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