It has been said the most efficient way to conduct fluids over and into a surface or body is through branching. You can see that in river veins, blood veins, tree branches, coral, etc. Going a specific distance, then branching, each branch going a certain distance, then each one of those branching. It is a concept of growth, physical and mental. In the brain we can make new branches, pathways to learning. The more often they are traveled, the easier it becomes. The cessation of growth is the inability, literally, to branch out.
Below are a few photos to illustrate branching systems. Again more examples of beautiful solutions.
