What are the three types of capillaries?
Where are they found?

Continuous capillaries:
- Continuous thin layer of ...cells surrounded by membrane
- .... for quick and easy exchange of gas and solutes
- ...within endothelial cells that limit passage of substances
- ... that can cause constriction or relaxation

Fenestrated capillary:
- Endothelium perforated by ... (Except glomerulus)
- ....within endothelium that allows .... to go through more easily

Discontinious capillary:
- ....gaps
- Located in places where ...
- Basement membrane has .... to allow cells to go through
- that show the gaps
