Part of speech: noun

Pronunciation: /pəɹˈfjuʒən/

Definitions

3. The process of supplying blood or another fluid to tissues to maintain cellular health and function

Etymology: The word's shape is a clear picture of its meaning: it comes from Latin "perfundere", "to pour over" or "pour through", built from "per" (through, thoroughly) and "fundere" (to pour). The Latin noun "perfūsiō" was the act of pouring over something, and that literal sense of liquid flowing over a surface is still present in the modern medical meaning, where fluid is pushed through blood vessels or tissue. The route into English ran through Middle French, which had "perfusion" before English adopted it. English borrowed the term directly from that French form, so the Latin ancestor and the modern medical sense are linked by a single unbroken pouring motion.
