Homodynamic?

In sending a work related e-mail, Outlook suggested a swap of homodynamic for hemodynamic... which I had no idea was even a word and conjures up all sorts of amusing images to my immature mind(a mill powered by FABULOUS?)... but it also had this definition.

Ho`mo`dy`nam´ic
a.1. Homodynamous.

Indeed.

Which, if you follow the winding road down to the bottom leads to:

Any of the homologous segments, lying in a longitudinal series, that compose the body of certain animals, such as earthworms and lobsters. Also called somite.

WTF. People who study earthworms get their jargon in Outlook, but I use the proper term for the regulation of blood pressure and I might as well be speaking French? Jeez. Is there some sort of all powerful metameres lobby I don't know about?
