QuestionAnswer
Has Z numbers spanning from Z17-Z23
Is the airflow in the respiratory or alveolar airways laminar or turbulent?
Which component of Fick's Law can be manipulated in the clincial setting?
Lung recoils is used during ____.
Work during breath occurs on ____.
T/F: During inspiration, the pressure in the alveolus become sub-atmospheric, allowing air from the atmosphere to move into the lungs.
pressure in the pleural cavity is normally ____ cm H2O at the end of a tidal volume breath
A ____ in surface area and a _____in membrane thickness can cause the lung to become diffusion limited.
The internal intercostals and the abdominal muscle are important for ____.
True or False: The rate of diffusion is proportional to the area of the membrane and inversely proportional to it thickness
most important muscle for inspiration
Volume of air in lungs remaining after maximal expiration
As the diaphragm contracts. the volume increases in the pleural space. What happens to the pleural pressure?
Normal Tidal Volume in liters
T/F: Gas exchange ocurrs in the conducting airways.
Maximal volume of air that can be inhaled after normal expiration (=tidal volume +IRV)
low partial pressure of oxygen in blood
Is the airflow in the conducting airways laminar or turbulent?
Z number or generation number for the trachea
2 main forces that must be overcome during breathing?
On average, how much time does an RBC spend in the respiratory airways (sec)?
These bronchi are the site of highest resistance to airflow and are surrounded by smooth muscle
Principal(or Law) that provides the basis for airflow in the lung
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.
Volume of air that can be exhaled after normal expiration (=total lung capacity - residual volume)
pressure in the atmosphere is ___ cm h20
If the transpulmonary pressure is +3, then the lungs are ____ (collapsing or expanding).
Volume of air in the respiratory or alveolar airways (mL)
QuestionAnswer
Function of these airways is to clean, condition, and warm air
Essential muscle in creating differences in transpleural pressure
T/F: The terminal bronchioles are surrounded by smooth muscle
pressure difference between the alveoli and the pleural space is known as ____ ____.
patients with pulmonary fibrosis have a ___ lung recoil
T/F:An Increase in molecule solubility increases rate of diffusion
Which gas is the first to be affected by a diffusion limited disorder?
The diaphragm, the external intercostals, and the sternocleidomastoids are important for _____.
Volume of air in lungs after maximal inspiration
T/F: A 'diffusion limited' A-a gradient is smaller than under normal circumstances.
Where is the majority of the surface area of the lung located?
inversely proportional to lung compliance
Maximal Volume that can be exhaled at the end of a tidal volume
Gas moves across the alveoli via _____ diffusion
low partial pressure of oxygen in tissues
Volume of air that can be exhaled as forcibly and rapidly as possible from total lung capacity
Volume of air than can be inhaled at the end of a normal breath
Volume of exhaled air with every breath is known as ____ volume.
Average Lung Compliance for a tidal volume in L/cm H20 (Avg Volume = .5 and change in Pressure= 2.5)
Volume of air in lungs after maximal expiration
Volume of air remaining in the lungs after a normal expiration
T/F: An increase in particle size increases rate of diffusion
given change in lung volume per given changes in pleural pressure
units for measurement of transpulmonary pressure
site of gas exchange in the lung

Has a Z number that spans from Z0-Z16
