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