The Venous Graph. A theoretical review of basic scientific topics about venous circulation.

Our every-day knowledge of the venous circulation uses very practical and effective points of view.

This approach however creates a block of communication to people working in other scientific fields, because our knowledge does not share with these fields a common scientific language.

This research tries to fill this gap, reviewing some basic scientific topics about venous circulation:

• Graph theory applied to venous net
• Resolution methods for electrical circuits applied to venous ones.
• Non linear elements in circuits as diodes or venous valves.
• DC and AC circuits compared to venous regimens with mean and actual velocity.
• Graph as a database, while paths can be considered as queries on the database and not real structures.
• Direction of flow, physiological and pathological directions as an useful point of view, which helps us to make qualitative evaluations, but is not necessary to an analytical description or resolution of the graph.
