Etymology: The Latin noun "vas" meant "vessel" or "container," a plain word for a jar, dish or bowl. English borrowed it in the mid-17th century, around 1645 to 1655, when anatomists needed a term for the tubes that carry blood and other fluids through the body. The choice was a deliberate piece of scientific borrowing: rather than inventing something new, writers reached back to a Latin word that already described a hollow thing holding liquid. The word's Latin sense of an ordinary container is what makes the anatomical use so intuitive. A blood vessel is, after all, a hollow passage that holds and channels what moves through it, and the original image of a vessel as a receptacle carried straight over into the body. The word's plural, "vasa," keeps its Latin form in English technical writing, a reminder of where the term came from.
