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