Gas Exchange Partial Pressure Flashcards
Concentration of a gas in either a gaseous or liquid environment is referred
Partial pressure
Atmospheric pressure may be measured in what and so a composite of the what
MmHg and composite of partial pressures of all the gases within it
One atmosphere is equal to
760mmHg
Partial pressures of oxygen and carbon dioxide can therefore be calculated from what
Their relative proportions in air
What other property of oxygen and carbon dioxide in water regulates the diffusion
Relative solubility
Water solubility is important why?
Gases have to diffuse through watery environment
What has watery environments
Fluid that coats alveoli, cytoplasm if type 1 cells, cytoplasm of capillary endothelial cells, blood plasma, cytoplasm of red blood cells
Is carbon dioxide or oxygen more soluble in water
Carbon dioxide
What promotes gas movements
Differences in partial pressures and relative solubilities
Movement of oxygen and carbon dioxide is due to what
Diffusion
