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