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