1
Q
Diffusion of gases through the respiratory membrane depends upon four factors…
A
- Membrane thickness
- Diffusion coefficient of gas
- Surface area
- Partial pressure differences
2
Q
Daltons law
A
Each gas in a mixture of gases exerts its own pressure (as if all other gases were not present)
Total pressure is sum of all partial pressures
3
Q
Henry’s law
A
Concentration of a gas in a liquid is determined by
its partial pressure and its solubility coefficient
