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