QuestionAnswer
Has a Z number that spans from Z0-Z16
True or False: The rate of diffusion is proportional to the area of the membrane and inversely proportional to it thickness
Volume of air in the conducting airways (mL)
T/F: The terminal bronchioles are surrounded by smooth muscle
T/F:An Increase in molecule solubility increases rate of diffusion
The diaphragm, the external intercostals, and the sternocleidomastoids are important for _____.
Is the airflow in the conducting airways laminar or turbulent?
Lung recoils is used during ____.
T/F: During inspiration, the transpleural pressure difference becomes greater and allows for expansion of the lungs and alveoli.
The internal intercostals and the abdominal muscle are important for ____.
Volume of exhaled air with every breath is known as ____ volume.
Which component of Fick's Law can be manipulated in the clincial setting?
pressure in the atmosphere is ___ cm h20
patients with pulmonary fibrosis have a ___ lung recoil
Z number or generation number for the trachea
Maximal volume of air that can be inhaled after normal expiration (=tidal volume +IRV)
If the transpulmonary pressure is +3, then the lungs are ____ (collapsing or expanding).
low partial pressure of oxygen in blood
most important muscle for inspiration
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
Volume of air in lungs after maximal expiration
T/F: An increase in particle size increases rate of diffusion
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)?
These bronchi are the site of highest resistance to airflow and are surrounded by smooth muscle
Normal Tidal Volume in liters
Function of these airways is to clean, condition, and warm air
pressure in the pleural cavity is normally ____ cm H2O at the end of a tidal volume breath
QuestionAnswer
Where is the majority of the surface area of the lung located?
Which gas is the first to be affected by a diffusion limited disorder?
site of gas exchange in the lung
Volume of air remaining in the lungs after a normal expiration
Volume of air in the respiratory or alveolar airways (mL)
Is the airflow in the respiratory or alveolar airways laminar or turbulent?
Gas moves across the alveoli via _____ diffusion
pressure difference between the alveoli and the pleural space is known as ____ ____.
T/F: Gas exchange ocurrs in the conducting airways.
given change in lung volume per given changes in pleural pressure
Work during breath occurs on ____.
Essential muscle in creating differences in transpleural pressure
Total volume of air in lungs after maximal inspiration
2 main forces that must be overcome during breathing?
T/F: During inspiration, the pressure in the alveolus become sub-atmospheric, allowing air from the atmosphere to move into the lungs.
T/F: A 'diffusion limited' A-a gradient is smaller than under normal circumstances.
inversely proportional to lung compliance
Has Z numbers spanning from Z17-Z23
units for measurement of transpulmonary pressure
As the diaphragm contracts. the volume increases in the pleural space. What happens to the pleural pressure?
Principal(or Law) that provides the basis for airflow in the lung
Volume of air that can be exhaled as forcibly and rapidly as possible from total lung capacity
patients with emphysema have a ____ lung compliance
Average Lung Compliance for a tidal volume in L/cm H20 (Avg Volume = .5 and change in Pressure= 2.5)
low partial pressure of oxygen in tissues
Volume of air that can be exhaled after normal expiration (=total lung capacity - residual volume)
Volume of air than can be inhaled at the end of a normal breath
Volume of air in lungs remaining after maximal expiration
