What is the word for bifurcation but with multi-branching?

  1. Jan 30, 2016 #1
    I thought it would be polyfurcation but it s not in dictionary. Also if blood vessels use venturi effect to lower pressure in some places, what is the extra speed used for?

    Furcation is the term for Multi-branching, Bi-furcation implies it splits into 'only' 2 branches, at that junction.

    The venturi effect occurs on the outflow, which implies the pressure is decreased because the volume is evacuated more quickly.

    Fwiw, I am not a Medical practitioner but I did have a ASD, WPW, and DoKB repair a large number of years ago. :-)
