of air than can be inhaled at the end of a normal breath
As the diaphragm contracts. the volume increases in the pleural space. What happens to the pleural pressure?
Gas moves across the alveoli via _____ diffusion
T/F: During inspiration, the pressure in the alveolus become sub-atmospheric, allowing air from the atmosphere to move into the lungs.
patients with emphysema have a ____ lung compliance
Which gas is the first to be affected by a diffusion limited disorder?
Essential muscle in creating differences in transpleural pressure
On average, how much time does an RBC spend in the respiratory airways (sec)?
Volume of air that can be exhaled as forcibly and rapidly as possible from total lung capacity
Volume of air that can be exhaled after normal expiration (=total lung capacity - residual volume)
pressure in the pleural cavity is normally ____ cm H2O at the end of a tidal volume breath
T/F: An increase in particle size increases rate of diffusion
Work during breath occurs on ____.
Where is the majority of the surface area of the lung located?
The internal intercostals and the abdominal muscle are important for ____.
T/F:An Increase in molecule solubility increases rate of diffusion
most important muscle for inspiration
Maximal volume of air that can be inhaled after normal expiration (=tidal volume +IRV)
units for measurement of transpulmonary pressure
T/F: A 'diffusion limited' A-a gradient is smaller than under normal circumstances.
Is the airflow in the conducting airways laminar or turbulent?
Function of these airways is to clean, condition, and warm air
low partial pressure of oxygen in tissues
inversely proportional to lung compliance
Has Z numbers spanning from Z17-Z23
Has a Z number that spans from Z0-Z16

Z number or generation number for the trachea
Volume of air in the conducting airways (mL)
Volume of air in the respiratory or alveolar airways (mL)
pressure in the atmosphere is ___ cm h20
A ____ in surface area and a _____in membrane thickness can cause the lung to become diffusion limited.
2 main forces that must be overcome during breathing?
The diaphragm, the external intercostals, and the sternocleidomastoids are important for _____.
These bronchi are the site of highest resistance to airflow and are surrounded by smooth muscle
