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