Q
Give 3 features of an anatomical compartment
A
- Has defined boundaries that change in the direction of the membrane
- Contents inside
- independent self-sufficient units
4
Q
What are the two classes of anatomical spaces
A
- True anatomical spaces - these are spaces that occur normally
- Potential spaces - these are spaces that don’t exist normally and can be as a result of pathologies that create new spaces
