Work during breath occurs on ____.
T/F: Gas exchange ocurrs in the conducting airways.
T/F: During inspiration, the pressure in the alveolus become sub-atmospheric, allowing air from the atmosphere to move into the lungs.
On average, how much time does an RBC spend in the respiratory airways (sec)?
Normal Tidal Volume in liters
Volume of air in the respiratory or alveolar airways (mL)
Function of these airways is to clean, condition, and warm air
Total volume of air in lungs after maximal inspiration
Volume of air remaining in the lungs after a normal expiration
Volume of air in lungs after maximal expiration
If the transpulmonary pressure is +3, then the lungs are ____ (collapsing or expanding).
T/F: An increase in particle size increases rate of diffusion
site of gas exchange in the lung
T/F: The terminal bronchioles are surrounded by smooth muscle
The internal intercostals and the abdominal muscle are important for ____.
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 inspiration
Maximal volume of air that can be inhaled after normal expiration (=tidal volume +IRV)
Where is the majority of the surface area of the lung located?
As the diaphragm contracts. the volume increases in the pleural space. What happens to the pleural pressure?
Lung recoils is used during ____.
Average Lung Compliance for a tidal volume in L/cm H20 (Avg Volume = .5 and change in Pressure= 2.5)
low partial pressure of oxygen in tissues
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?
pressure in the atmosphere is ___ cm h20
Z number or generation number for the trachea
Volume of air in lungs remaining after maximal expiration
A ____ in surface area and a _____in membrane thickness can cause the lung to become diffusion limited.
Gas moves across the alveoli via _____ diffusion
Is the airflow in the conducting airways laminar or turbulent?
patients with emphysema have a ____ lung compliance
Essential muscle in creating differences in transpleural pressure
Principal(or Law) that provides the basis for airflow in the lung
pressure in the pleural cavity is normally ____ cm H2O at the end of a tidal volume breath
These bronchi are the site of highest resistance to airflow and are surrounded by smooth muscle

patients with pulmonary fibrosis have a ___ lung recoil
given change in lung volume per given changes in pleural pressure
Volume of air that can be exhaled after normal expiration (=total lung capacity - residual volume)
most important muscle for inspiration
Volume of exhaled air with every breath is known as ____ volume.
Is the airflow in the respiratory or alveolar airways laminar or turbulent?
inversely proportional to lung compliance
Which component of Fick's Law can be manipulated in the clincial setting?
Has Z numbers spanning from Z17-Z23
Has a Z number that spans from Z0-Z16
Maximal Volume that can be exhaled at the end of a tidal volume

pressure difference between the alveoli and the pleural space is known as ____ ____.
