Chapter 22 Outline
Outline
The Properties of Gases in Gas Mixtures and Aqueous Solutions
- Gases in the gas phase
- Gases in aqueous solution
Diffusion of Gases
- Gases diffuse far more readily through gas phases than through aqueous solutions
- Gas molecules that combine chemically with other molecules cease to contribute to the gas partial pressure
- BOX 22.1 Diffusion through Tissues Can Meet O2 Requirements over Distances of Only 1 Millimeter or Less
Convective Transport of Gases: Bulk Flow
- BOX 22.2 Induction of Internal Flow by Ambient Currents
- Gas transport in animals often occurs by alternating convection and diffusion
