Body fluids and compartments
More than half of you is water, but it is not one pool. It sits in compartments with very different chemistry, and water and solutes move between them all the time. This topic maps those compartments and the forces that move fluid between them.
In this topic
- A body made mostly of water
- Two main compartments
- Worked example: compartment volumes
- Different chemistry inside and out
- Water follows solutes
- Pressure moves fluid out of capillaries
- Worked example: water versus isotonic saline
- How losses spread
- Edema
- Common mistakes to avoid
- Key takeaways
