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