Documentation

The isTractSegmentof property.

This ternary property defines a segment in a substance tract and position it as initial or successor of another segment in the same tract.

In essence a substance tract is made of segments appended in a row, each one transporting the substance of the tract to the next segment. Alltogether they achieved the transport of te substance from the entry to the exit of the substance tract. The segments are either organs or cardinal body parts. Any segment can itself be constituted of subsegments.

Formally, a segment is defined at minima as constituent part of a substance tract, and is always positioned as distal to its preceeding segment. Additional defining information is not necessary, but may be present.
