Has a Z number that spans from Z0-Z16
Volume of air remaining in the lungs after a normal expiration
A ____ in surface area and a _____in membrane thickness can cause the lung to become diffusion limited.
Volume of air in lungs after maximal inspiration
Is the airflow in the respiratory or alveolar airways laminar or turbulent?
pressure in the atmosphere is ___ cm h20
pressure difference between the alveoli and the pleural space is known as ____ ____.
T/F: A 'diffusion limited' A-a gradient is smaller than under normal circumstances.
The internal intercostals and the abdominal muscle are important for ____.
Which component of Fick's Law can be manipulated in the clincial setting?
Maximal volume of air that can be inhaled after normal expiration (=tidal volume +IRV)
2 main forces that must be overcome during breathing?
Where is the majority of the surface area of the lung located?
low partial pressure of oxygen in blood
given change in lung volume per given changes in pleural pressure
Has Z numbers spanning from Z17-Z23
Volume of air that can be exhaled as forcibly and rapidly as possible from total lung capacity
Gas moves across the alveoli via _____ diffusion
T/F: The terminal bronchioles are surrounded by smooth muscle
T/F: Gas exchange ocurrs in the conducting airways.
Volume of air that can be exhaled after normal expiration (=total lung capacity - residual volume)
Is the airflow in the conducting airways laminar or turbulent?
T/F: During inspiration, the transpleural pressure difference becomes greater and allows for expansion of the lungs and alveoli.
Principal(or Law) that provides the basis for airflow in the lung
True or False: The rate of diffusion is proportional to the area of the membrane and inversely proportional to it thickness
inversely proportional to lung compliance
Z number or generation number for the trachea
As the diaphragm contracts. the volume increases in the pleural space. What happens to the pleural pressure?
T/F: An increase in particle size increases rate of diffusion

Volume of air in lungs remaining after maximal expiration
Lung recoils is used during ____.
Volume of air in the respiratory or alveolar airways (mL)
T/F: During inspiration, the pressure in the alveolus become sub-atmospheric, allowing air from the atmosphere to move into the lungs.
