A.Word.A.Day

PRONUNCIATION:

(puhr-FYOO-zhuhn)

MEANING:

noun:
1. The spreading of a liquid, color, light, aroma, etc.
2. The passage of a fluid through an organ or tissue, for example, to supply nutrients or oxygen.

ETYMOLOGY:

From Latin perfundere (to drench), from per- (through) + fundere (to pour). Earliest documented use: 1574.

USAGE:

“Meanwhile, eGenesis has approval for a trial of a pig-liver perfusion . Unlike a full transplant, this keeps the organ outside the patient’s body, although hooked up to his circulatory system. With help from an organ-preserving device developed by OrganOx, a spin-out from the University of Oxford, the hope is that the pig liver can keep the patient alive until a human organ is ready.”
A New Lease of Life; The Economist (London, UK); Nov 1, 2025.
