How to Play
Volume of air than can be inhaled at the end of a normal breath
units for measurement of transpulmonary pressure
T/F: An increase in particle size increases rate of diffusion
T/F: During inspiration, the pressure in the alveolus become sub-atmospheric, allowing air from the atmosphere to move into the lungs.
2 main forces that must be overcome during breathing?
Maximal volume of air that can be inhaled after normal expiration (=tidal volume +IRV)
pressure difference between the alveoli and the pleural space is known as ____ ____.
Total volume of air in lungs after maximal inspiration
Volume of air in lungs remaining after maximal expiration
Maximal Volume that can be exhaled at the end of a tidal volume
On average, how much time does an RBC spend in the respiratory airways (sec)?
Lung recoils is used during ____.
Volume of air in the conducting airways (mL)
patients with pulmonary fibrosis have a ___ lung recoil
Volume of air remaining in the lungs after a normal expiration
Normal Tidal Volume in liters
T/F: A 'diffusion limited' A-a gradient is smaller than under normal circumstances.
Has a Z number that spans from Z0-Z16
low partial pressure of oxygen in tissues
most important muscle for inspiration
inversely proportional to lung compliance
Volume of air that can be exhaled as forcibly and rapidly as possible from total lung capacity
The internal intercostals and the abdominal muscle are important for ____.
Where is the majority of the surface area of the lung located?
True or False: The rate of diffusion is proportional to the area of the membrane and inversely proportional to it thickness
Z number or generation number for the trachea
Volume of air in the respiratory or alveolar airways (mL)
Gas moves across the alveoli via _____ diffusion
Work during breath occurs on ____.
As the diaphragm contracts. the volume increases in the pleural space. What happens to the pleural pressure?
Volume of exhaled air with every breath is known as ____ volume.
Volume of air that can be exhaled after normal expiration (=total lung capacity - residual volume)
patients with emphysema have a ____ lung compliance
T/F: During inspiration, the transpleural pressure difference becomes greater and allows for expansion of the lungs and alveoli.
site of gas exchange in the lung

Has Z numbers spanning from Z17-Z23
Is the airflow in the conducting airways laminar or turbulent?
given change in lung volume per given changes in pleural pressure
T/F:An Increase in molecule solubility increases rate of diffusion
pressure in the pleural cavity is normally ____ cm H2O at the end of a tidal volume breath
pressure in the atmosphere is ___ cm h20
T/F: Gas exchange ocurrs in the conducting airways.
The diaphragm, the external intercostals, and the sternocleidomastoids are important for _____.
Principal(or Law) that provides the basis for airflow in the lung
low partial pressure of oxygen in blood
Which gas is the first to be affected by a diffusion limited disorder?
