laws Flashcards
At a constant temperature, the pressure exerted by a gas varies inversely with the volume of the gas
boyles law
P=2T/r describes the relationship between alveolar radius and the tendency to collapse. A smaller alveolar radius means a higher tendency to collapse
law of la place
Fick’s law of diffusion
Gas diffusion across a surface is inversely proportional to surface thickness and proportional to area
The total pressure of a mixture of gases equals the sum of the partial pressures of each component gas
daltons law
henrys law
The amount of a gas dissolved in a given type and volume of liquid at constant temperature is proportional to the partial pressure of the gas in equilibrium with the liquid
haldane effect
As O2 is removed from Hb, Hb’s ability to pick up CO2 and CO2-generated H+ ions is increased
bohr effect
The oxygen dissocation curve is shifted right due to conditions in the tissues, meaning more oxygen is released
