answers
Dalton's Law - ✔✔Law of partial pressures || || || || || ||
The proportion of the total pressure exerted by a gas mixture that an individual gas exerts is
|| || || || || || || || || || || || || || || || || ||
called PARTIAL PRESSURE || ||
Calculating Partial Pressure - ✔✔multiply the percent of that gas by the absolute pressure
|| || || || || || || || || || || || ||
ex. P02 at 99 ft = .21 x 4 bar = .84 bar
|| || || || || || || || || || || ||
Henry's Law - ✔✔gas exchange law || || || || ||
"the amount of gas that dissolves into a liquid at a given temperature is directly proportional to the
|| || || || || || || || || || || || || || || || ||
partial pressure of that gas"
|| || || || ||
What factors effect speed of gas dissolution in a liquid? - ✔✔1) pressure of the gas
|| || || || || || || || || || || || || || ||
2) amount already dissolved in the liquid
|| || || || || ||
3) solubility of the gas in the liquid
|| || || || || || || ||
4) SA where the gas and liquid make contact
|| || || || || || || ||
hemoglobin - ✔✔protein that binds reversibly with oxygen in the lungs (found in RBCs)
|| || || || || || || || || || || || ||
gives up oxygen for the tissues to use
|| || || || || || ||
where does gas exchange take place? - ✔✔capillaries - microscopic vessels between arteries and
|| || || || || || || || || || || || || ||
veins that thread through the tissues
