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