Study Notes
Henry's Law
- At equilibrium, the amount of gas dissolved in a given volume of fluid at a given temperature is directly proportional to the partial pressure of the gas.
- This law applies to the transfer of gases from the alveoli into the plasma in pulmonary capillaries and then into red blood cells (RBCs).
General Gas Law
- Gases move from an area of higher pressure to an area of lower pressure.
Graham's Law of Diffusion
- The rate of diffusion of two gases is inversely proportional to the square root of their molecular weights.
- This law explains how gases diffuse through a medium, such as air or water.
Dalton's Law of Partial Pressure
- The pressure exerted by a gas in a mixture of gases is the same as the pressure it would exert if it were the only gas present.
- This law applies to the behavior of gases in a mixture, such as the air we breathe.
Boyle's Law
- Changes in intrapulmonary pressure occur as a result of changes in lung volume.
- The pressure of a gas is inversely proportional to its volume.
- When lung volume increases, intrapulmonary pressure decreases, allowing air to enter the lungs.
- When lung volume decreases, intrapulmonary pressure increases above atmospheric pressure, causing air to leave the lungs.
